What do the branches of the facial nerve innervate?
Other muscles innervated by branches of the facial nerve are the anterior, superior, and posterior auricular muscles; and the occipitofrontalis muscle. The anterior, superior, and posterior auricular muscles all elevate the ear by pulling it upward.
Does the facial nerve innervate the parotid gland?
The facial nerve courses through the parotid gland, providing motor supply to the muscles of facial expression but does not provide innervation to the gland.
What are the 5 branches of facial nerve?
The facial nerve then enters the parotid gland, and branches into five divisions (see above). The facial nerve has five main branches, although the anatomy can vary somewhat between individuals. The branches are, from top to bottom: frontal (or temporal), zygomatic, buccal, marginal mandibular, and cervical.
Which muscle is supplied by facial nerve?
The facial nerve supplies motor and sensory innervation to the muscles formed by the second pharyngeal arch, including the muscles of facial expression, the posterior belly of the digastric, stylohyoid, and stapedius.
What Innervates submandibular gland?
Innervation. The submandibular glands receive autonomic innervation through parasympathetic and sympathetic fibres, which directly and indirectly regulate salivary secretions respectively.
What nerve innervates the submandibular gland?
The submandibular glands receive their parasympathetic input via the chorda tympani nerve, which is a branch of the facial nerve via the submandibular ganglion.
Where is the 7th facial nerve located?
brainstem
The facial nerve, also known as the seventh cranial nerve, cranial nerve VII, or simply CN VII, is a cranial nerve that emerges from the pons of the brainstem, controls the muscles of facial expression, and functions in the conveyance of taste sensations from the anterior two-thirds of the tongue.
Where is the 7th facial cranial nerve?
The two 7th Cranial Nerves (CN VII) are located on either side of the brainstem, at the top of the medulla. They are mixed cranial nerves with BOTH sensory and motor function. CN VII controls the face and is mainly FACE MOVEMENT with some face sensation.
What are the 5 facial nerves?
The facial nerve has five main branches, although the anatomy can vary somewhat between individuals. The branches are, from top to bottom: frontal (or temporal), zygomatic, buccal, marginal mandibular, and cervical.
What does the trigeminal nerve supply?
Gross Anatomy. The trigeminal nerve is the largest and most complex of the 12 cranial nerves (CNs). It supplies sensations to the face, mucous membranes, and other structures of the head. It is the motor nerve for the muscles of mastication and contains proprioceptive fibers.
What Innervates the sublingual gland?
The sublingual glands receive their parasympathetic input via the chorda tympani nerve, which is a branch of the facial nerve via the submandibular ganglion.
