It accompanies the lienal artery to the spleen, giving off, in its course, subsidiary plexuses along the various branches of the artery. The spleen is a ductless, vertebrate gland that is closely associated with the circulatory system, where it functions in the destruction of old red blood cells in holding a reservoir of blood. ...

The cavernous plexus 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. ... The superior cervical ganglion, the largest of the cervical ganglia, is placed opposite the second and third cervical vertebræ.
