greater petrosal nerve

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

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

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

Greater petrosal nerve (also known as the greater superficial 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.

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

The deep petrosal nerve joins with the greater petrosal nerve to form the nerve of the pterygoid canal, which enters the ganglion.

The greater petrosal nerve, which carries sensory fibers as well as preganglionic parasympathetic fibers, emerges from the anterior aspect of the ganglion.

It's largely innervated by the greater petrosal nerve (a branch of the facial nerve); and its axons project to the lacrimal glands and nasal mucosa.

The lesser petrosal nerve re-enters and travels through the temporal bone to emerge in the middle cranial fossa just lateral to the greater petrosal nerve.

Greater petrosal nerve - provides parasympathetic innervation to several glands, including the nasal gland, palatine gland, lacrimal gland, and pharyngeal gland.

The greater petrosal nerve travels through the middle ear and eventually combines with the deep petrosal nerve (sympathetic fibers) to form the nerve of the pterygoid canal.

The mucous membranes receive their postganglionic parasympathetic nerve innervation for mucous secretion originating from the greater petrosal nerve (a branch of the facial nerve).

Some of these preganglionic parasympathetic fibers persist within the greater petrosal nerve as they exit the geniculate ganglion and subsequently synapse with neurons in the pterygopalatine ganglion.

Hiatus for greater petrosal nerve or hiatus of the facial canal (hiatus canalis nervi petrosi majoris or hiatus canalis facialis)

They travel as a periarteriolar plexus with the middle meningeal artery, before they merge and form the deep petrosal nerve, which joins the greater petrosal nerve in the pterygoid canal.

The postganglionic parasympathetic fibers of the greater petrosal nerve, upon synapsing in the pterygopalatine ganglion, will distribute to the nose, palate, and lacrimal gland through various nerves leaving the pterygopalatine fossa.

The petrosal branch of middle meningeal artery enters the hiatus for greater petrosal nerve, supplies the facial nerve and anastomoses with the stylomastoid branch of the posterior auricular artery.

This proximity of the greater petrosal nerve to branches of the trigeminal nerve explains the phenomenon of lesions to the trigeminal nerve causing impaired lacrimation although the trigeminal nerve does not supply the lacrimal gland.

The sensory information from the mucous membranes of the nasopharynx and palate is carried along the greater petrosal nerve, while the chorda tympani nerve (and lingual nerve) carries taste input from the anterior two-thirds of the tongue, floor of mouth, and palate.

The geniculate ganglion contains special sensory neuronal cell bodies for taste, from fibers coming up from the tongue through the chorda tympani and from fibers coming up from the roof of the palate through the greater petrosal nerve (MJ Fitzgerald et al.

A shallow groove, sometimes double, leading lateralward and backward to an oblique opening, the hiatus for greater petrosal nerve (or hiatus of the facial canal), for the passage of the greater superficial petrosal nerve and the petrosal branch of the middle meningeal artery.
