What nerve Innervates the otic ganglion?

Glossopharyngeal Nerve (Cranial Nerve IX) These axons follow the tympanic and lesser petrosal nerves and innervate the otic ganglion, located just medial to the mandibular branch of the trigeminal nerve.

Is the auriculotemporal nerve part of the trigeminal nerve?

The auriculotemporal nerve is a tributary of the mandibular division of cranial nerve five, the trigeminal nerve. It contains sensory, vasomotor, and parasympathetic fibers.

What goes through the otic ganglion?

The otic ganglion is one of the four parasympathetic ganglia of the head. A collection of sensory neurons of the mandibular nerve, it works with the glossopharyngeal nerve and mandibular nerves to provide function to multiple salivary glands. It also has a motor function in chewing.

Which of the following nerves that innervate the face passes through the ciliary ganglion?

Ciliary Ganglion It is situated anteriorly to the superior orbital fissure, between the lateral rectus muscle and the optic nerve. Pre-ganglionic fibres: The ciliary ganglion is supplied by fibres from the Edinger-Westphal nucleus (associated with the oculomotor nerve).

Where does deep petrosal nerve come from?

The deep petrosal nerve is a branch from the internal carotid plexus. The plexus is located on the lateral side of the internal carotid as it courses superiorly. The deep petrosal enters the skull through the carotid canal with the internal carotid artery.

What is the greater petrosal nerve?

The greater petrosal nerve or superficial petrosal nerve is a branch of the nervus intermedius (nerve of Wrisberg) that carries parasympathetic, taste, and sensory fibers of the facial cranial nerve (CN VII).

Does auriculotemporal nerve pass through parotid gland?

2.5. The auriculotemporal nerve is intimately associated with the parotid gland and it then courses superiorly posterior to the TMJ. It crosses the zygoma and lies behind the superficial temporal artery. The terminal branches of the auriculotemporal nerve go on to innervate the scalp.

Which is the source of the Zygomaticotemporal nerve?

The zygomaticotemporal nerve (zygomaticotemporal branch, temporal branch) is a small nerve of the face. It is derived from the zygomatic nerve, a branch of the maxillary nerve (CN V2). It is distributed to the skin of the side of the forehead.

What suspends the otic ganglion?

Each ganglion is suspended from a branch of the trigeminal (V) nerve. Each has three roots: sensory, sympathetic and parasympathetic; the otic ganglion, in addition, has a fourth motor root.

What is the function of the ganglion?

Ganglia are ovoid structures containing cell bodies of neurons and glial cells supported by connective tissue. Ganglia function like relay stations – one nerve enters and an other exits.

What does the short ciliary nerve innervate?

Parasympathetic fibers from the ciliary ganglion (via the oculomotor nerve), sympathetic fibers from the adjacent ICA and somatosensory fibers form about 8-10 short ciliary nerves which enter the posterior globe to autonomically innervate the ciliary body and sphincter pupillae and supply sensation to the sclera.

How is deep petrosal nerve formed?

Excerpt. The deep petrosal nerve is a branch from the internal carotid plexus. The plexus is located on the lateral side of the internal carotid as it courses superiorly. The deep petrosal enters the skull through the carotid canal with the internal carotid artery.

Where does the auriculotemporal nerve synapse in the otic ganglion?

This nerve synapses in the otic ganglion and its postganglionic fibers form the inferior, parasympathetic root of the auriculotemporal nerve. The two roots re-unite and shortly after the “united” auriculotemporal branch gives off parotid branches, which serve as secretomotor fibers for the parotid gland.

How is the otic ganglion connected to the tongue?

It’s connected to the chorda tympani nerve and the nerve of the pterygoid canal, which is an alternate taste pathway from the front portion of the tongue. Any nerve structure can be damaged by diseases or infections that affect nerves or by traumatic injury, such as that from surgery or an accident.

Where does the parotid branch of the auriculotemporal nerve travel?

The inferior branch of the auriculotemporal nerve gives its secretory-motor fibers to the parotid branch. The parotid branch travels first to the otic ganglion (which is a collection of nerve cells in your ear) and there forms a synapse, which is a connection that allows for communication between nerves.

Where do parasympathetic fibres reach the otic ganglion?

Pre-ganglionic fibres: The ganglion is supplied by fibres from inferior salivatory nucleus (associated with the glossopharyngeal nerve). Parasympathetic fibres travel within a branch of the glossopharyngeal nerve, the lesser petrosal nerve, to reach the otic ganglion.
