MICROANATOMY

Detailed explanation-1: -While many parts of the body make hormones, the major glands that make up the endocrine system are the: hypothalamus. pituitary. thyroid.

Detailed explanation-2: -It receives many signals from various regions of the brain and in return, releases both releasing and inhibiting hormones, which then act on the pituitary gland to direct the functions of the thyroid gland, adrenal glands, and reproductive organs and to influence growth, fluid balance, and milk production.

Detailed explanation-3: -Oxytocin and vasopressin are produced by the hypothalamus but stored and are released into the bloodstream through the posterior pituitary. That is the reason why it is not a true endocrine gland. Endocrine glands are the ductless glands that produce and release hormones in the blood directly.

Detailed explanation-4: -The hypothalamus and pituitary gland are neuroendocrine organs. The hypothalamus and the anterior pituitary are two out of the three endocrine glands that are important in cell signaling. They are both part of the HPA axis which is known to play a role in cell signaling in the nervous system.

Detailed explanation-5: -The endocrine system regulates the metabolic activities of the body like body growth, sexual development & other biological processes. The endocrine gland signalling is slow but its effects are prolonged. Some of the major endocrine glands are the Pituitary, Pineal, Thyroid, Thymus, Gonads, etc.
