Facial nerve cervical

By David Terfera, Shereen Jegtvig. The muscles of mastication the ones that move your mouth and jaw when you eat are innervated by the mandibular nerve motor fibers of CN V. Sensory nerves originate from a number of places, for example, sensory nerves to the skin covering the neck and posterior scalp come from the cervical nerves. Marginal mandibular branch: Innervates the muscles of the lower lip and chin. Posterior auricular branch: Has branches that innervate the muscles around the ear and the occipitofrontal muscle. Temporal branch: Innervates the muscles that wrinkle the forehead, close the eyelids, and wiggle the ear.

Locating the cervical motor branch of the facial nerve: anatomy and clinical application.

The cervical branch of the facial nerve runs forward beneath the platysma , and forms a series of arches across the side of the neck over the suprahyoid region. One branch descends to join the cervical cutaneous nerve from the cervical plexus. Also supplies the platysma muscle. From Wikipedia, the free encyclopedia.

Motor and Sensory Facial Nerves

In this article, we shall look at the anatomical course of the nerve, and the motor, sensory and parasympathetic functions of its terminal branches. The course of the facial nerve is very complex. There are many branches, which transmit a combination of sensory, motor and parasympathetic fibres.

Definition The facial nerve seventh cranial nerve , CN VII , latin: nervus facialis is a mixed cranial nerve consisting of motor, sensory, and visceromotor fibers. The main functions of the facial nerve include controlling the muscles of facial expression, and providing taste sensations from the anterior part of the tongue. Functionally, the facial nerve consists of two parts: somatosensory and visceromotor part. The somatosensory part of the facial nerve provides the innervation for all of the facial expression muscles and the muscles of the neck, while the visceromotor part contributes to the parasympathetic innervation of the lacrimal gland, salivary glands, and mucous glands of the nasal cavity, also providing sensory fibers that transmit taste sensations from the tongue. The facial motor nucleus motor provides the facial nerve with general somatic efferent fibers, the superior salivatory nucleus parasympathetic gives rise to general visceral efferent fibers of the facial nerve , and the solitary tract nucleus or nucleus of the solitary tract nuclear complex sensory , which is responsible for taste sensation transmitted via special visceral afferent fibers of the facial nerve.
