The hypothalamus, pituitary gland, and pineal gland makes up our brain. Two hormones are produced bythe hypothalamus and then stored in the posterior pituitary gland which are the anti-diuretic hormone (also called vasopressin), which controls water balance and blood pressure andoxytocin, which stimulates uterine contractions during labour and milk secretion during breastfeeding. The anterior pituitary gland produces the following hormones and releases them into the bloodstream: adrenocorticotropic hormone, which stimulates the adrenal glands to secrete steroid hormones, principally cortisol. growth hormone, which regulates growth, metabolism and body composition. pituitary gland produces essential hormones for everyday living. The pineal gland is a tiny endocrine gland found in the brain. It produces and secretes the hormone melatonin, which is a hormone that helps regulate biological rhythms such as sleep and wake cycles.
