GENERAL HISTOLOGY

Detailed explanation-1: -Feedback control, both negative and positive, is a fundamental feature of biological systems. Some of these systems strive to achieve a state of equilibrium or “homeostasis". The major endocrine systems are regulated by negative feedback, a process believed to maintain hormonal levels within a relatively narrow range.

Detailed explanation-2: -What is a negative feedback mechanism? A negative feedback loop is one way that the endocrine system tries to keep homeostasis (stability) in the body. If an endocrine gland senses that there is too much of one hormone in the body, it will initiate changes to decrease production of that hormone.

Detailed explanation-3: -Feedback Control of Hormone Secretion The endocrine system is controlled by complex feedback mechanisms in which the secretion of a hormone is turned on (stimulated) or turned off (inhibited), depending on its concentration. Such feedback mechanisms help the body maintain homeostasis.

Detailed explanation-4: -The Endocrine system maintains homeostasis by producing hormones. These hormones are sent to different glands and organs which in turn make changes that help the body remain in balance. For example, the thyroid gland is an endocrine gland that helps to control metabolism.
