Answer:
The three main components of the endocrine system are:
The hypothalamus; is involved in the release of CRH hormone into the blood to stimulate the release of cortisol from the adrenal gland; - Receives information from sensory organs and interprets it to send commands to other parts of the body; - Controls appetite and sleep cycles by releasing hormones that influence the release of hormones in other parts of the body.
The pituitary gland - secretes hormones that control the release of other endocrine hormones from the thyroid, adrenal, and gonads.
The thyroid gland - Synthesizes hormones that help regulate metabolism, cell growth, development, and behavior.
