Accessory nerve

The accessory nerve is a spinal nerve that supplies the sternocleidomastoid and trapezius muscles.

Auriculotemporal nerve

The auriculotemporal nerve is a branch of the mandibular nerve (V3) that runs with the superficial temporal artery and vein, and provides sensory innervation to various regions on the side of the head.

Carotid canal

The carotid canal is the passageway in the temporal bone through which the internal carotid artery enters the middle cranial fossa from the neck.

Deep petrosal nerve

The deep petrosal nerve (large deep petrosal nerve) is given off from the internal carotid plexus, and runs through the carotid canal lateral to the internal carotid artery.

Glossopharyngeal nerve

The glossopharyngeal nerve, known as the ninth cranial nerve (CN IX), is a mixed nerve that carries afferent sensory and efferent motor information.

Inferior ganglion of glossopharyngeal nerve

The inferior ganglion of the glossopharyngeal nerve (petrous ganglion) is larger than the superior ganglion and is situated in a depression in the lower border of the petrous portion of the temporal bone which is named fossula petrosa.

Inferior tympanic canaliculus

The inferior tympanic canaliculus is a small passage of the tympanic branch of the glossopharyngeal nerve and inferior tympanic artery.

Internal carotid plexus

The internal carotid plexus (internal carotid plexus) is situated on the lateral side of the internal carotid artery, and in the plexus there occasionally exists a small gangliform swelling, the carotid ganglion, on the under surface of the artery.

Jugular fossa

The jugular fossa is a deep depression in the inferior part of the base of the skull.

Lesser petrosal nerve

The lesser petrosal nerve (also known as the small superficial petrosal nerve) is the General visceral efferent (GVE) component of the glossopharyngeal nerve (CN IX), carrying parasympathetic pre-ganglionic fibers from the tympanic plexus to the parotid gland.

Otic ganglion

The otic ganglion is a small parasympathetic ganglion located immediately below the foramen ovale in the infratemporal fossa and on the medial surface of the mandibular nerve.

Paraganglioma

A paraganglioma is a rare neuroendocrine neoplasm that may develop at various body sites (including the head, neck, thorax and abdomen).

Parasympathetic nervous system

The parasympathetic nervous system (PSNS) is one of the two divisions of the autonomic nervous system (a division of the peripheral nervous system (PNS)), the other being the sympathetic nervous system.

Parotid gland

The parotid gland is a major salivary gland in many animals.

Postganglionic nerve fibers

In the autonomic nervous system, fibers from the ganglion to the effector organ are called postganglionic fibers.

Superior cervical ganglion

The superior cervical ganglion (SCG) is part of the autonomic nervous system (ANS) responsible for maintaining homeostasis of the body.

Sympathetic nervous system

The sympathetic nervous system (SNS) is one of the two main divisions of the autonomic nervous system, the other being the parasympathetic nervous system.

Temporal bone

The temporal bones are situated at the sides and base of the skull, and lateral to the temporal lobes of the cerebral cortex.

Trigeminal nerve

The trigeminal nerve (the fifth cranial nerve, or simply CN V) is a nerve responsible for sensation in the face and motor functions such as biting and chewing; it is the largest of the cranial nerves.

Tympanic cavity

The tympanic cavity is a small cavity surrounding the bones of the middle ear.

New!!: Tympanic nerve and Tympanic cavity · See more »

Tympanic plexus

In the tympanic cavity, the tympanic nerve (a branch of CN IX) divides into branches which, along with sympathetic fibres from the carotid plexus, form the tympanic plexus. This plexus is located on the surface of the promontory.

Vagus nerve

The vagus nerve, historically cited as the pneumogastric nerve, is the tenth cranial nerve or CN X, and interfaces with parasympathetic control of the heart, lungs, and digestive tract.
