petrosal nerve

The greater superficial petrosal nerve lies also underneath the ganglion.

The first is the greater petrosal nerve and the second is the chorda tympani.

Some of the fibres from the internal carotid plexus converge to form the deep petrosal nerve.

The visceral motor fibers pass through this plexus and merge to become the lesser petrosal nerve.

The chorda tympani is less responsive to sucrose than the greater superficial petrosal nerve.

The greater (superficial) petrosal nerve carries gustatory (taste) and parasympathetic fibres.

Ferrein's foramen: Hiatus of facial canal that makes passage for the greater petrosal nerve.

The deep and great petrosal nerves join together to form the vidian nerve, which passes over the foramen lacerum.

Hiatus for petrosal nerve can refer to:

Just distal to the geniculate ganglion, the facial nerve gives off the greater petrosal nerve.

Sympathetic postganglionic fibers from the deep petrosal nerve which do not synapse in pterygopalatine ganglion.

Petrosal nerve may refer to:

The greater superficial petrosal nerve is generally easy to visualize and can be followed retrograde to the geniculate ganglion.

The lesser petrosal nerve provides autonomic parasympathetic fibers that eventually innervate the parotid gland.

Petrosal nerve (disambiguation)

Preganglionic parasympathetic fibers originate from the glossopharyngeal nerve via the lesser petrosal nerve.

The greater petrosal nerve travels alongside branches of the V1 and V2 divisions of the trigeminal nerve.

Its parasympathetic root is derived from the nervus intermedius (a part of the facial nerve) through the greater petrosal nerve.

These fibers, from the superior cervical ganglion, travel through the carotid plexus, and then through the deep petrosal nerve.

The greater petrosal nerve, derived from the facial nerve, supplies the parasympathetic autonomic component of the lacrimal gland.

Dural elevation should proceed from posterior to anterior to avoid injury to an exposed greater superficial petrosal nerve or geniculate ganglion.

The lesser petrosal nerve then travels anteriorly from the hiatus toward the foramen ovale, through which it exits the cranial cavity.

Hiatus for lesser petrosal nerve (hiatus canalis nervi petrosi minoris)

Parasympathetic secretory fibers continue as the Lesser Petrosal nerve and provide secretomotor innervation to the parotid gland.
