Qu'est-ce (qui) est nucleus nervi hypoglossi - définition

ANATOMICAL ENTITY
Nucleus nervi hypoglossi; Hypoglossal motor nucleus; Nucleus of the hypoglossal; Nucleus of hypoglossal; Nucleus of hypoglossal nerve; Nucleus of the hypoglossal nerve

Hypoglossal nucleus         
The hypoglossal nucleus is a cranial nerve nucleus, found within the medulla. Being a motor nucleus, it is close to the midline.
Mesencephalic nucleus of trigeminal nerve         
Mesencephalic trigeminal nucleus; Mesencephalic nucleus; Nucleus mesencephalicus nervi trigemini; Mesencephalic trigeminal tract; Mesencephalic nucleus of the trigeminal nerve; Nucleus mesencephalicus
The mesencephalic nucleus of trigeminal nerve is involved with reflex proprioception of the periodontium and of the muscles of mastication in the jaw that functions to prevent biting down hard enough to lose a tooth. To subserve this reflex protective function, mechanoreceptive nerves in the periodontal ligament sense tooth movement and project to the mesencephalic nucleus.
Facial motor nucleus         
Nucleus of the facial nerve; Facial nerve nucleus; Facial nucleus; Motor facial nucleus; Nucleus nervi facialis; Motor nucleus of facial nerve; Facial motor nuclei; Motor nucleus of the facial nerve; Facial motor neurons
The facial motor nucleus is a collection of neurons in the brainstem that belong to the facial nerve (cranial nerve VII). These lower motor neurons innervate the muscles of facial expression and the stapedius.

Hypoglossal nucleus

The hypoglossal nucleus is a cranial nerve nucleus, found within the medulla. Being a motor nucleus, it is close to the midline. In the open medulla, it is visible as what is known as the hypoglossal trigone, a raised area (medial to the vagal trigone) protruding slightly into the fourth ventricle.

The hypoglossal nucleus is located between the dorsal motor nucleus of the vagus and the midline of the medulla. Axons from the hypoglossal nucleus pass anteriorly through the medulla forming the hypoglossal nerve which exits between the pyramid and olive in a groove called the anterolateral sulcus.
