innervates the lip muscles including the obicularis oris and the zygomaticus. The muscles must contract during the oral preparatory and oral transport stages of the swallow to prevent food from dribbling out of the mouth. The facial also innervates the buccinator muscles of the cheeks. These must remain tense during the oral component of the swallowing process to prevent the pocketing of food between the teeth and the cheeks. Sensory Component carries information about taste from the anterior 2/3 of the tongue.
Nerve that supplies sensory and parasympathetic fibers to the tongue, palate, and the narrow passage from the mouth, and motor fibers to the muscles of the face and jaw.
The seventh cranial nerve, responsible for control of the muscles of the face. Damage to branches of this nerve during facial piercings can result in paralysis of facial muscles.
cranial nerve that supplies facial muscles
Nerve controlling muscles of facial expression
the seventh cranial nerve, controlling motion of the face, the tear glands and taste on the tip of the tongue, as well as several other functions; the facial nerve travels together with the vestibulocochlear nerve in the internal auditory canal and may be compressed or damaged by an acoustic neuroma or an operation.
A cranial nerve that controls most of the muscles in the face. This is a separate nerve from the trigeminal nerve, which controls sensation in the face and some of the muscles that control chewing.
Cranial Nerve VII, which has motor and sensory components; motor component governs muscles of facial expression; some taste fibers and salivary gland nerve fibers course within the facial nerve.
The facial nerve is the seventh (VII) of twelve paired cranial nerves. It emerges from the brainstem between the pons and the medulla, and controls the muscles of facial expression, and taste to the anterior two-thirds of the tongue. It also supplies preganglionic parasympathetic fibers to several head and neck ganglia.
