Lesions affecting the cavernous sinus may affect isolated nerves or all the nerves traversing through it. The pituitary gland lies between the two paired cavernous sinuses. An abnormally growing pituitary adenoma, sitting on the bony sella turcica, will expand in the direction of least resistance and eventually invade the cavernous sinus. [4]
The cavernous nerve plexus (also called the Walther plexus [1]) is situated below and medial to that part of the internal carotid artery which is placed by the side of the sella turcica in the cavernous sinus, and is formed chiefly by the medial division of the internal carotid nerve.
It traverses the cavernous sinus, above the other orbital nerves receiving in its course one or two filaments from the cavernous plexus of the sympathetic nervous system, and a communicating branch from the ophthalmic division of the trigeminal nerve.

For many people, sinus pain is not necessarily the picture of migraine that they have in their mind's eye, she says, but migraine attacks do frequently cause sinus pressure and pain.
The cavernous nerves are post-ganglionic parasympathetic nerves that facilitate penile erection and clitoral erection. [1] They arise from cell bodies in the inferior hypogastric plexus where they receive the pre-ganglionic pelvic splanchnic nerves (S2-S4). In the penis, there are both lesser cavernous nerves and a greater cavernous nerve.

The ophthalmic nerve (CN V 1) is a sensory nerve of the head. It is one of three divisions of the trigeminal nerve (CN V) , a cranial nerve . It has three major branches which provide sensory innervation to the eye , and the skin of the upper face and anterior scalp , as well as other structures of the head.
