Which branch of facial nerve passes through parotid gland?

Which branch of facial nerve passes through parotid gland?

The postganglionic secretomotor fibers that emerge from the otic ganglion reach the parotid gland via the auriculotemporal nerve (a branch of the mandibular division of the trigeminal nerve [CN V3]). The sympathetic supply is derived from the adjacent sympathetic plexus of the carotid sheath.

What is the nerve supply of parotid gland?

The parotid gland receives both sensory and autonomic innervation. General sensory innervation to the parotid gland, its sheath, and the overlying skin is provided by the auriculotemporal nerve. The autonomic innervation controls the rate of saliva production and is supplied by the glossopharyngeal nerve.

What is nervus intermedius?

The nervus intermedius is the sensory and parasympathetic division of the facial nerve. It contains visceral afferent fibers coming from the taste buds of the anterior two-thirds of the tongue and mucous membranes of the pharynx, nose, and palate. Taste pathways of the facial nerve.

Which branch of the facial nerve would you expect to find parallel to the parotid duct?

Buccal branch
Buccal branch: runs parallel to and 1 cm below the arch of the zygoma traveling toward the corner of the mouth. Thin-walled parotid duct travels closely adjacent, usually just below this branch.

Where does the facial nerve pass through?

The nerves typically travels from the pons through the facial canal in the temporal bone and exits the skull at the stylomastoid foramen. It arises from the brainstem from an area posterior to the cranial nerve VI (abducens nerve) and anterior to cranial nerve VIII (vestibulocochlear nerve).

Does the facial nerve innervate the parotid gland?

The facial nerve then passes through the parotid gland, which it does not innervate, to form the parotid plexus, which splits into five branches (temporal, zygomatic, buccal, marginal mandibular, and cervical) innervating the muscles of facial expression.

What does the facial nerve supply?

The facial nerve provides motor innervation of facial muscles that are responsible for facial expression, parasympathetic innervation of the glands of the oral cavity and the lacrimal gland, and sensory innervation of the anterior two-thirds of the tongue.

What is Jacobson nerve?

Jacobson’s nerve is a tympanic branch of the glossopharyngeal nerve, arising from its inferior ganglion. It enters the middle ear cavity through the inferior tympanic canaliculus, runs in a canal on the cochlear promontory and provides the main sensory innervation to the mucosa of the mesotympanum and Eustachian tube.

What is the Vidian nerve?

Vidian nerve, also known as the nerve of the pterygoid canal or nerve of the Vidian canal, is so named because of the canal in which it travels: the Vidian canal. It is formed by the confluence of two nerves: deep petrosal nerve (from the sympathetic plexus on the internal carotid artery) carrying sympathetic fibres.

Where does the facial nerve emerge through?

The facial nerve (the labyrinthine segment) is the seventh cranial nerve, or simply CN VII. It 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.

Which branch of facial nerve Innervates Nasalis?

buccal branch
Innervation. Nasalis muscle is innervated by the buccal branch of facial nerve (CN VII).

What are the branches of facial nerve?

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. Each of these branches provides input to a group of muscles of facial expression.
