Figure 1-5. Coronal magnetic resonance imaging section through the amygdala, optic chiasma, intundihu-lum, and internal capsule. The cavernous sinus encircles the sella turcica and contains the following structures: cranial nerves (CN) III, IV, VI, V-l, and V-2; postganglionic sympathetic fibers; and the internal carotid artery. This is a T1-weighted image.

Essentials of Human Physiology

This ebook provides an introductory explanation of the workings of the human body, with an effort to draw connections between the body systems and explain their interdependencies. A framework for the book is homeostasis and how the body maintains balance within each system. This is intended as a first introduction to physiology for a college-level course.
