pterygoid canal

This nerve travels through the pterygoid canal to the pterygopalatine ganglion.

In this case; the artery passes backward along the pterygoid canal with the corresponding nerve.

The nerve of the pterygoid canal and a meningeal branch from the ascending pharyngeal artery pierce the layer of fibrocartilage.

A slender filament (sphenoidal) ascends to the nerve of the Pterygoid canal, and a small branch connects with the chorda tympani.

Pharyngeal branch of artery of pterygoid canal - "ramus pharyngeus arteriae canalis pterygoidei"

It The artery is a small, inconstant branch which passes into the pterygoid canal and anastomoses with a branch of the maxillary artery.

The pterygoid canal runs through the medial pterygoid plate of the sphenoid bone to the back wall of the pterygopalatine fossa.

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

Together, greater petrosal and deep petrosal nerves form the nerve of the pterygoid canal (vidian nerve) and reach the pterygopalatine ganglion in the pterygopalatine fossa.

The artery of pterygoid canal, the nerve of pterygoid canal and some venous drainage also pass through the foramen lacerum.

The artery of the pterygoid canal (Vidian artery) is an artery in the pterygoid canal, in the head.

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.

Its medial half forms the anterior boundary of the foramen lacerum, and presents the posterior aperture of the pterygoid canal for the passage of the corresponding nerve and artery.

The pterygoid canal (also vidian canal) is a passage in the skull leading from just anterior to the foramen lacerum in the middle cranial fossa to the pterygopalatine fossa.

It proceeds towards the foramen lacerum, where it joins the deep petrosal nerve (sympathetic) to form the nerve of the pterygoid canal, which passes through the foramen lacerum.

It transmits the nerve of pterygoid canal, artery of the pterygoid canal and vein of the pterygoid canal.

It then enters the cartilaginous substance which fills the foramen lacerum, and joins with the greater superficial petrosal nerve to form the nerve of the pterygoid canal, also known as the Vidian nerve.

It passes forward through the pterygoid canal with its corresponding artery (artery of the pterygoid canal) and is joined by a small ascending sphenoidal branch from the otic ganglion.

The PSN fibers of the nerve of the pterygoid canal synapse at the pterygopalatine ganglion, which is closely associated with the maxillary division of the trigeminal nerve (CN V).

The pharyngeal veins begin in the pharyngeal plexus on the outer surface of the pharynx, and, after receiving some posterior meningeal veins and the vein of the pterygoid canal, end in the internal jugular.

The angular prominence between the posterior margin of the vaginal process and the medial border of the scaphoid fossa is named the pterygoid tubercle, and immediately above this is the posterior opening of the pterygoid canal.

The nerve of the pterygoid canal (Vidian nerve) is formed by the junction of the great petrosal nerve and the deep petrosal nerve within the pterygoid canal containing the cartilaginous substance which fills the foramen lacerum.

This nerve carries the parasympathetic secretomotor fibers through the pterygoid canal, where it joins the deep petrosal nerve (containing postganglionic sympathetic fibers from the superior cervical ganglion) to form the nerve of the pterygoid canal (vidian nerve).
