Define Hypothalamic Control of Anterior Pituitary Gland
The hypothalamus controls many of the automatic functions of the body. It secretes a series of different neurosecretory substances called hypothalamic releasing and inhibitory factors. These factors are secreted into the blood vessels connecting hypothalamus and pituitary called the hypothalamic-hypophyseal portal system and then to the anterior pituitary gland, where they regulate secretion of the various anterior pituitary hormones.
