The posterior nasal nerve plays an important role on cardiopulmonary reflexes to nasal application of capsaicin, distilled water and l-menthol in anesthetized dogs. (1/983)

The sensory innervation of the cardiopulmonary reflexes to nasal application of capsaicin (CAPS), distilled water (DW) and l-menthol (LM) was studied in anesthetized dogs breathing through tracheostomy. A marked cardiopulmonary reflex was observed by CAPS and DW into the nasal cavity, while a prolongation of expiration was induced by LM. All these reflexes were significantly decreased by bilateral section of the posterior nasal nerve (PNN) and completely abolished by topical nasal anesthesia with lidocaine. Responses of the whole nerve activity of the PNN to these substances corresponded to the magnitude of the reflexes. These results indicate that PNN afferents play an important role on the reflex elicitation of the noxious, water and cold stimuli from the nasal cavity.  (+info)

Nasal nitric oxide concentration in paranasal sinus inflammatory diseases. (2/983)

In normal upper airways, nitric oxide is generated by the paranasal sinus epithelium and then diffuses into the nasal cavities. This study examined whether or not nasal NO concentration is affected by paranasal sinus inflammatory diseases. The influence of obstruction (nasal polyposis) and/or inflammation (allergy or chronic sinusitis) of the paranasal sinuses on nasal NO concentration was evaluated in nasal allergic (n=7 patients) or nonallergic (n=20) polyposis, nonallergic chronic sinusitis (n=10) and Kartagener's syndrome (n=6) and compared with control subjects (n=42). A score of alteration of the paranasal sinus (number of altered and occluded sinuses) was determined by a computed tomography scan. The nasal NO concentration in nasal nonallergic polyposis (150+/-20 parts per billion (ppb)) was significantly decreased compared with both controls (223+/-6 ppb, p=0.01) and polyposis with allergy (272+/-28 ppb, p<0.0001). In each group, the nasal NO concentration was inversely correlated with the extent of tomodensitometric alteration of the paranasal sinuses. In Kartagener's syndrome, the nasal NO concentration (14+/-2 ppb) was drastically decreased compared with all other groups, despite the presence of open paranasal sinuses. Thus, the nasal NO concentration in patients with nasal polyposis appeared to be dependent on both the allergic status and the degree of obstruction of the paranasal sinuses.  (+info)

Salivary contribution to exhaled nitric oxide. (3/983)

Dietary and metabolic nitrate is distributed from the blood to the saliva by active uptake in the salivary glands, and is reduced to nitrite in the oral cavity by the action of certain bacteria. Since it has been reported that nitric oxide may be formed nonenzymatically from nitrite this study aimed to determine whether salivary nitrite could influence measurements of exhaled NO. Ten healthy subjects fasted overnight and ingested 400 mg potassium nitrate, equivalent to approximately 200 g spinach. Exhaled NO and nasal NO were regularly measured with a chemiluminescence technique up to 3 h after the ingestion. Measurements of exhaled NO were performed with a single-breath procedure, standardized to a 20-s exhalation, at a flow of 0.15 L x s(-1), and oral pressure of 8-10 cmH2O. Values of NO were registered as NO release rate (pmol x s(-1)) during the plateau of exhalation. Exhaled NO increased steadily over time after nitrate load and a maximum was seen at 120 min (77.0+/-15.2 versus 31.2+/-3.0 pmol x s(-1), p<0.01), whereas no increase was detected in nasal NO levels. Salivary nitrite concentrations increased in parallel; at 120 min there was a four-fold increase compared with baseline (1.56+/-0.44 versus 0.37+/-0.09 mM, p<0.05). The nitrite-reducing conditions in the oral cavity were also manipulated by the use of different mouthwash procedures. The antibacterial agent chlorhexidine acetate (0.2%) decreased NO release by almost 50% (p<0.01) 90 min after nitrate loading and reduced the preload control levels by close to 30% (p<0.05). Sodium bicarbonate (10%) also reduced exhaled NO levels, but to a somewhat lesser extent than chlorhexidine acetate. In conclusion, salivary nitric oxide formation contributes to nitric oxide in exhaled air and a large intake of nitrate-rich foods before the investigation might be misinterpreted as an elevated inflammatory activity in the airways. This potential source of error and the means for avoiding it should be considered in the development of a future standardized method for measurements of exhaled nitric oxide.  (+info)

Protection against influenza virus infection of mice fed Bifidobacterium breve YIT4064. (4/983)

Mice fed Bifidobacterium breve YIT4064 and immunized orally with influenza virus were more strongly protected against influenza virus infection of the lower respiratory tract than ones immunized with influenza virus only. The number of mice with enhanced anti-influenza virus immunoglobulin G (IgG) in serum upon oral administration of B. breve YIT4064 and oral immunization with influenza virus was significantly greater than that upon oral immunization with influenza virus only. These findings demonstrated that the oral administration of B. breve YIT4064 increased anti-influenza virus IgG antibodies in serum and protected against influenza virus infection. The oral administration of B. breve YIT4064 may enhance antigen-specific IgG against various pathogenic antigens taken orally and induce protection against various virus infections.  (+info)

Capsaicin-sensitive C-fiber-mediated protective responses in ozone inhalation in rats. (5/983)

To assess the role of lung sensory C fibers during and after inhalation of 1 part/million ozone for 8 h, we compared breathing pattern responses and epithelial injury-inflammation-repair in rats depleted of C fibers by systemic administration of capsaicin as neonates and in vehicle-treated control animals. Capsaicin-treated rats did not develop ozone-induced rapid, shallow breathing. Capsaicin-treated rats showed more severe necrosis in the nasal cavity and greater inflammation throughout the respiratory tract than did control rats exposed to ozone. Incorporation of 5-bromo-2'-deoxyuridine (a marker of DNA synthesis associated with proliferation) into terminal bronchiolar epithelial cells was not significantly affected by capsaicin treatment in rats exposed to ozone. However, when normalized to the degree of epithelial necrosis present in each rat studied, there was less 5-bromo-2'-deoxyuridine labeling in the terminal bronchioles of capsaicin-treated rats. These observations suggest that the ozone-induced release of neuropeptides does not measurably contribute to airway inflammation but may play a role in modulating basal and reparative airway epithelial cell proliferation.  (+info)

LMR spectroscopy: a new sensitive method for on-line recording of nitric oxide in breath. (6/983)

Laser magnetic resonance spectroscopy (LMRS) is a sensitive and isotope-selective technique for determining low concentrations of gaseous free radicals with high time resolution. We used this technique to analyze the nitric oxide (NO) concentration profile while simultaneously measuring the flow and expired volume during several single breathing cycles. Eight healthy, nonallergic volunteers were investigated. An initial NO peak was found in all breathing cycles before the NO concentration dropped to a relatively stable plateau in the late phase of expiration. The nasal NO peak was significantly higher than the oral NO peak. The nasal NO plateau was always higher than the oral NO plateau. The height of the initial nasal and oral NO peak rose with increasing duration of breath hold, whereas the late expiratory NO plateau changed only little for either the nasal or the oral breathing cycles. Our findings demonstrate, in line with other reports using other techniques, that the nose is the primary source for NO within the airways.  (+info)

Anatomical structure and surface epithelial distribution in the nasal cavity of the common cotton-eared marmoset (Callithrix jacchus). (7/983)

To validate use of the common cotton-eared marmoset (Callithrix jacchus) in inhalation toxicity studies, its nasal morphology was examined. The nasal turbinates each consisted of one maxilloturbinate and one ethmoturbinate: these were more planar in structure than the comparable structures of rodents or dogs. The nasal cavity epithelia comprised squamous epithelium (SE), nasal transitional epithelium (NTE), respiratory epithelium (RE) and olfactory epithelium (OE), listed in order of occurrence from anterior to posterior positions. NTE was distributed as a narrow band lying between SE and RE. OE was limited to the dorsal part of the cavity, which was structurally similar to that of the macaque or man. Overall, this study revealed structural the similarity of the whole nasal cavity in the marmoset to that of macaques or humans. Prediction of nasal cavity changes in man based on extrapolation from experimentally induced changes in the common marmoset therefore seems likely to be feasible, making it a useful animal model for inhalation studies.  (+info)

Evidence for nasal carriage of methicillin-resistant staphylococci colonizing intravascular devices. (8/983)

Nasal surveillance cultures were performed for 54 patients exhibiting >/=10(3) CFU of methicillin-resistant coagulase-negative staphylococci per ml in central venous catheter (CVC) rinse cultures over a 6-month period. Forty-two of the nasal cultures yielded growth of methicillin-resistant coagulase-negative staphylococci, and 33 of the 42 cultures contained organisms that belonged to the same species as the CVC isolates. Of the 33 same-species isolates, 20 appeared to be identical strains by pulsed-field gel electrophoresis analysis. These data suggest that measures should be taken to reduce cross-contamination between the respiratory tract and intravascular devices. However, the potential interest in detecting methicillin-resistant coagulase-negative staphylococcus carriage in high-risk patients is hampered by the lack of sensitivity of nasal surveillance cultures.  (+info)

The nose cavity is divided into a right and left passageway. The tissue that covers the wall of your nasal cavity contains many blood vessels. Heat from the blood in the vessels helps warm the air as you breathe. Moisture (small amount of water) is added to the air you breath by special cells in the walls of the nasal cavity. The air is warmed and moistened before it reaches your lungs. Cilia (small hairs) and mucus along the inside wall of the nasal cavity trap and remove dust and germs from the air as it flows through the nasal cavity. The cilia move the mucus down the nasal cavity to the pharynx, where it can be swallowed. ...

CASE DESCRIPTION: A 12-year-old 500-kg (1,100-lb) American Quarter Horse mare was evaluated because of chronic mucopurulent, bloody discharge from the left nostril, inspiratory dyspnea, and respiratory noise. CLINICAL FINDINGS: The horse had severe inspiratory dyspnea and stertorous respiration with no airflow from the left nostril. A temporary tracheostomy was performed. Endoscopy revealed a tan mass protruding from the left middle nasal meatus into the left common nasal meatus; it extended caudally into the nasopharynx and around the caudal edge of the nasal septum into the right nasal cavity. Radiographically, a soft tissue opacity was evident in most of the left nasal cavity and left paranasal sinuses. Cytologic examination of mass tissue revealed evidence of pyogranulomatous rhinitis; thickly encapsulated, budding yeast typical of Cryptococcus neoformans were detected. TREATMENT AND OUTCOME: While the horse was sedated and in a standing position, the fungal granuloma was removed from the paranasal
A gas administering method for administering gas to an airway of a patient having a nasal vestibule and for use with a gas administering apparatus comprises a primary gas source that is operable to provide gas and a nasal vestibular portion arranged so as to receive the gas from the primary gas source. Further, the nasal vestibular portion is capable of releasing the primary gas into the nasal vestibule. The method comprises inserting the nasal vestibular portion into the nasal vestibule, forming a seal between the nasal vestibular portion and an inner surface of the nasal vestibule, administering an amount of a gas from the primary gas source at a constant flow rate into the nasal vestibule via the nasal vestibular portion, and administering an anesthetic to the patient. The anesthetic induces depression of a portion of the nervous system of the patient. Furthermore, the seal promotes airway pressure buildup that is sufficient to prevent obstruction of the airway during depression of at least a portion

The respiratory system can be conceptually divided into upper and lower regions at the point of the epiglottis, the structure that seals off the lower respiratory system from the pharynx during swallowing (Figure 17.2). The upper respiratory system is in direct contact with the external environment. The nares (or nostrils) are the external openings of the nose that lead back into the nasal cavity, a large air-filled space behind the nares. These anatomical sites constitute the primary opening and first section of the respiratory tract, respectively. The nasal cavity is lined with hairs that trap large particles, like dust and pollen, and prevent their access to deeper tissues. The nasal cavity is also lined with a mucous membrane and Bowmans glands that produce mucus to help trap particles and microorganisms for removal. The nasal cavity is connected to several other air-filled spaces. The sinuses, a set of four, paired small cavities in the skull, communicate with the nasal cavity through a ...

The inflammatory diseases include rhinitis, sinusitis, and rhinosinusitis. A photodynamical therapy is also described, applying photosensitizing substances before the treatment with light. The phototherapeutical method is also effective for the prevention of
The Rapid Antigen Test is easy to use and takes place as a smear in the anterior nasal cavity to determine the detection of antigens.
A dilator/insert internally support the lateral nasal walls and securely stay in place without discomfort. It stays inserted by a pair of ledges (9 a and 10 a) and/or catches (7 a and 8 a), each resting behind a respective: limen nasi ridge (a somewhat vertical central protuberance on a lateral nasal wall); and/or a foot of the columella (the meaty protuberance peripherally off the base of the columella). The insert is confined from shifting off those protuberances by being tall (distance between 1 a and 2 a); almost as tall near the entrances of the nose as the entrances themselves. When worn, the bridge (1 a and 2 a)/leg (3 a , 4 a an 5 a , 6 a) assemblies look like two central nose rings. The peripheral rigidity of the bridge/leg assemblies braces the lateral walls of the nose apart and keeps the ledges in position. Catches can position midway rearward on bottom legs; and they extend centrally enough to rest behind, without engaging, the feet of the columella. The function of the described
The velie das Gaumensegel consists of the velum and the uvula together. In other words, it is the moveable rear portion of the roof of the mouth, which can be raised in order to close off the nasal passage as we do when swimming underwater without holding our nose.. In speaking, the velie is kept raised to close off the nasal cavity, except when producing nasal or nasalized sounds see 8, below. The nasal cavity die Nasenhohle is the passage through which air can pass by way of the nose to and from the throat. It can be and normally is sealed off during speech, except to produce a nasal nasal, der Nasenlaut or nasalized nasaliert sound. In producing a nasal sound, the air from the lungs does not exit by way of the oral cavity, but exclusively through the 10 Phonetics nasal cavity, whereas a nasalized sound is an oral sound produced with the velie not sealed and consequently with some air passing simultaneously through the nasal cavity.. The oral cavity die Mundhohle is simply the mouth. Sounds ...
The nasal cavity (or cavity of nose, latin: cavum nasi, cavitas nasi) is an irregular, bilateral air-filled space located above the roof of the mouth forming the internal part of the nose.
Doctors give trusted answers on uses, effects, side-effects, and cautions: Dr. Gilroy on widening nasal cavities: a deviated septum can be corrected surgically to bring the septum to the midline. If there are symptoms like nasal obstruction, snoring or recurrent sinusitis, have your nose evaluated by a board certified otolaryngologist.
0100] [0101] 1a) A 30-year-old male has seasonal allergic rhinitis. In May, prior to pollen formation, 30 units of BoNT topically applied in each nostril. Specifically, the nasal cavity is sprayed with a solution of 1% lidocaine and 1/2% neosynephrine to anesthetize and decongest the nasal mucosa, respectively. Then 1 cc of normal saline containing 30 units of BoNT is sprayed into each nasal cavity. This method of delivery, although commonly used for application of nasal medication, is inherently inefficient as a significant percentage of a sprayed medication will exit the posterior nasal cavity and be exhaled or swallowed. [0102] 1b) In another embodiment, the patient is treated by placing 1×3 cm2 cotton pledgets impregnated with 20 units of BoNT onto the medial surface of the turbinates and left for one hour, then removed by the physician. This delivery method is more efficient then a spray, however a significant percentage of the BoNT will not diffuse from the pledgets to the mucosa. [0103] ...

A fistula is characterized as an abnormal passageway between two openings, hollow organs, or cavities. They occur as a result of injury, infection, or disease. A communicating, vertical passageway between the mouth and nasal cavity is called an oronasal fistula.
This is an associated step to extended range. Resonation of tone occurs in the throat, nasal cavities and mouth. Every one of these involved cavities might help in producing different frequencies of sounds. If you would like your tone to become beautifully superb, you need to learn balancing these resonances. When you change from low to middle to high areas of your personal voice, these resonances may also change. When you sing low notes, theyll resonate in the mouth and throat. Moving higher, you can have the notes resonating behind your soft palate (soft area of tissue that divides the nasal cavity and mouth) toward the nasal cavities. It is possible to have the notes resonating in your mind from your nasal cavity whenever you sing in the highest selection of your voice.. Familiarize With Your Vocal Registers. Mentioned previously will be the modifications in resonance your voice undergoes whenever you shift through different levels of your tone. Such changes are occasionally known as vocal ...
Hey guys, just starting today my nasal cavity area is feeling really sensitive to cold air, but when i breathe hot air it feels great. It feels like theres a lot of mucus inside the area and its hard to get it.

Smell is one of the five most important senses (sight, hearing, touch and taste), allowing us to perceive life in its entirety. The perception of smell is a very complex process including the excitation of specialised receptors located in the human nasal cavity, and signal transmission to the brain. Smells are caused by volatile chemical compounds, which can often be recognised even when present in low concentrations. ...
Aqueous-based pharmaceutical composition - An aqueous pharmaceutical composition which is capable of being sprayed into the nasal cavity of an individual and which comprises: (A) a pharmaceutically effective amount of solid particles of medicament which is effective in treating a bodily condition by virtue of its being present on the mucosal surfaces of the nasal cavity; and (B) a suspending agent in an amount effective to maintain said particles dispersed uniformly in the composition and to impart to the composition the following thixotropic properties: (i) the viscosity of the position in unsheared form is relatively high, with the composition being in gel-like form; (ii) as the composition is subjected to shear (shaken) in preparation for spraying, the viscosity of the composition becomes relatively low and such that the composition in the form of a mist flows readily into the nasal passages for deposit on the mucosal surfaces of the nasal cavity; and (D) in deposited form on the mucosal ...

Internal surface of nasal cavity is covered with mucus. Due to the presence of mucus in the nasal cavity, the lining of it is moist. There are numerous cilia present on the lining of the nasal cavity. The bacteria, dust and other wastes found in inhaled air stick onto the mucus. This prevents the entry of them into the lungs. By rhythemic movement of cilia the waste materials are sent out. The materials that are collected at pharynx are removed out with saliva ...
Background The need for the timely collection of diagnostic biosamples during symptomatic episodes represents a major obstacle to large-scale studies on acute respiratory infection (ARI) epidemiology. This may be circumvented by having the participants collect their own nasal swabs. We compared self- and staff-collected swabs in terms of swabbing quality and detection of viral respiratory pathogens. Methodology/Principal Findings We conducted a prospective study among employees of our institution during the ARI season 2010/2011 (December-March). Weekly emails were sent to the participants (n = 84), reminding them to come to the study center in case of new symptoms. The participants self-collected an anterior nasal swab from one nostril, and trained study personnel collected one from the other nostril. The participants self-collected another two swabs (one from each nostril) on a subsequent day. Human β-actin DNA concentration was determined in the swabs as a quality control. Viral respiratory
The sinuses are hollow spaces located inside the bones in the skull to either side of the nose, behind and in between the eyes, in the forehead and at the back of the nasal cavity. The sinuses are lined with a moist, thin layer of tissue called a mucous membrane, which not only humidifies the air as you breathe it in, but also produces mucus to trap irritants such as dust, pollen and bacteria. The sinuses are lined with microscopic hairs called cilia. The function of cilia is to move mucus to flush the sinuses and nasal passageways of trapped irritants.. Sinus congestion is the blockage of one or more of the nasal passageways as a result of inflammation and swelling of the sinus tissues, secretion of mucus or a deviated septum (meaning obstruction of the nasal passage by the membranous ridge of cartilage in the nose that separates the nasal cavity into the two nostrils). Sinus congestion leads to impaired flow of mucus out of the sinuses. The build up of mucus in the sinuses causes increased ...
Less invasive nasal swab taken from front opening of the nose is more comfortable for patientsTest can be performed by doctors, school and company nurses, and medical assistants, in any location without specialized equipment IRVINE, Calif., May 11, 2021 (GLOBE NEWSWIRE) -- Biomerica, Inc. (Nasdaq: BMRA), a global provider of advanced medical products, announced that its new COVID-19 Antigen Rapid Test can now be performed with a simple less invasive nasal swab. This simple nasal swab, which takes the sample from the front opening of the nose, is less invasive and more comfortable for patients than the deep anterior nasal swab which is typically used. The test is highly portable, cost effective and provides visual results negating the need for any equipment to perform or read the test. The test also provides results in 15 minutes versus lab-run PCR tests which can take up to three days for results, thereby potentially expediting the process of identifying infectious people and preventing further spread
Although it may come as second nature to blow your nose to alleviate stuffiness, some argue that it reverses the flow of mucus into the sinuses and slows down the drainage.. Dr. J Owen Hendley, and other pediatric infectious disease researchers at the University of Virginia, conducted CT scans and other measurements as subjects coughed, sneezed and blew their noses, according to the New York Times. The subjects, in some cases, had an opaque dye dripped into their rear nasal cavities.. Coughing and sneezing generated little, if any, pressure in the nasal cavities. However, nose blowing generated enormous pressure, equivalent to a persons diastolic blood pressure reading, Hendley said. This pressure propelled mucus into the sinuses every time. Hendley also said that it was unclear whether this was harmful, but added that during sickness it could shoot viruses or bacteria into the sinuses, and possibly cause further infection.. Dr. Anil Kumar Lalwani, the chairman of the department of ...
In what can only be called a blessing, an unnamed 17-year-old boy has finally been gifted a new life by doctors who succeeded in removing a baseball-sized tumour from his nose. The unnamed 17-year-old is only the sixth ever recorded case of having an ultra-rare form of his nasal cavity in the world. He had been living with the tumour for more than a decade, which had hindered his breathing, eating and speaking abilities, compelling him to take medical help from surgeons in India. A three-hour surgery is what it took to remove the 750 gram growth, which was made up of blood vessels, from his nasal cavity. The surgeons had to bring down his blood pressure in order to prevent any life-threatening bleeding, as high pressure can cause vessels to rupture. According to a report in the Daily Mail, Dr J C Passey, from New Delhis Loknayank Jaiprakash Narayan Hospital, said: This tumour is rare and normally the size of a tennis ball. But in this case it looked like another head growing along the cheeks ...

Special Instructions for Large Volume Rinse: Stand in front of a sink, bend forward to comfort level and tilt your head down. Keep your mouth open and, without holding your breath, place the tip snugly in the nostril and squeeze the actuator until the solution starts draining from the opposite nasal passage or from your mouth. Allow the flow to continue for 2 to 3 seconds. Do not swallow the solution. Blow your nose gently, without pinching your nose completely, to avoid applying pressure on your eardrums. If tolerable, sniff in any residual solution remaining in the nasal passage once or twice prior to blowing your nose. This may clean out the posterior nasopharyngeal area, which is the area at the back of your nasal passage. At times, some solution may reach the back of your throat. If so, please spit it out. To help improve drainage of any residual solution, blow your nose gently while tilting your head to the side. Now repeat these steps on your other nasal passage. ...
Prior to insertion, the AlaxoLito Nasal Stent is pulled into a thin introduction tube (see Fig. 2). This is then introduced horizontally into the nose (in the middle or lower nasal passage). Subsequent retraction of the introduction tube from the nose leads to self-expansion of the nitinol braid. The ball-shaped widening is located at the nasal valve (see arrow in right photo in Fig. 3). The cylindrical portion of the stent splints the anterior (AlaxoLito 2) or the full (AlaxoLito 3) nasal passage. Stents are used in both the right and left nostril. The stents are easily self-inserted by patients and the design makes the stents hardly visible in the nostrils. (see Fig. 3). ...

The nasal cavity is divided into two lateral compartments separated down the middle by the nasal septum. The nasal cavity communicates anteriorly through the nostrils and posteriorly with the nasopharynx through openings called choanae. The nasal cavities and septum are lined with a mucous membrane and are richly vascularized by branches of the maxillary, facial, and ophthalmic arteries. The nasal cavity receives innervation via branches of the olfactory [cranial nerve (CN) I], ophthalmic (CN V-1), and maxillary nerves (CN V-2). ...
Objectives/Hypothesis Inspired air is heated and moistened as it passes the nasal cavity. The temperature increase should be similar to a heated tube model, depending on the airflow.. Study Design Intranasal temperature values of 50 volunteers were measured after inspiration at different locations: nasal vestibule, nasal valve area, anterior to the head of the middle turbinate, and the nasopharynx. Temperature values were related to nasal airway resistance data.. Methods Intranasal temperature measurements were made with a miniaturized thermocouple. Nasal airway resistance was detected by active anterior rhinomanometry.. Results A logarithmic increase of air temperature from the anterior segment of the nose to the posterior part was noted. In the nasopharynx temperature was approximately 34°C. The highest increase in temperature was observed in the nasal valve area.. Conclusions The temperature increase of ambient air in the nasal airways can be compared with a logarithmic curve of the heating ...
A nasal dilator that includes an upper resilient member for dilating the nasal valve and a lower resilient member for dilating the nostrils. The upper resilient member and lower resilient member may be attached to one another by a flexible substrate having a middle portion that is narrower in length than the upper or lower resilient members. The nasal dilator also may have adhesive tabs extending downwardly from the lower portion of the substrate on either side of the nose and towards the nostril entry, for temporary attachment to the side of the nasal vestibule to reduce nostril collapse. The nasal dilator also may include bendable or configurable hooks extending downwardly from the lower portion of the substrate and towards the nostril entrance for insertion into the nostril to reduce nostril collapse.
Background: Despite a growing number of studies using acoustic rhinometry (AR) in children, no reference material exists that incorporates the entire age and height interval of preschool children up to puberty for a range of rhinometric variables. The aim of this study is to provide a reference range for nasal volumes and minimum cross-sectional areas (MCAs) in healthy nondecongested children aged 4-13 years old. Methods: Two hundred fifty-six primary school children (mean, 7.95 years; range, 3.8-13.1 years; 123 boys/133 girls) were measured by AR. Variables were MCA (first, second, and absolute minimum) and nasal volumes from 0 to 4 cm (Vol0-4), 0 to 5 cm (Vol0-5), 1 to 4 cm (Vol1-4), and 2 to 5 cm (Vol2-5) into the nasal cavity. Height and weight were measured and atopic status was determined by skin-prick test. Age and current and past respiratory health were recorded from a questionnaire. Results: In multiple linear regression models height was the main predictor for all AR variables ...

Figure 1-39. Organs of the respiratory system.. Nasal Cavity. Air enters the nasal cavity through the nostrils (nares). Lining the nasal passages are hairs, which, together with the mucous membrane, entrap and filter out dust and other minute particles that could irritate the lungs. Incoming air is warmed and moistened in the chambers of the nasal cavity to prevent damage to the lungs. The nasal and oral cavities are separated by the palate. The anterior, rigid portion is called the hard palate, and the posterior fleshy part is called the soft palate. The mouth and nose serve as secondary respiratory structures.. Pharynx. The pharynx, or throat, serves both the respiratory and digestive systems and aids in speech. It has a mucous membrane lining that traps microscopic particles in the air and aids in adjusting temperature and humidifying inspired (inhaled) air. The pharynx connects with the mouth and nasal chambers posteriorly. According to its location, the pharynx is referred to as the ...

Nasal irrigation with Nasaline or the Neti Pot involves flooding the nasal cavity with warm saline solution.The goal is to clear out excess mucus and particulates and moisturize the nasal cavity.
This is a small, delicate bone that projects from the lateral wall of the nasal cavity. The projection is scroll-like, arching inferiorly and laterally from the lateral wall. It helps subdivide the nasal cavity into the inferior meatus below and superior meatus above. The medial surface of the bone is convex and furrowed by many longitudinal grooves that transport vessels under the thick nasal mucosa covering its surface. The lateral surface of the bone is concave and forms most of the superior and medial boundary of the inferior nasal meatus. The inferior border of the bone has a rough, spongy appearance. This surface has a thick mucosal covering in life. Superiorly the bone forms an articular border with four bones. Three irregular processes project from this border to articulate with neighboring bones ...
In the present study, we have assessed the S. aureus localization within vestibulum nasi in healthy individuals. By using a confocal scanning laser microscopy approach, we found that S. aureus is localised in both the upper and lower layers of epidermis within the nasal epithelium of healthy individuals. We also observed intracellular localization of S. aureus in the different layers of epidermis.. As expected, we identified the majority of S. aureus in the stratum corneum. In artificially colonized cotton rats, localization of S. aureus has been shown in the stratum corneum of intranasal squamous epithelium [24] where S. aureus appeared as single cells or diplococci, a finding that is corroborated by our study. This is also in accordance with other studies showing that adherence of S. aureus to nasal cells is directly related with the age of the epithelial cells. The most differentiated cells bind most S. aureus, while the youngest cells (less differentiated keratinocytes in the lower epidermis ...

The nasal skeleton contains the nasal cavity. Lined by a sheet of respiratory cells (epithelium), the vestibule is the first part of the nasal cavity just on the inside of the nostrils. Mucus-secreting cells are found in the respiratory region. The olfactory region is what allows you to smell. The olfactory system has millions of receptors that help the brain interpret around 10,000 or so different smells. Above the soft palate at the back of your nose is the nasopharynx, which connects your nose to your mouth. A tube connects the nasopharynx to the middle ear.. ...
7. The best air filter in this world is human nose. Human nostrils are lined up with hair responsible for blocking germs and dust. Grooves in nasal cavity make air swirl like stream currents. This is when the inhaled hair is moistened and warmed so that the sensitive tissues of the lungs can be protected. It is during this filtration process that the mucus lining of the nasal cavity captures cold viruses and pollen which cannot be stopped by hair in nostrils ...

Though not a primary part of the human respiratory system, its functions include serving as the secondary passage for air to enter and exit the respiratory tract during inhalation and exhalation [14]. Function of the Mouth During breathing, the mouth acts as the secondary entrance for air to get into the respiratory tract. the mouth is the beginning of the digestive system -- digestion starts there before you even take the first bite of a meal. The nose is a structure of the face made of cartilage, bone, muscle, and skin that supports and protects the anterior portion of the nasal cavity. Breathing starts when you inhale air into your nose or mouth. However, since the oral cavity is much shorter than the nasal cavity, and lacks the mucus lining and cilia present in the latter, it does not moisten and purify the inhaled air [15]. In this post, we learn about the various parts of our respiratory system, its functions, and some of the common respiratory … all use mouth as a complementary organ. ...

Pharmacological treatment of disorders affecting the central nervous system (CNS) is a complex task. Different parameters may negatively influence effective targeting of the CNS and drug compliance, for example, poor brain-blood barrier (BBB) permeability, patient forgetfulness or neglect, and lack of collaboration between caregivers and patients. Pharmaceutical science is constantly looking for new administration strategies for efficient drug delivery to the CNS that could obviate these problems. Drugs can reach the brain through the skin, nasal cavity and oral cavity, and while effective transport of drugs from skin and nasal cavity to the CNS has been documented, these studies did not stimulate the introduction of a substantial number of new drug formulations to treat CNS disorders. Nasal drug delivery, generally used to administer locally acting molecules, is not common for systemic administration, although the possibility and importance of such systemic administration is suggested by ...

TUESDAY, June 9, 2020 (HealthDay News) -- Scientists studying the SARS-CoV-2 coronavirus -- which causes COVID-19 -- believe theyve discovered why face masks might help limit transmission of the virus. The virus tends to first infect the nasal cavity, replicating less well in the lower respiratory tract, University of North Carolina (UNC) researchers found. However, sometimes its sucked into the lungs, where it can cause serious consequences, including fatal pneumonia. If the nose is the dominant initial site from which lung infections are seeded, then the widespread use of masks to protect the nasal passages, as well as any therapeutic strategies that reduce virus in the nose, such as nasal irrigation or antiviral nasal sprays, could be beneficial, study co-author Dr. Richard Boucher said in a university news release.. Boucher is a professor of medicine and director of the UNC School of Medicines Lung Institute. The study reveals new information about disease progression and severity ...
