Chapter 5: Facial sensations & movements The motor portion of. this nerve supplies the muscles of the face and scalp: buccinator, platysma and so on, along with. motor control to the submandibular, sublingual and lacrimal glands. The sensory portion of this. nerve carries sensory information for taste from the anterior 2/3 of the tongue and the palate. Lesions of the facial nerve cause facial paralysis that is usually unilateral. There is also a loss of. taste sensation in the anterior 2/3 of the tongue and decreased salivation.

nerve Home > Nervous System > Nerves of the Head and Neck > Tongue and Taste. The tongue is made up of muscles covered by mucous membranes. These muscles are attached to the lower jaw and to the hyoid bone, which is located just above the larynx and anchors the muscles of the tongue (it is the only bone in the body that doesn't touch any other bone).

Glossopharyngeal nerve The glossopharyngeal nerve connects to the brainstem at the upper medulla, travels through the base of the skull at the jugular foramen, and ends in the mouth in the mucous glands, palatine tonsil, and the base of the tongue.

Glossopharyngeal nerve The glossopharyngeal nerve is the ninth (IX) of the twelve pairs of cranial nerves. It exits the brainstem out from the sides of the upper medulla, just rostral to the vagus nerve and has sensory, motor, and autonomic components.upply. There are a number of functions of the glossopharyngeal nerve: 1  receives general sensory fibers from the tonsils, the pharynx, the middle ear and the posterior one third of the tongue. 2  receives special sensory fibers (taste) from the posterior one-third of the tongue.

Neurological Examination Cranial nerve X (vagus nerve). This nerve is mainly responsible for the ability to swallow, the gag reflex, some taste, and part of speech. The patient may be asked to swallow and a tongue blade may be used to elicit the gag response. Cranial nerve XI (accessory nerve). This nerve is involved in the movement of the shoulders and neck.

Chapter 51: The mouth tongue and teeth 51-2 A). The anterior two thirds of the tongue is supplied by (1) the lingual nerve (of the mandibular nerve) for general sensation and by (2) the chorda tympani (a branch of the facial nerve that runs in the lingual nerve) for taste.

- The salivation center is a pair of nuclei located just rostral to the dorsal nucleus of the vagus, the superior and inferior salivatory nuclei. They supply the parasympathetic innervation of the various salivary glands, and send their axons through the facial and glossopharyngeal nerves.his nucleus is also located near the midline. It is very small, and hard to find in sections. It looks like a crescent-notch taken out of a dark fiber bundle in the rostral pons. The fiber bundle is the MLF, which carries eye movement signals between brainstem nuclei.

The Urinary Bladder Neurological control is complex, with the bladder receiving input from both the autonomic (sympathetic and parasympathetic) and somatic arms of the nervous system: 1  The sympathetic nervous system communicates with the bladder via the hypogastric nerve (T12 – L2). It causes relaxation of the detrusor muscle.

Trigeminal Neuralgia (See also Overview of the Cranial Nerves.) Trigeminal neuralgia is severe facial pain due to malfunction of the 5th cranial nerve (trigeminal nerve). This nerve carries sensory information from the face to the brain and controls the muscles involved in chewing. The cause is usually an abnormally positioned artery that compresses the trigeminal nerve.

Glossopharyngeal neuralgia (throat pain) Figure 1. The glossopharyngeal nerve (9th cranial nerve) is related to the back of the tongue and throat. It has branches to the ear, tonsil, and carotid body. Glossopharyngeal pain can be similar to trigeminal neuralgia – and misdiagnosed.

Nervous System Anatomy Facial Nerve (VII) This nerve is both motor and sensory. It also has parasympathetic functions controlling the lacrimal gland, as well as the mandibular and sublingual salivary glands. It leaves the cranium by way of the internal auditory meatus and then exits from the skull via the stylomastoid foramen.

The Cranial Nerve Exam The vagus nerve (cranial nerve X) has autonomic functions in the thoracic and superior abdominal cavities. The special senses are served through the cranial nerves, as well as the general senses of the head and neck. The movement of the eyes, face, tongue, throat, and neck are all under the control of cranial nerves.

- The parasympathetic nerves that regulate digestion for the liver, stomach, pancreas, small intestine, and part of the large intestine are vagus nerves (the tenth cranial nerve). Unlike the splanchnic nerves, these nerves carry messages directly to the brain.he hormones that control digestion are produced and secreted by various organs along the tract. These hormones cause the various chemicals that aid in digestion to be released or prevented from being released.

SYSTEMIC CAUSES OF DYSPHAGIA IN ADULTS The act of swallowing is the most intricate neuromuscular action carried out in the body. It involves a myriad of cranial nerves, both sensory and motor, parasympathetic nerves, and both skeletal and smooth muscle. Special senses, such as smell and taste, and dental and salivatory functions also are involved.

Cranial Nerves of the Face and Mouth: Motion and Sensation Functionality This is mainly thanks in part to the fact that the facial nerve also conveys the sensation of taste from the anterior two-thirds of your tongue. And, even before you put the steak in your mouth, there is saliva inside of your mouth that will help in the process of digestion. Two out of the three of the most important salivary glands are innervated by the facial nerve. These glands are known as the submandibular and sublingual salivary glands. Combined, these two glands produce the vast majority of the saliva in your mouth.

River Landforms Meanders are bends in a river that form as a river’s sinuosity increases. The sinuosity of a river is a measurement of how much a river varies from a straight line. It’s a ratio between the channel length and displacement (straight line distance) between two points in the river’s course:

- The Hypoglossal nerve (CN XII) provides motor supply to the muscles of the tongue. Observe the tongue for any signs of wasting or fasciculations. Ask the patient to stick their tongue out. If the tongue deviates to either side, it suggests a weakening of the muscles on that side.

How your bladder works Bladder nerves. The nerves that control your bladder can be described as follows: Parasympathetic nerves from the S2, S3 and S4 levels of your spinal cord cause the upper part of your bladder to contract and your bladder neck to relax, assisting in the process of micturition (urination).

The Cranial Nerves and Their Functions The Facial Nerve The facial nerve is complicated. Not only does it control most muscles of the face; this nerve also transmits taste signals from the front of the tongue, conveys parasympathetic fibers that make the eyes tear and mouth salivate, and is responsible for a little bit of sensation around the ear.

The Facial Nerve (CN VII) Special Sensory Functions. The chorda tympani branch of the facial nerve is responsible for the taste innervation of the anterior 2/3 of the tongue. The nerve arises in the facial canal, and travels across the bones of the middle ear, exiting via the petrotympanic fissure, and entering the infratemporal fossa.
