Cranial nerve development requires co-ordinated Shh and canonical Wnt signaling[1] Cranial nerves govern sensory and motor information exchange between the brain and tissues of the head and neck. The cranial nerves are derived from two specialized populations of cells, cranial neural crest cells and ectodermal placode cells. Defects in either cell type can result in cranial nerve developmental defects. Although several signaling pathways are known to regulate cranial nerve formation our understanding of how intercellular signaling between neural crest cells and placode cells is coordinated during cranial ganglia morphogenesis is poorly understood. Sonic Hedgehog (Shh) signaling is one key pathway that regulates multiple aspects of craniofacial development, but whether it co-ordinates cranial neural crest cell and placodal cell interactions during cranial ganglia formation remains unclear. In this study we examined a new Patched1 (Ptch1) loss-of-function mouse mutant and characterized the role ...

The present study examined the role of branchial and orobranchial O2 chemoreceptors in the cardiorespiratory responses, aquatic surface respiration (ASR), and the development of inferior lip swelling in tambaqui during prolonged (6 h) exposure to hypoxia. Intact fish (control) and three groups of denervated fish (bilateral denervation of cranial nerves IX+X (to the gills), of cranial nerves V+VII (to the orobranchial cavity) or of cranial nerves V alone), were exposed to severe hypoxia (PwO2=10 mmHg) for 360 min. Respiratory frequency (fr) and heart rate (fh) were recorded simultaneously with ASR. Intact (control) fish increased fr, ventilation amplitude (VAMP) and developed hypoxic bradycardia in the first 60 min of hypoxia. The bradycardia, however, abated progressively and had returned to normoxic levels by the last hour of exposure to hypoxia. The changes in respiratory frequency and the hypoxic bradycardia were eliminated by denervation of cranial nerves IX and X but were not affected by ...
PURPOSE: We report our experience with the use of maternally derived serum eye drops as adjunctive treatment in the management of pediatric persistent corneal epithelial defects. METHODS: Five eyes of 4 patients were identified in a retrospective review of pediatric patients with persistent corneal epithelial defects who received maternal serum drops. Diagnoses associated with the defects comprised pontine tegmental cap dysplasia with bilateral cranial nerve V1, V2, V3, and VII palsies; pontine tegmental cap dysplasia with left cranial nerve V1, VII, and VIII palsies; traumatic left cranial nerve II, V1, V2, and VI palsies due to a basilar skull fracture; and Stevens-Johnson syndrome with ocular involvement ...
Headaches can arise from many different causes. A partial list includes stress, lack of sleep, allergies, neck trauma (particularly sports injuries and car accidents), and more. In some cases, the cause may be unknown. A unique common denominator of headaches has to do with cervical spine anatomy, in particular the upper part of the neck. There are seven cervical vertebrae, and the top three (C1-3) give rise to three nerves that travel into the head. These nerves also share a pain nucleus with the trigeminal nerve (cranial nerve V), which can route pain signals to the brain. Depending on which nerve is most irritated, the location of the headache can vary. For example, C2-the greater occipital nerve-travels up the back of the head to the top. From there, it can communicate with another nerve (cranial nerve V or the trigeminal nerve), which can refer pain to the forehead and/or behind the eye. When C1-the lesser occipital nerve-is irritated, pain travels to the back of the head, while irritation ...

Structure. Development. During embryonic development, the embryonic metencephalon develops from the rhombencephalon and gives rise to two structures: the pons and the cerebellum. The alar plate produces sensory neuroblasts, which will give rise to the solitary nucleus and its special visceral afferent (SVA) column; the cochlear and vestibular nuclei, which form the special somatic afferent (SSA) fibers of the vestibulocochlear nerve, the spinal and principal trigeminal nerve nuclei, which form the general somatic afferent column (GSA) of the trigeminal nerve, and the pontine nuclei which relays to the cerebellum.. Basal plate neuroblasts give rise to the abducens nucleus,which forms the general somatic efferent fibers (GSE); the facial and motor trigeminal nuclei, which form the special visceral efferent (SVE) column, and the superior salivatory nucleus, which forms the general visceral efferent fibers of the facial nerve..

Cranial nerves are generally named according to their structure or function. For example, the olfactory nerve (I) supplies smell, and the facial nerve (VII) supplies motor innervation to the face. Because Latin was the lingua franca (common language) of the study of anatomy when the nerves were first documented, recorded, and discussed, many nerves maintain Latin or Greek names, including the trochlear nerve (IV), named according to its structure, as it supplies a muscle that attaches to a pulley (Greek: trochlea). The trigeminal nerve (V) is named in accordance with its three components (Latin: trigeminus meaning triplets),[6] and the vagus nerve (X) is named for its wandering course (Latin: vagus).[7] Cranial nerves are numbered based on their rostral-caudal (front-back) position,[1] when viewing the brain. If the brain is carefully removed from the skull the nerves are typically visible in their numeric order, with the exception of the last, CN XII, which appears to emerge rostrally to ...

The developing vertebrate hindbrain consists of segmental units known as rhombomeres. Hindbrain neuroectoderm expresses 3′ Hox 1 and 2 cluster genes in characteristic patterns whose anterior limit of expression coincides with rhombomere boundaries. One particular Hox gene, referred to as Ghox 2.9, is initially expressed throughout the hindbrain up to the anterior border of rhombomere 4 (r4). Later, Ghox 2.9 is strongly upregulated in r4 and Ghox 2.9 protein is found in all neuroectodermal cells of r4 and in the hyoid crest cell population derived from this rhombomere. Using a polyclonal antibody, Ghox 2.9 was immunolocalized after transplanting r4 within the hindbrain. Wherever r4 was transplanted, Ghox 2.9 expression was cell-autonomous, both in the neuroectoderm of the graft and in the hyoid crest cell population originating from the graft. In all vertebrates, rhombomeres and cranial nerves (nerves V, VII+VIII, IX, X) exhibit a stereotypic relationship: nerve V arises at the level of r2, ...
Thus, both a conscious and an unconscious person can survive longer without oxygen under water than in a comparable situation on dry land. Children tend to survive longer than adults when deprived of oxygen underwater.. When the face is submerged, receptors that are sensitive to water within the nasal cavity and other areas of the face supplied by cranial nerve V (trigeminal) relay the information to the brain and then innervate cranial nerve X, which is part of the autonomic nervous system. This causes bradycardia and peripheral vasoconstriction. Blood is removed from the limbs and all organs but the heart and the brain, creating a heart-brain circuit and allowing the mammal to conserve oxygen.. In humans, the mammalian diving reflex is not induced when limbs are introduced to cold water. Mild bradycardia is caused by the subject holding his breath without submerging the face within water. When breathing with face submerged this causes a diving reflex which increases proportionally to ...
Cranial Nerve 1- Olfaction This patient has difficulty identifying the smells presented. Loss of smell is anosmia. The most common cause is a cold (as in this patient) or nasal allergies. Other causes include trauma or a meningioma affecting the olfactory tracts. Anosmia is also seen in Kallman syndrome because of agenesis of the olfactory bulbs. Cranial Nerve 2- Visual acuity This patientâs visual acuity is being tested with a Rosenbaum chart. First the left eye is tested, then the right eye. He is tested with his glasses on so this represents corrected visual acuity. He has 20/70 vision in the left eye and 20/40 in the right. His decreased visual acuity is from optic nerve damage. Cranial Nerve II- Visual field The patients visual fields are being tested with gross confrontation. A right sided visual field deficit for both eyes is shown. This is a right hemianopia from a lesion behind the optic chiasm involving the left optic tract, radiation or striate cortex. Cranial Nerve II- Fundoscopy ...

The corneal reflex test (blink test) examines the reflex pathway involving cranial nerves V and VII. Classically the provider lightly touches a wisp of cotton on the patients cornea. This foreign body sensation should cause the patient to reflexively blink.. This maneuver always makes me a little worried about causing a corneal abrasion, especially if you are examining a very somnolent patient. You are wondering - Is there no blinking because youre not touching the cornea hard enough? You apply harder pressure but still no blink. You repeat the test and now the patient finally blinks. Thats 3 times youve just scraped against the cornea.. Whats an alternative approach?. ...

Introduction Examination of the cranial nerves allows one to view the brainstem all the way from its rostral to caudal extent. The brainstem can be divided into three levels, the midbrain, the pons and the medulla. The cranial nerves for each of these are: 2 for the midbrain (CN 3 & 4), 4 for the pons (CN 5-8), and 4 for the medulla (CN 9-12). It is important to remember that cranial nerves never cross (except for one exception, the 4th CN) and clinical findings are always on the same side as the cranial nerve involved. Cranial nerve findings when combined with long tract findings (corticospinal and somatosensory) are powerful for localizing lesions in the brainstem. Cranial Nerve 1 Olfaction is the only sensory modality with direct access to cerebral cortex without going through the thalamus. The olfactory tracts project mainly to the uncus of the temporal lobes. Cranial Nerve 2 This cranial nerve has important localizing value because of its x axis course from the eye to the occipital ...
The next time youre trying to remember the locations and functions of the cranial nerves, picture this drawing. All twelve cranial nerves are represented, though some may be a little harder to spot than others. For example, the shoulders are formed by the number 11 because cranial nerve XI controls neck and shoulder movement. If you immediately recognize that the sides of the face and the top of the head are formed by the number 7, youre well on your way to using this memory device..

Eye movements depend on correct patterns of connectivity between cranial motor axons and the extraocular muscles.

We have recently shown that mutations in the Chimaerin-1 gene encoding the signaling protein α2-chimaerin (α2-chn) perturb axon guidance in the ocular mot ...
Now, take a look at what I call cranial nerve maps. These are icons of cranial nerves, their branches, what they supply and what foramina they use. Sensory is yellow and motor is red. Solid red is for skeletal muscle. Dashed red is for parasympathetic fibers. You sort of have to memorize which nerves have motor or sensory or both modalities, then consider what part of the head and neck is involved with each nerve. For example, when you look at the olfactory road map, you will see that it is yellow which means it is purely sensory. Then you consider what kind of sensation of picked up in the periphery which, in this case, is smell. The smell impulses then go back to the central nervous system. If there is red included in the map, that means that something will receive efferent fibers and will either contract or secrete. The impulse starts out in the central nervous system and passes out to a muscle or gland. ...
The cranial nerves are a set of 12 nerves which emerge directly from the brain. The names of the cranial nerves relate to their function and they are also numerically identified in roman numerals I-XII by their specific location of the brain and by the order in which they exit the cranium.
The cranial nerves originate in the brain and have power over some of the most important neurological functions of the body. Cranial nerves relay information between the brain and parts of the body, primarily to and from regions of the head and neck.
There are many cranial nerve mnemonics that can be memorable and rude/lewd. Either way, they can be helpful for remembering the names of the twelve cranial nerves, as well as remembering which nerves are sensory, motor, or both. Remembering cran...

The brain and the spinal cord have a protective layer called the dura mater. The dura mater is attached to the inside of the skull. Between the brain and the dura mater is the cerebral spinal fluid. The cerebral spinal fluid is the critical nutrient bath that nourishes the neurons of the central nervous system.. Important to the discussion of migraine headache is the realization that the dura mater itself contains blood vessels:. It is proposed that migraine headaches occur when the blood vessels of the dura mater dilate, depolarizing branches of the trigeminal nerve (cranial nerve V), sending the headache pain electrical signal to the trigeminocervical nucleus, then to the thalamus, then to the cortical brain where the pain is perceived (5, 7).. There is a synaptic communication between the trigeminal nerve (cranial nerve V) and the facial nerve (cranial nerve VII). The dilation of the dural blood vessels is via the facial nerve (cranial nerve VII), from the parasympathetic production and ...

In a prospective study of 271 new patients with nasopharyngeal carcinoma, 36 (13.3%) were found to have cranial nerve involvement. Serous otitis media (SOM) was found in 98 (41.4%) of 237 patients who had undergone complete otologic assessment. The local control of tumor and actuarial survival of three subgroups of patients, namely, 80 patients with SOM only, 11 patients with cranial nerve palsy only, and 18 patients with both SOM and cranial nerve palsy, were analyzed. The local control of tumor was better in patients with SOM alone than in those with cranial nerve palsy alone; those patients with both SOM and cranial nerve involvement had worse local control as well as survival. As SOM is not uncommon in the diagnosis of nasopharyngeal carcinoma, and adult-onset SOM is otherwise distinctly uncommon, this provides a good opportunity for early recognition and, perhaps, better control of nasopharyngeal carcinoma ...
Background: The cranial sensory ganglia represent populations of neurons with distinct functions, or sensory modalities. The production of individual ganglia from distinct neurogenic placodes with different developmental pathways provides a powerful model to investigate the acquisition of specific sensory modalities. To date there is a limited range of gene markers available to examine the molecular pathways underlying this process.. Results: Transcriptional profiles were generated for populations of differentiated neurons purified from distinct cranial sensory ganglia using microdissection in embryonic chicken followed by FAC-sorting and RNAseq. Whole transcriptome analysis confirmed the division into somato- versus viscerosensory neurons, with additional evidence for subdivision of the somatic class into general and special somatosensory neurons. Cross-comparison of distinct ganglia transcriptomes identified a total of 134 markers, 113 of which are novel, which can be used to distinguish ...
Alternating hemiplegia is a form of hemiplegia that has an ipsilateral and contralateral presentation in different parts of the body. The disorder is characterized by recurrent episodes of paralysis on one side of the body. There are multiple forms of alternating hemiplegia, Webers syndrome, middle alternating hemiplegia, and inferior alternating hemiplegia. This type of syndrome can result from a unilateral lesion in the brainstem affecting both upper motor neurons and lower motor neurons. The muscles that would receive signals from these damaged upper motor neurons result in spastic paralysis. With a lesion in the brainstem, this affects the majority of limb and trunk muscles on the contralateral side due to the upper motor neurons decussation after the brainstem. The cranial nerves and cranial nerve nuclei are also located in the brainstem making them susceptible to damage from a brainstem lesion. Cranial nerves III (Oculomotor), VI (Abducens), and XII (Hypoglossal) are most often associated ...
We observed that most CN palsies had 1 or more MRI findings of intracranial or orbital CN involvement; this may be a reason for the adverse prognostic significance of CN palsies, and patients with CN palsies are determined to be at stage T4.3. Several investigators have reported that the perineural tumor spread in patients with non-nasopharyngeal carcinoma of the head and neck is associated with an increased incidence of recurrence.18-21 However, in our series, MRI-detected CN involvement was not associated with the 3-year LRFS rate in NPC patients with local advanced disease. The primary treatment modality for NPC was radiation therapy, whereas that of other carcinomas of the head and neck was surgery. Lawrence and Cottel reported that postoperative radiotherapy of squamous cell carcinoma with perineural invasion resulted in a much improved survival probability when compared with that observed after conventional surgical excision.20 Radiation therapy (relatively large treatment volume) provided ...
The primary gustatory sensory nuclei in catfish are grossly divisible into a vagal lobe and a facial lobe. In this study, the reflex connections of each gustatory lobe were determined with horseradish peroxidase (HRP) tracing methods. In addition, in order to determine the loci and morphology of the other brainstem cranial nerve nuclei, HRP was applied to the trigeminal, facial, glossopharyngeal, or vagus nerve. The sensory fibers of the facial nerve terminate in the facial lobe. The facial lobe projects bilaterally to the posterior thalamic nucleus, superior secondary gustatory nucleus, and medial reticular formation of the rostral medulla ...

Key challenges for formal accounts of brain function are emotion, self-awareness and their disorders. Recently, people have started to cast emotional processing in terms of predictive coding or inference about interoceptive or bodily states [9,10,53,54]. The basic argument follows the explanation for action above, namely, motor reflexes are driven by proprioceptive prediction errors. Proprioceptive prediction errors compare primary afferents from stretch receptors with proprioceptive predictions that descend to alpha motor neurons in the spinal cord and cranial nerve nuclei. This effectively replaces descending motor commands with proprioceptive predictions, which are fulfilled by peripheral reflexes [24]. These predictions rest on deep hierarchical inference about states of the world, including our own body. Replacing proprioceptive signals with interoceptive signals, one can see how autonomic reflexes can transcribe descending interoceptive predictions into physiological homoeostasis (e.g. ...

These authors contributed equally to this work DOI : 10.5137/1019-5149.JTN.7876-13.3 Cranial neuropathy is usually idiopathic and familial cases are uncommon. We describe a family with 5 members with cranial neuropathy over 3 generations. All affected patients were women, indicating an X-linked dominant or an autosomal dominant mode of inheritance. Our cases and a review of the literature suggest that familial idiopathic cranial neuropathy is a rare condition which may be related to autosomal dominant vascular disorders (e.g. vascular tortuosity, sclerosis, elongation or extension), small posterior cranial fossas, anatomical variations of the posterior circulation, hypersensitivity of cranial nerves and other abnormalities. Moreover, microvascular decompression is the treatment of choice because vascular compression is the main factor in the pathogenesis. To the best of our knowledge, this is the first report of familial cranial neuropathy in China. Keywords : Cranial nerves, Familial, ...
Fig 3. Thin-section (2.5-mm) axial T1-weighted spoiled gradient-echo gadolinium-enhanced images of the brain obtained at 1.5 T for Gamma knife localization (trigeminal neuralgia). Cranial nerve enlargement (arrows) is most pronounced involving the mastoid or descending segments of cranial nerve VII (A), cisternal segments of cranial nerve III (B), V3 (C), and V2 (D) segments. Faint enhancement is identified. ...

The vertebrate body is characterized by its dual segmental organization: pharyngeal arches in the head and somites in the trunk. Muscular and nervous system morphologies are also organized following these metameric patterns, with distinct differences between head and trunk; branchiomeric nerves innervating pharyngeal arches are superficial to spinal nerves innervating somite derivatives. Hypobranchial muscles originate from rostral somites and occupy the
This is a print of a painting I created of the second cranial nerve, the optic nerve, which transmits visual information to the retina and brain. The optic nerve pathway is rendered in watercolor using a soft cool blue color palette. This piece of art is sure to stand out, impressing both medical and non-medical person
Because of our large brains our babies need to be born relatively immature. To enable passage through their mothers pelvis the upper bones of the skull develop seperately and can move over each other (moulding) during the birth process to navigate through the pelvis.. As baby travels through the pelvis it moves under its mothers pubic arch, and at this point there is potential for the nerves to be compressed or overstretched. This is more likely in instrumental births like forceps, ventouse and caesareans where traction is applied to the head to pull the baby out. There is also a possibility of this if the baby is pulled out by the head during a so called normal birth. (Note from Joy: in the normal birth process there should be no pulling on the babys head!).. If these nerves are dammaged the baby can suffer feeding problems, pain from the injury, impaired hearing and facial expressions. Cranial nerve injury can also affect arousal of the vagus nerve with increased heartrate, inability to ...
There are 12 cranial nerve excluding the R or N nerve. They are numbered from anterior ro posterior and are as below: I | Olfactory nerve Sensory input of scent II | Optic Sensory input from retina/fovea III | Oculomotor Motor output for control of eye and eyelid IV | Trochlear Motor control of eye V | Trigeminal Branches into 3 sub-nerves as below V1 Opthamic Scalp, forehead upper eyelid and nose V2 Maxillary Hard and sot palate, nasal cavity, cheek and temporal region of head V3 Mandibular Mus
