Document Summary
Cortisol which come from the outer region of the adrenal gland (the adrenal cortex) is involved in regulating aging. Higher level of cortisol in wild animals tend to accelerate the aging process. Pineal gland: produces melatonin, which in part is responsible for sleep: melatonin supplements can be purchased at the store to help people sleep. Contains the bodies thermostat, keeps body temperature at a constant level. It is also an endocrine structure that releases hormones into the pituitary gland, it does so in several manners: hypothalamic hormones can be released from the posterior pituitary, going to the blood. It also releases hormones in the anterior pituitary. Thyroid gland: produces thyroid hormones, which have effect on metabolism. Along with the parathyroid gland it produces hormones that are involved in calcium homeostatic. Feedback loop where calcitonin is released from the thyroid, parathyroid hormone is released from the parathyroid gland. They work to keep the blood-calcium level at a constant value.
