To discuss:
Six hormones secreted by the hypothalamus; how they regulate the anterior pituitary, and their effects.
Introduction:
The hypothalamus and the pituitary gland are primarily involved in the hormone cascade pathway and they stimulate signals to their target glands. The hypothalamus is located in the brain, below the thalamus. It links the nervous and endocrine system through the pituitary gland. The secretion of all the hormones from the pituitary gland is controlled by the hypothalamus. When the hypothalamus receives signals from nerves, it produces neuroendocrine signals to other endocrine glands. It maintains homeostasis and regulates body temperature, hunger, sleep, and reproduction. It also regulates certain
