Explanation Primary as well as secondary capillary plexus contribute to the hypophyseal portal system of the body. Primary capillary plexus form the first set of capillaries of the hypophyseal portal system in the median eminence of the hypothalamus. The hypothalamic neuron secretes releasing hormones that later enter the primary capillary plexus. The corticotrophin-releasing hormone then enters the primary capillary plexus and further enters the secondary capillary plexuses of the anterior pituitary. In the hypophyseal portal system, the second set of capillaries in the anterior lobe form the secondary capillary plexus...

Chapter 17, Problem 19RQ

Summary Introduction

To review:

The differences between the functions of both sets of capillaries in the hypophyseal portal system.

Introduction:

The hypothalamus of the brain is responsible for controlling the secretion of the hormone by the anterior pituitary. The structure of the hypothalamus secretes releasing as well as inhibiting hormones that either stimulate or inhibit the secretion of hormones from the anterior pituitary. The hormones reach the anterior pituitary through the portal system.
