The facial muscles are innervated by facial nerve (cranial nerve VII). In contrast, the nearby masticatory muscles are innervated by the mandibular nerve, a branch of thetrigeminal nerve (V).
Cranial nerve 7 is also referred to as the facial nerve. It has both sensory and motor components. Its sensory portion is responsible for taste on the anterior two thirds of the tongue as well as sensation for a small patch of skin by the ear. Its motor component is responsible for innervating the muscles of facial expression.
You have three nerves, which supply your forearm. Radial, ulnar and median nerve. Out of these three nerves, median nerve is the main nerve to supply forearm muscles and some of the hand muscles.
He has Bell's Palsy - a paralysis of the facial nerve resulting in inability to control facial muscles on the affected side.
Bell's Palsy - a form of paralysis affecting a nerve that controls facial muscles.
Facial nerve
Facial nerve, the seventh cranial nerve. It leaves the brain along with eighths cranial nerve through internal acoustic meatus and comes out through stylomastoid foramen to supply the muscles of facial expression.
They are facial muscles innervated by the facial nerve that, among other things, control facial expression.
All muscles of facial expression are supplied by seventh cranial nerve. That is Facial nerve. This nerve carries the taste sensation from anterior two third of the tongue also.
Facial Nerve (VII)
The facial nerve, also known as the seventh cranial nerve (CN VII), is an important nerve in the human body responsible for controlling various facial muscles. The facial nerve is essential for facial expression, the sense of taste, and certain functions related to hearing and balance. Here is a detailed overview of the facial nerve, its functions, anatomy, and related conditions: Functions of the facial nerve: Engine function: The main function of the facial nerve is to control facial expression muscles. It stimulates the muscles that allow us to smile, frown, close our eyes, move our lips, and make many other facial movements. Taste sensation: The facial nerve carries taste information from the anterior two-thirds of the tongue, including the taste buds for sweet, salty, sour, and bitter tastes. Salivary glands: The facial nerve also innervates the submandibular and sublingual salivary glands, which are responsible for the production and digestion of saliva. Tear glands and nasal glands: It controls the lacrimal (tear) and nasal glands, contributing to tearing and the production of nasal secretions.
Facial nerve
The sural nerve is cutaneous and therefore does not supply any muscles.
It should supply with glossopharyngeal & facial nerve.
The Facial Nerve or Cranial Nerve VII is the nerve involved with Bell's Palsy.
Cranial nerve 7 is also referred to as the facial nerve. It has both sensory and motor components. Its sensory portion is responsible for taste on the anterior two thirds of the tongue as well as sensation for a small patch of skin by the ear. Its motor component is responsible for innervating the muscles of facial expression.
you lose intervation (nerve supply) to the muscles. so yes. you lose intervation (nerve supply) to the muscles. so yes.
It makes no sense because the facial muscles are innervated by the facial nerve. And this nerve comes off the brain stem.
