The Endocrine System

Function of System:

The Endocrine System is made up of glands that produce and secrete hormones, chemical substances produced in the body that regulate the activity of cells or organs.

How it aids in homeostasis:

These hormones regulate the body's growth, metabolism, and sexual development and function.

Name and function of Major Organs:

The major glands of the endocrine system are the hypothalamus, pituitary, thyroid, parathyroids, adrenals, pineal body, and the reproductive organs (ovaries and testes). The pancreas is also a part of this system; it has a role in hormone production as well as in digestion.

Comparative anatomy:



The insect endocrine system produces neurohormones as well as hormones that control molting, diapause, reproduction, osmoregulation, metabolism, and muscle contraction.

Among the crustaceans, the major neuroendocrine system consists of the neurosecretory X-organ and its associated neurohemal organ, the sinus gland.Three neurosecretory centres have been identified in the simple nemertine brain; one centre controls the maturation of the gonads, and all three appear to be involved in osmotic regulation.

Three neurosecretory centres in Phylum Nemertea have been identified in the simple nemertine brain; one centre controls the maturation of the gonads, and all three appear to be involved in osmotic regulation.
