ANATOMY

Detailed explanation-1: -The hypothalamus is the master switchboard. It’s the part of the brain that controls the endocrine system. That pea-sized structure hanging below it is the pituitary gland. It’s called the master gland because it regulates the activity of the glands.

Detailed explanation-2: -To maintain homeostasis, the hypothalamus works with the pituitary gland to control hormone production. This includes the thyroid and parathyroid glands, adrenal glands, pancreas, ovaries (in females), and testis (in males).

Detailed explanation-3: -The hypothalamus helps manage your body temperature, hunger and thirst, mood, sex drive, blood pressure and sleep.

Detailed explanation-4: -For each system, the hypothalamus secretes releasing hormones (i.e., CRH, GnRH, and TRH) that act on the pituitary gland. In response to those stimuli, the pituitary gland releases ACTH, gonadotropins (i.e., LH and FSH), or TSH. ACTH activates the adrenal glands to release cortisol, which induces metabolic effects.
