Names such as Hormones and Endocrine are relatively new and both are derived from old Greek words endon(within), krinein (to separate) and hormao (to stimulate). Term Endocrine was first used to describe ductless glands by the French physiologist Gustave-Edouard Laguesse in 1893. Term Hormone was coined and first used by British physiologist Ernest Starling in 1905 to describe a new a factor (secretin) secreted from the intestines into the blood which was able to stimulate the pancreas.
The Endocrine System is the collection of glands that produce hormones which regulate metabolism, growth and development, tissue function, sexual function, reproduction, fertility, sleep, and mood, among many other things. The main function of Endocrine Glands is to secrete hormones directly into the blood stream. Protein or polypeptide hormones are made of chains of amino acids and steroid hormones are derived from lipids.
Hormones are chemical compounds that trek throughout the body coordinating complex processes, influencing the function of the immune system and even altering behaviour. Before birth, they guide development of the brain and reproductive system.They travel either in the blood stream or in the fluid around cells, looking for target cells. Once hormones find a target cell, they bind with specific protein receptors inside or on the surface of the cell and specifically change the cell’s activities. In essence, hormones serve as messengers, controlling and coordinating activities throughout the body.
