Embryology of the facial nerve Weeks 0-4-3rd wk : facioacoustic (acousticofacial) primordium -4th wk : chorda tympani nerve exits rostrally and courses ventrally to the first pharyngeal pouch to enter

Thalamic nuclei: MNG = Midline nuclear group AN = Anterior nuclear group MD = Medial dorsal nucleus VNG = Ventral nuclear group VA = Ventral anterior nucleus VL = Ventral lateral nucleus. The ventral lateral nucleus (VL) is a nucleus of the thalamus

Plan of the facial and intermediate nerves and their communication with other nerves. (“Nucleus of Facial N.” labeled at upper left.)

Chapter 5: Facial sensations & movements. In this chapter, the functions of the trigeminal (CN V) and facial (CN VII) nerves will be discussed.

Noyaux centraux du nerf facial. Le noyau somato-moteur du nerf facial se situe dans la protubérance du tronc cérébral.On comptabilise aussi les noyaux salivaire supérieur et lacrymo-nasal qui génèrent des fibres accompagnant le nerf facial sous le nom de nerf intermédiaire de Wrisberg (VII bis).

Gross anatomy Nuclei and brainstem tracts. Three brainstem nuclei contribute to the facial nerve: one motor, one secretomotor, and one sensory:. facial nerve nucleus in the pons; as the motor fibres of the facial nerve loop posteriorly over the abducens nerve nucleus, they form the facial colliculus in the floor of fourth ventricle

abducens nerve (cranial nerve VI) motor nerve innervating the lateral rectus muscle, which abducts the eye; lesions of the nucleus, which is located in the dorsal pons, produce a horizontal gaze palsy; nerve fibers exit the ventromedial pons and because of their long course are vulnerable to damage by mass lesions/increased intracranial pressure
