The two endocrine glands located in the brain are the pituitary gland and the pineal gland. The pituitary gland is often referred to as the "master gland" because it controls the functions of many other endocrine glands in the body, while the pineal gland helps regulate sleep-wake cycles through the secretion of melatonin.
The Pineal Gland and the Pituitary Gland are located in the hypothalamus in the brain.
The pituitary gland and the pineal gland are the two endocrine glands located in the brain. The pituitary gland produces and secretes hormones that control many functions of other glands in the body, while the pineal gland produces the hormone melatonin, which helps regulate sleep-wake cycles.
The pituitary gland is larger than the pineal gland. The pituitary gland is about the size of a pea and is located at the base of the brain, while the pineal gland is about the size of a grain of rice and is located in the center of the brain.
The two categories of glands based on their method of secretion are exocrine glands, which secrete their products into ducts that lead to the external environment or another surface, and endocrine glands, which secrete hormones directly into the bloodstream.
Two components of the endocrine system are hormones (chemical messengers that regulate various bodily functions) and glands (organs that secrete hormones into the bloodstream).
Starting at the top, the parathyroids (two on each side of the thyroid, one on its surface, the other either on the surface or buried inside), the adrenals and the testes or ovaries.
