Transmission of sound waves through vibration of bones in the SKULL to the inner ear (COCHLEA). By using bone conduction stimulation and by bypassing any OUTER EAR or MIDDLE EAR abnormalities, hearing thresholds of the cochlea can be determined. Bone conduction hearing differs from normal hearing which is based on air conduction stimulation via the EAR CANAL and the TYMPANIC MEMBRANE.
A mobile chain of three small bones (INCUS; MALLEUS; STAPES) in the TYMPANIC CAVITY between the TYMPANIC MEMBRANE and the oval window on the wall of INNER EAR. Sound waves are converted to vibration by the tympanic membrane then transmitted via these ear ossicles to the inner ear.
The lower chamber of the COCHLEA, extending from the round window to the helicotrema (the opening at the apex that connects the PERILYMPH-filled spaces of scala tympani and SCALA VESTIBULI).
Hearing loss due to interference with the mechanical reception or amplification of sound to the COCHLEA. The interference is in the outer or middle ear involving the EAR CANAL; TYMPANIC MEMBRANE; or EAR OSSICLES.
The space and structures directly internal to the TYMPANIC MEMBRANE and external to the inner ear (LABYRINTH). Its major components include the AUDITORY OSSICLES and the EUSTACHIAN TUBE that connects the cavity of middle ear (tympanic cavity) to the upper part of the throat.
The propagation of the NERVE IMPULSE along the nerve away from the site of an excitation stimulus.
A specialized CONNECTIVE TISSUE that is the main constituent of the SKELETON. The principle cellular component of bone is comprised of OSTEOBLASTS; OSTEOCYTES; and OSTEOCLASTS, while FIBRILLAR COLLAGENS and hydroxyapatite crystals form the BONE MATRIX.
Wearable sound-amplifying devices that are intended to compensate for impaired hearing. These generic devices include air-conduction hearing aids and bone-conduction hearing aids. (UMDNS, 1999)
Measurement of hearing based on the use of pure tones of various frequencies and intensities as auditory stimuli.
An impulse-conducting system composed of modified cardiac muscle, having the power of spontaneous rhythmicity and conduction more highly developed than the rest of the heart.
The audibility limit of discriminating sound intensity and pitch.
The continuous turnover of BONE MATRIX and mineral that involves first an increase in BONE RESORPTION (osteoclastic activity) and later, reactive BONE FORMATION (osteoblastic activity). The process of bone remodeling takes place in the adult skeleton at discrete foci. The process ensures the mechanical integrity of the skeleton throughout life and plays an important role in calcium HOMEOSTASIS. An imbalance in the regulation of bone remodeling's two contrasting events, bone resorption and bone formation, results in many of the metabolic bone diseases, such as OSTEOPOROSIS.
The amount of mineral per square centimeter of BONE. This is the definition used in clinical practice. Actual bone density would be expressed in grams per milliliter. It is most frequently measured by X-RAY ABSORPTIOMETRY or TOMOGRAPHY, X RAY COMPUTED. Bone density is an important predictor for OSTEOPOROSIS.
Bone loss due to osteoclastic activity.
The soft tissue filling the cavities of bones. Bone marrow exists in two types, yellow and red. Yellow marrow is found in the large cavities of large bones and consists mostly of fat cells and a few primitive blood cells. Red marrow is a hematopoietic tissue and is the site of production of erythrocytes and granular leukocytes. Bone marrow is made up of a framework of connective tissue containing branching fibers with the frame being filled with marrow cells.

Ear and hearing in Sphenodon punctatus. (1/67)

Observations on Sphenodon punctatus have revealed new features of the anatomy of the ear,and measurements in a living specimen by means of cochlear potentials show the form and level of this ear's performance in sound reception. For an animal lacking an external ear opening and a functional tympanic membrane, the sensitivity of from 100-900 Hz is surprisingly good in low tones with peak response around 200-400 Hz. The inner ear is well developed, with a tectorial membrane connected to a tectorial plate that extends throughout the cochlea. The best region of sensitivity agrees well with the main frequency components of the animal's vocalizations.  (+info)

Isolating the auditory system from acoustic noise during functional magnetic resonance imaging: examination of noise conduction through the ear canal, head, and body. (2/67)

Approaches were examined for reducing acoustic noise levels heard by subjects during functional magnetic resonance imaging (fMRI), a technique for localizing brain activation in humans. Specifically, it was examined whether a device for isolating the head and ear canal from sound (a "helmet") could add to the isolation provided by conventional hearing protection devices (i.e., earmuffs and earplugs). Both subjective attenuation (the difference in hearing threshold with versus without isolation devices in place) and objective attenuation (difference in ear-canal sound pressure) were measured. In the frequency range of the most intense fMRI noise (1-1.4 kHz), a helmet, earmuffs, and earplugs used together attenuated perceived sound by 55-63 dB, whereas the attenuation provided by the conventional devices alone was substantially less: 30-37 dB for earmuffs, 25-28 dB for earplugs, and 39-41 dB for earmuffs and earplugs used together. The data enabled the clarification of the relative importance of ear canal, head, and body conduction routes to the cochlea under different conditions: At low frequencies (< or =500 Hz), the ear canal was the dominant route of sound conduction to the cochlea for all of the device combinations considered. At higher frequencies (>500 Hz), the ear canal was the dominant route when either earmuffs or earplugs were worn. However, the dominant route of sound conduction was through the head when both earmuffs and earplugs were worn, through both ear canal and body when a helmet and earmuffs were worn, and through the body when a helmet, earmuffs, and earplugs were worn. It is estimated that a helmet, earmuffs, and earplugs together will reduce the most intense fMRI noise levels experienced by a subject to 60-65 dB SPL. Even greater reductions in noise should be achievable by isolating the body from the surrounding noise field.  (+info)

Nievergelt-Pearlman syndrome with impairment of hearing. Report of three cases in a family. (3/67)

Three cases of the Nievergelt-Pearlman syndrome occurring in a family are presented. In addition to the major features of the syndrome (symphalangism, carpal fusion, atypical club foot with massive tarsal fusion, and congenital dislocation of the head of the radius), all three patients exhibited conductive deafness, which had not been recorded in previous reports. The clinical findings strongly suggested that the loss of hearing was due to fusion of the ossicles of the middle ear.  (+info)

Inner ear damage in children due to noise exposure from toy cap pistols and firecrackers: a retrospective review of 53 cases. (4/67)

This retrospective study presents the findings of inner ear damage documented in 53 children exposed to impulsive sound emitted by toy weapons and firecrackers. There were 49 boys and four girls aged between four and fourteen years. Thirty-nine children were affected unilaterally while fourteen had bilateral hearing loss (total of 67 ears). Most of the hearing loss (>70%) was sensorineural high frequency hearing loss, while only nine out of the 67 injured ears had sensorineural mid frequency hearing loss. Seven children sustained a traumatic ear drum perforation. Dizziness or tinnitus was reported by twenty children, with pathological ENG findings in four of them. This paper re-emphasizes the possibility of inner ear damage in children from exposure to noisy toys.  (+info)

Vestibular activation by bone conducted sound. (5/67)

OBJECTIVE: To examine the properties and potential clinical uses of myogenic potentials to bone conducted sound. METHODS: Myogenic potentials were recorded from normal volunteers, using bone conducted tone bursts of 7 ms duration and 250-2000 Hz frequencies delivered over the mastoid processes by a B 71 clinical bone vibrator. Biphasic positive-negative (p1n1) responses were recorded from both sternocleidomastoid (SCM) muscles using averaged unrectified EMG. The best location for stimulus delivery, optimum stimulus frequency, stimulus thresholds, and the effect of aging on evoked response amplitudes and thresholds were systematically examined. Subjects with specific lesions were studied. Vestibular evoked myogenic potentials (VEMP) to air conducted 0.1 ms clicks, 7 ms/250-2000 Hz tones, and forehead taps were measured for comparison. RESULTS: Bone conducted sound evoked short latency p1n1 responses in both SCM muscles. Ipsilateral responses occurred earlier and were usually larger. Mean (SD) p1 and n1 latencies were 13.6 (1.8) and 22.3 (1.2) ms ipsilaterally and 14.9 (2.1) and 23.7 (2.7) ms contralaterally. Stimuli of 250 Hz delivered over the mastoid process, posterosuperior to the external acoustic meatus, yielded the largest amplitude responses. Like VEMP in response to air conducted clicks and tones, p1n1 responses were absent ipsilaterally in subjects with selective vestibular neurectomy and preserved in those with severe sensorineural hearing loss. However, p1n1 responses were preserved in conductive hearing loss, whereas VEMP to air conducted sound were abolished or attenuated. Bone conducted response thresholds were 97.5 (3.9) dB SPL/30.5 dB HL, significantly lower than thresholds to air conducted clicks (131.7 (4.9) dB SPL/86.7 dB HL) and tones (114.0 (5.3) dB SPL/106 dB HL). CONCLUSIONS: Bone conducted sound evokes p1n1 responses (bone conducted VEMP) which are a useful measure of vestibular function, especially in the presence of conductive hearing loss. For a given perceptual intensity, bone conducted sound activates the vestibular apparatus more effectively than air conducted sound.  (+info)

Middle ear dynamics in response to seismic stimuli in the Cape golden mole (Chrysochloris asiatica). (6/67)

The hypertrophied malleus in the middle ear of some golden moles has been assumed to be an adaptation for sensing substrate vibrations by inertial bone conduction, but this has never been conclusively demonstrated. The Cape golden mole (Chrysochloris asiatica) exhibits this anatomical specialization, and the dynamic properties of its middle ear response to vibrations were the subjects of this study. Detailed three-dimensional middle ear anatomy was obtained by x-ray microcomputed tomography (muCT) at a resolution of 12 microm. The ossicular chain exhibits large malleus mass, selective reduction of stiffness and displacement of the center of mass from the suspension points, all favoring low-frequency tuning of the middle ear response. Orientation of the stapes relative to the ossicular chain and the structure of the stapes footplate enable transmission of substrate vibrations arriving from multiple directions to the inner ear. With the long axes of the mallei aligned parallel to the surface, the animal's head was stimulated by a vibration exciter in the vertical and lateral directions over a frequency range from 10 to 600 Hz. The ossicular chain was shown to respond to both vertical and lateral vibrations. Resonant frequencies were found between 71 and 200 Hz and did not differ significantly between the two stimulation directions. Below resonance, the ossicular chain moves in phase with the skull. Near resonance and above, the malleus moves at a significantly larger mean amplitude (5.8+/-2.8 dB) in response to lateral vs vertical stimuli and is 180 degrees out of phase with the skull in both cases. A concise summary of the propagation characteristics of both seismic body (P-waves) and surface (R-waves) is provided. Potential mechanisms by which the animal might exploit the differential response of the ossicular chain to vertical and lateral excitation are discussed in relation to the properties of surface seismic waves.  (+info)

Craniocentric body-sway responses to 500 Hz bone-conducted tones in man. (7/67)

Whole-body responses evoked by bone-conducted sound, a stimulus known to activate vestibular afferents, were recorded in standing subjects deprived of vision. With the head facing forward, unilateral mastoid vibration (500 Hz, 2 s, 136 dB force level) produced an oblique body sway with a consistent lateral component away from the stimulated ear and an average forward component. The side of stimulation had a powerful influence on the direction but not the magnitude of sway. Individuals' mean response directions were significantly clustered between subjects, as well as within subjects for 12 of 16 subjects when tested on five occasions. Single trial analysis did not reveal any habituation of the response. To investigate whether muscle spindle activation might be responsible for the response, vibration was applied directly over posterior and anterior neck muscles and tendons. This generally produced responses that were smaller and with different direction characteristics than with mastoid vibration. In contrast, stimulation over the temporal fossa produced responses similar in magnitude and direction to mastoid stimulation. When the head was turned in yaw to face in different directions the sway response changed direction by the same amount but with no change in magnitude, suggesting response organization in a craniocentric reference frame. Whole-body sway evoked by 500 Hz vibration delivered over sites close to the ear is thus likely to represent a vestibular-evoked balance response. When compared with sway responses evoked by 500 Hz vibration of the left temporal fossa, responses to 1 mA left cathodal galvanic vestibular stimulation were of similar magnitude, yet significantly different in direction, suggesting differences in the end organ afferents activated by these two stimuli. This may enable investigation of previously inaccessible aspects of vestibular function in intact freely behaving human subjects.  (+info)

Superior Canal Dehiscence Syndrome. (8/67)

The Superior Canal Dehiscence Syndrome (SCDS) was first reported by Minor at. Al. (1998), and has been characterized by vertigo and vertical-torsional eye movements related to loud sounds or stimuli that change middle ear or intracranial pressure. Hearing loss, for the most part with conductive patterns on audiometry, may be present in this syndrome. We performed a literature survey in order to to present symptoms, signs, diagnostic and therapeutic approaches to the SCDS, also aiming at stressing the great importance of including this syndrome among the tractable cause of vertigo. We should emphasize that this is a recent issue, still unknown by some specialists. The Correct SCDS diagnosis, besides enabling patient treatment, precludes misdiagnosis and inadequate therapeutic approaches.  (+info)

Bone conduction is a type of hearing mechanism that involves the transmission of sound vibrations directly to the inner ear through the bones of the skull, bypassing the outer and middle ears. This occurs when sound waves cause the bones in the skull to vibrate, stimulating the cochlea (the spiral cavity of the inner ear) and its hair cells, which convert the mechanical energy of the vibrations into electrical signals that are sent to the brain and interpreted as sound.

Bone conduction is a natural part of the hearing process in humans, but it can also be used artificially through the use of bone-conduction devices, such as hearing aids or headphones, which transmit sound vibrations directly to the skull. This type of transmission can provide improved hearing for individuals with conductive hearing loss, mixed hearing loss, or single-sided deafness, as it bypasses damaged or obstructed outer and middle ears.

The ear ossicles are the three smallest bones in the human body, which are located in the middle ear. They play a crucial role in the process of hearing by transmitting and amplifying sound vibrations from the eardrum to the inner ear. The three ear ossicles are:

1. Malleus (hammer): The largest of the three bones, it is shaped like a hammer and connects to the eardrum.
2. Incus (anvil): The middle-sized bone, it looks like an anvil and connects the malleus to the stapes.
3. Stapes (stirrup): The smallest and lightest bone in the human body, it resembles a stirrup and transmits vibrations from the incus to the inner ear.

Together, these tiny bones work to efficiently transfer sound waves from the air to the fluid-filled cochlea of the inner ear, enabling us to hear.

The Scala Tympani is a part of the inner ear's bony labyrinth, specifically within the cochlea. It is one of the two channels (the other being the Scala Vestibuli) that make up the bony duct of the cochlea, through which sound waves are transmitted to the inner ear.

The Scala Tympani starts at the round window, which is a membrane-covered opening located on the cochlea's outer wall. It runs parallel to the Scala Vestibuli and connects with it at the helicotrema, a small opening at the apex or tip of the cochlea.

When sound waves reach the inner ear, they cause vibrations in the fluid-filled Scala Tympani and Scala Vestibuli, which stimulate hair cells within the organ of Corti, leading to the conversion of mechanical energy into electrical signals that are then transmitted to the brain via the auditory nerve.

It's important to note that any damage or dysfunction in the Scala Tympani or other parts of the inner ear can lead to hearing loss or other auditory disorders.

Conductive hearing loss is a type of hearing loss that occurs when there is a problem with the outer or middle ear. Sound waves are not able to transmit efficiently through the ear canal to the eardrum and the small bones in the middle ear, resulting in a reduction of sound that reaches the inner ear. Causes of conductive hearing loss may include earwax buildup, fluid in the middle ear, a middle ear infection, a hole in the eardrum, or problems with the tiny bones in the middle ear. This type of hearing loss can often be treated through medical intervention or surgery.

The middle ear is the middle of the three parts of the ear, located between the outer ear and inner ear. It contains three small bones called ossicles (the malleus, incus, and stapes) that transmit and amplify sound vibrations from the eardrum to the inner ear. The middle ear also contains the Eustachian tube, which helps regulate air pressure in the middle ear and protects against infection by allowing fluid to drain from the middle ear into the back of the throat.

Neural conduction is the process by which electrical signals, known as action potentials, are transmitted along the axon of a neuron (nerve cell) to transmit information between different parts of the nervous system. This electrical impulse is generated by the movement of ions across the neuronal membrane, and it propagates down the length of the axon until it reaches the synapse, where it can then stimulate the release of neurotransmitters to communicate with other neurons or target cells. The speed of neural conduction can vary depending on factors such as the diameter of the axon, the presence of myelin sheaths (which act as insulation and allow for faster conduction), and the temperature of the environment.

"Bone" is the hard, dense connective tissue that makes up the skeleton of vertebrate animals. It provides support and protection for the body's internal organs, and serves as a attachment site for muscles, tendons, and ligaments. Bone is composed of cells called osteoblasts and osteoclasts, which are responsible for bone formation and resorption, respectively, and an extracellular matrix made up of collagen fibers and mineral crystals.

Bones can be classified into two main types: compact bone and spongy bone. Compact bone is dense and hard, and makes up the outer layer of all bones and the shafts of long bones. Spongy bone is less dense and contains large spaces, and makes up the ends of long bones and the interior of flat and irregular bones.

The human body has 206 bones in total. They can be further classified into five categories based on their shape: long bones, short bones, flat bones, irregular bones, and sesamoid bones.

Hearing aids are electronic devices designed to improve hearing and speech comprehension for individuals with hearing loss. They consist of a microphone, an amplifier, a speaker, and a battery. The microphone picks up sounds from the environment, the amplifier increases the volume of these sounds, and the speaker sends the amplified sound into the ear. Modern hearing aids often include additional features such as noise reduction, directional microphones, and wireless connectivity to smartphones or other devices. They are programmed to meet the specific needs of the user's hearing loss and can be adjusted for comfort and effectiveness. Hearing aids are available in various styles, including behind-the-ear (BTE), receiver-in-canal (RIC), in-the-ear (ITE), and completely-in-canal (CIC).

Pure-tone audiometry is a hearing test that measures a person's ability to hear different sounds, pitches, or frequencies. During the test, pure tones are presented to the patient through headphones or ear inserts, and the patient is asked to indicate each time they hear the sound by raising their hand, pressing a button, or responding verbally.

The softest sound that the person can hear at each frequency is recorded as the hearing threshold, and a graph called an audiogram is created to show the results. The audiogram provides information about the type and degree of hearing loss in each ear. Pure-tone audiometry is a standard hearing test used to diagnose and monitor hearing disorders.

The heart conduction system is a group of specialized cardiac muscle cells that generate and conduct electrical impulses to coordinate the contraction of the heart chambers. The main components of the heart conduction system include:

1. Sinoatrial (SA) node: Also known as the sinus node, it is located in the right atrium near the entrance of the superior vena cava and functions as the primary pacemaker of the heart. It sets the heart rate by generating electrical impulses at regular intervals.
2. Atrioventricular (AV) node: Located in the interatrial septum, near the opening of the coronary sinus, it serves as a relay station for electrical signals between the atria and ventricles. The AV node delays the transmission of impulses to allow the atria to contract before the ventricles.
3. Bundle of His: A bundle of specialized cardiac muscle fibers that conducts electrical impulses from the AV node to the ventricles. It divides into two main branches, the right and left bundle branches, which further divide into smaller Purkinje fibers.
4. Right and left bundle branches: These are extensions of the Bundle of His that transmit electrical impulses to the respective right and left ventricular myocardium. They consist of specialized conducting tissue with large diameters and minimal resistance, allowing for rapid conduction of electrical signals.
5. Purkinje fibers: Fine, branching fibers that arise from the bundle branches and spread throughout the ventricular myocardium. They are responsible for transmitting electrical impulses to the working cardiac muscle cells, triggering coordinated ventricular contraction.

In summary, the heart conduction system is a complex network of specialized muscle cells responsible for generating and conducting electrical signals that coordinate the contraction of the atria and ventricles, ensuring efficient blood flow throughout the body.

The auditory threshold is the minimum sound intensity or loudness level that a person can detect 50% of the time, for a given tone frequency. It is typically measured in decibels (dB) and represents the quietest sound that a person can hear. The auditory threshold can be affected by various factors such as age, exposure to noise, and certain medical conditions. Hearing tests, such as pure-tone audiometry, are used to measure an individual's auditory thresholds for different frequencies.

Bone remodeling is the normal and continuous process by which bone tissue is removed from the skeleton (a process called resorption) and new bone tissue is formed (a process called formation). This ongoing cycle allows bones to repair microdamage, adjust their size and shape in response to mechanical stress, and maintain mineral homeostasis. The cells responsible for bone resorption are osteoclasts, while the cells responsible for bone formation are osteoblasts. These two cell types work together to maintain the structural integrity and health of bones throughout an individual's life.

During bone remodeling, the process can be divided into several stages:

1. Activation: The initiation of bone remodeling is triggered by various factors such as microdamage, hormonal changes, or mechanical stress. This leads to the recruitment and activation of osteoclast precursor cells.
2. Resorption: Osteoclasts attach to the bone surface and create a sealed compartment called a resorption lacuna. They then secrete acid and enzymes that dissolve and digest the mineralized matrix, creating pits or cavities on the bone surface. This process helps remove old or damaged bone tissue and releases calcium and phosphate ions into the bloodstream.
3. Reversal: After resorption is complete, the osteoclasts undergo apoptosis (programmed cell death), and mononuclear cells called reversal cells appear on the resorbed surface. These cells prepare the bone surface for the next stage by cleaning up debris and releasing signals that attract osteoblast precursors.
4. Formation: Osteoblasts, derived from mesenchymal stem cells, migrate to the resorbed surface and begin producing a new organic matrix called osteoid. As the osteoid mineralizes, it forms a hard, calcified structure that gradually replaces the resorbed bone tissue. The osteoblasts may become embedded within this newly formed bone as they differentiate into osteocytes, which are mature bone cells responsible for maintaining bone homeostasis and responding to mechanical stress.
5. Mineralization: Over time, the newly formed bone continues to mineralize, becoming stronger and more dense. This process helps maintain the structural integrity of the skeleton and ensures adequate calcium storage.

Throughout this continuous cycle of bone remodeling, hormones, growth factors, and mechanical stress play crucial roles in regulating the balance between resorption and formation. Disruptions to this delicate equilibrium can lead to various bone diseases, such as osteoporosis, where excessive resorption results in weakened bones and increased fracture risk.

Bone density refers to the amount of bone mineral content (usually measured in grams) in a given volume of bone (usually measured in cubic centimeters). It is often used as an indicator of bone strength and fracture risk. Bone density is typically measured using dual-energy X-ray absorptiometry (DXA) scans, which provide a T-score that compares the patient's bone density to that of a young adult reference population. A T-score of -1 or above is considered normal, while a T-score between -1 and -2.5 indicates osteopenia (low bone mass), and a T-score below -2.5 indicates osteoporosis (porous bones). Regular exercise, adequate calcium and vitamin D intake, and medication (if necessary) can help maintain or improve bone density and prevent fractures.

Bone resorption is the process by which bone tissue is broken down and absorbed into the body. It is a normal part of bone remodeling, in which old or damaged bone tissue is removed and new tissue is formed. However, excessive bone resorption can lead to conditions such as osteoporosis, in which bones become weak and fragile due to a loss of density. This process is carried out by cells called osteoclasts, which break down the bone tissue and release minerals such as calcium into the bloodstream.

Bone marrow is the spongy tissue found inside certain bones in the body, such as the hips, thighs, and vertebrae. It is responsible for producing blood-forming cells, including red blood cells, white blood cells, and platelets. There are two types of bone marrow: red marrow, which is involved in blood cell production, and yellow marrow, which contains fatty tissue.

Red bone marrow contains hematopoietic stem cells, which can differentiate into various types of blood cells. These stem cells continuously divide and mature to produce new blood cells that are released into the circulation. Red blood cells carry oxygen throughout the body, white blood cells help fight infections, and platelets play a crucial role in blood clotting.

Bone marrow also serves as a site for immune cell development and maturation. It contains various types of immune cells, such as lymphocytes, macrophages, and dendritic cells, which help protect the body against infections and diseases.

Abnormalities in bone marrow function can lead to several medical conditions, including anemia, leukopenia, thrombocytopenia, and various types of cancer, such as leukemia and multiple myeloma. Bone marrow aspiration and biopsy are common diagnostic procedures used to evaluate bone marrow health and function.
