The Hypoglossal Nerve (CN XII) Damage to the hypoglossal nerve is a relatively uncommon cranial nerve palsy. Possible causes include tumours and penetrating traumatic injuries. If the symptoms are accompanied by acute pain, a possible cause may be dissection of the internal carotid artery.ig 1.0 – The extracranial anatomical course of the hypoglossal nerve. The hypoglossal nerve arises from the hypoglossal nucleus in the medulla oblongata of the brain. It then passes laterally across the posterior cranial fossa, within the subarachnoid space. The nerve exits the cranium via the hypoglossal canal.

Hypoglossal nerve The path of the nerve starts in the hypoglossal nucleus of the brainstem, which is located near the midline of the medulla oblongata, and then travels between the carotid artery and jugular vein to end up on the underside of the tongue. If there are problems with the hypoglossal nerve, the tongue may become paralyzed.

- 1 CN I, the olfactory nerve, carries information regarding smell from the nose to the brain. 2  Loss of the sense of smell may indicate damage to CN I, such as from a tumor, known as an olfactory groove meningioma, according to Mayfield. 3  CN II, the optic nerve, carries visual information to the brain for processing.

Optic nerve 1 Damage to the optic nerve anterior to the optic chiasm causes loss of vision in the eye on the same side as the damage. 2  Damage at the optic chiasm typically causes loss of vision laterally in both visual fields (bitemporal hemianopsia).

Optic nerve In general: 1  Damage to the optic nerve anterior to the optic chiasm causes loss of vision in the eye on the same side as the damage. 2  Damage at the optic chiasm typically causes loss of vision laterally in both visual fields (bitemporal hemianopsia). It may occur with large pituitary tumors pituitary adenoma.

Drop Foot (Foot Drop) and Steppage Gait (Footdrop Gait) Drop Foot/Foot Drop: A Symptom. Drop foot is not a disease but a symptom of an underlying problem. Depending on the cause, drop foot may be temporary or permanent. Often drop foot is caused by injury to the peroneal nerve deep within the lumbar and sacral spine. The peroneal nerve is a division of the sciatic nerve.

Foot drop Foot drop can sometimes be caused by nerve damage linked to diabetes (known as a neuropathy). Inherited conditions such as Charcot-Marie-Tooth disease are also a common cause of peripheral nerve damage and muscle weakness that can lead to foot drop.

Hypoglossal nerve The path of the nerve starts in the hypoglossal nucleus of the brainstem, which is located near the midline of the medulla oblongata, and then travels between the carotid artery and jugular vein to end up on the underside of the tongue. If there are problems with the hypoglossal nerve, the tongue may become paralyzed. To test the nerve’s function, a patient would be asked to stick out their tongue. If paralysis were present, the tongue would point in the direction of the affected side. Another test monitors the strength of the tongue by having the patient press their tongue against the side of their cheek.

Diabetic Neuropathy (Nerve Damage) Diabetic neuropathy is a peripheral nerve disorder caused by diabetes or poor blood sugar control.The most common types of diabetic neuropathy result in problems with sensation in the feet. It can develop slowly after many years of diabetes or may occur early in the disease.The symptoms are numbness, pain, or tingling in the feet or lower legs.iabetic neuropathy is a peripheral nerve disorder caused by diabetes or poor blood sugar control.

The 12 Cranial Nerves Cranial Nerve XII: The Hypoglossal Nerve Stemming from between the gracile and cuneate fasciculus, this nerve exits the skull via the hypoglossal canal. It motorically innervates the muscles of the tongue, except the palatoglossus, which is innervated by the vagus nerve (CN X).

Facial Palsy If the nerve is damaged during surgical intervention to remove a Vestibular Schwannoma, the Facial Nerve, CN7, it might be possible to reattach the nerve to the Hypoglossal Nerve, CN12. This type of nerve graft can be done to try to regain blood flow to the nerve immediately after the nerve loses connectivity.

Tibial nerve The sural nerve also branches off the tibial nerve and provides sensation in the skin of the legs and feet. Damage to the tibial nerve results in a condition known as tibial nerve dysfunction. This is characterized by a loss of feeling or movement in the lower leg.

- Any nerve in the body can be affected by diabetes. Another cause of vagus nerve damage is trauma to the vagus nerve. This can be caused by trauma to the body, such as a car accident, that puts pressure on part of the vagus nerve. Surgery also can put pressure on the vagus nerve and cause damage.

- Causes of peroneal nerve injury (foot drop). Foot drop injury can be caused by an injury to the spinal cord or from other underlying diseases, such as amyotrophic lateral sclerosis (ALS) , multiple sclerosis (MS) , or Parkinson's disease.

Clinical Connections Chapter 14 Injury to the glossopharyngeal (IX) nerve causes dysphangia, or difficulty swallowing; aptylia, or reduced secretion of saliva; loss of sensationin the throat; and ageusia, or loss of taste sensation. The glossopharyngeal nerve may be injured as a result of conditions such as trauma or lesions.

Optic nerve Damage to the optic nerve typically causes permanent and potentially severe loss of vision, as well as an abnormal pupillary reflex, which is diagnostically important. The type of visual field loss will depend on which portions of the optic nerve were damaged.

- Symptoms. Symptoms depend on which nerves are damaged and how they were damaged. Cranial nerve disorders can affect smell, taste, vision, sensation in the face, facial expression, hearing, balance, speech, swallowing, and muscles of the neck.

Loss of smell (anosmia) Damage to your brain or nerves. Your olfactory system, which provides your sense of smell, consists of receptors in the mucous lining of your nose that send information through nerves into your brain. You can lose your sense of smell if any part of the olfactory pathway is damaged or destroyed. This can happen as a result of: Aging.

- If one of the 2nd cranial nerves (optic nerve) is damaged, the affected eye is blind. If any of the three cranial nerves that control eye movement (3rd, 4th, or 6th cranial nerve) is damaged, people cannot move their eyes normally. Symptoms include double vision when looking in certain directions. If the 3rd cranial nerve (oculomotor nerve) is paralyzed, the upper eyelid is paralyzed.

Cranial Nerves Damage to the hypoglossal nerve will weaken the side of the tongue that is parallel to the affected portion of the nerve, causing reduced movement of the tongue. For example, if the left branch of the cranial nerve is damaged, the left side of the tongue will be affected.ypoglossal Nerve-Cranial Nerve XII. The hypoglossal nerve is the twelfth cranial nerve, which means that it is located the closest to the back of the head. Its primary purpose is to control the movement of the tongue.

Understanding Saphenous Nerve Entrapment It is important to realize that many cases of saphenous nerve entrapment are actually caused by a problem at the hip or foot. If the muscles around these segments are not working properly it will affect the alignment and biomechanics of the knee.

- Editor, PodiatryNetwork.com. Tarsal Tunnel Syndrome is due to compression of a nerve called the Posterior Tibial Nerve.The nerve passes into the foot from around the inside of the ankle just below the ankle bone. Just beyond this point, the nerve enters the foot by passing between a muscle and a bone in the foot. This area is called the Tarsal Tunnel. The Posterior Tibial Nerve is the largest nerve that enters the foot. At the level of the ankle, the nerve branches out like the branches of a tree as it goes out toward the toes.
