The hypoglossal nerve, also known as the twelfth cranial nerve, cranial nerve XII, or simply CN XII, is a cranial nerve that innervates all the extrinsic and intrinsic muscles of the tongue except for the palatoglossus, which is innervated by the vagus nerve.

You may not think about your hypoglossal nerve much. But it’s an important part of your anatomy. It helps you move your tongue. It allows you to speak, swallow and push substances around in your mouth. Conditions affecting hypoglossal nerve function include stroke, cancer and ALS.

2024年11月2日 · The hypoglossal nerve arises from the hypoglossal nucleus in the medulla oblongata of the brainstem. It then passes laterally across the posterior cranial fossa, within the subarachnoid space. The nerve exits the cranium via the hypoglossal canal of the occipital bone.

2022年11月7日 · Examining the hypoglossal nerve involves observing the primary innervation target of the nerve, the tongue. The 3 observable aspects of the tongue are strength, bulk, and dexterity. Special attention is given when the tongue is weak, atrophied, moving abnormally, or …

2024年5月20日 · The hypoglossal nerve is purely motor nerve, which innervates extrinsic tongue muscles and geniohyoid muscle. It originates from it motor nucleus found in the ventral medulla oblongata. This article will discuss the anatomy and function of the hypoglossal nerve.

2024年10月14日 · What Is the Hypoglossal Nerve? The hypoglossal nerve is also known as the 12th cranial nerve. It is chiefly a motor nerve and carries motor fibers that control muscles. It does have some...

2024年10月21日 · The hypoglossal nerve is the 12th cranial nerve whose function is to enable the tongue to move. Damage to this nerve can affect speech, chewing, and swallowing. Medical conditions or injury can impair hypoglossal nerve function.

Correct differential diagnosis and suitable treatment require a thorough knowledge of the anatomical background of the region. This review presents the broad spectrum of hypoglossal neuropathies, paying particular attention to these with a compressive background.

2022年6月18日 · The hypoglossal nerve is the twelfth cranial nerve (CN XII) (TA: nervus hypoglossus or nervus cranialis XII).

The Hypoglossal nerve is the 12th cranial nerves that originate from the medulla obligate of the brain stem. It innervates all the extrinsic and intrinsic muscles of the tongue, except for the palatoglossus which is innervated by the vagus nerve. It is a nerve with a solely motor function.
