There are two types of hormones secreted in the endocrine system: Steroidal and non-steroidal, (or protein based) hormones. The endocrine system regulates its hormones through negative feedback, except in very specific cases like childbirth.
Endocrine glands are special groups of cells that make hormones. The major endocrine glands are: Vital to our overall health, hormone levels change as we grow and age.

The endocrine system is a chemical control system. It functions in conjunction with the nervous system to control the internal environment (homeostasis). Nervous System vs. Endocrine System – both systems enable cells to communicate with other by using chemical messengers.
The endocrine system comprises glands and tissues that secrete hormones to regulate and coordinate vital functions in the body. Endocrine glands differ from exocrine glands by releasing their secretions directly into the bloodstream, rather than a central duct.
Secretion of hormones is regulated by: 1. Ca2+-dependent exocytosisexocytosis (pituitary hormones, insulin, adrenaline) Ca2+ Synthesis - storage in vesicles - vesicle fusion with the membrane – hormone release. 2. By cleavage of the storage molecules (thyroid hormones – from thyroglobulin). 3. Adrenal steroids: little stor age but massive ...
