Chapter 13, Problem 7CR
Summary Introduction
To review:
The rationale behind sensitivity of the pineal gland to the light despite its location deep within the brain.
Introduction:
The pineal gland is a small, pea-shaped endocrine gland. It is located deep in the brain in the roof of 3rd ventricle. The secretion from this gland, melatonin, is necessary to maintain the circadian cycle. The sensitivity of this gland to the light is necessary for the maintenance of the circadian cycle.
