Difference between Sphenoid bone and Trochlear nerve

Sphenoid bone vs. Trochlear nerve

The sphenoid bone is an unpaired bone of the neurocranium. It is situated in the middle of the skull towards the front, in front of the temporal bone and the basilar part of the occipital bone. The sphenoid bone is one of the seven bones that articulate to form the orbit. Its shape somewhat resembles that of a butterfly or bat with its wings extended. The trochlear nerve, also called the fourth cranial nerve or cranial nerve IV, is a motor nerve (a somatic efferent nerve) that innervates only a single muscle: the superior oblique muscle of the eye, which operates through the pulley-like trochlea.

Similarities between Sphenoid bone and Trochlear nerve

Sphenoid bone and Trochlear nerve have 5 things in common (in Unionpedia): Cavernous sinus, Homology (biology), Internal carotid artery, Posterior clinoid processes, Superior orbital fissure.

Cavernous sinus

The cavernous sinus within the human head, is a true dural venous sinus (not a venous plexus) creating a cavity called the lateral sellar compartment bordered by the temporal bone of the skull and the sphenoid bone, lateral to the sella turcica.

Homology (biology)

In biology, homology is the existence of shared ancestry between a pair of structures, or genes, in different taxa.

Internal carotid artery

The internal carotid artery is a major paired artery, one on each side of the head and neck, in human anatomy.

Posterior clinoid processes

In the sphenoid bone, the anterior boundary of the sella turcica is completed by two small eminences, one on either side, called the anterior clinoid processes, while the posterior boundary is formed by a square-shaped plate of bone, the dorsum sellæ, ending at its superior angles in two tubercles, the posterior clinoid processes, the size and form of which vary considerably in different individuals. The posterior clinoid processes deepen the sella turcica, and give attachment to the tentorium cerebelli.

Superior orbital fissure

The superior orbital fissure is a foramen in the skull, although strictly it is more of a cleft, lying between the lesser and greater wings of the sphenoid bone.
