Hormones are chemical messengers produced by glands in the endocrine system. Endocrine tissues are specialised to produce such hormones, which have genes switched on according the the hormones they were designed to produce. The protein synthesis pages in the cell biology tutorial go into depth about protein production, which is relevant here as hormones consist of proteins.
The pituitary gland situated at the back of the brain is responsible for the creation of many hormones that are related to growth in animals. The amount of each hormone produce is regulated by the hypothalamus, a part of the brain situated next to the pituitary gland.
As stated, the hypothalamus is responsible for regulating the release of hormones from the pituitary gland. It is responsible for secreting releaser factors which instruct the pituitary gland to secret certain hormones. This is illustrated below.
Essentially, the Jacob-Monod hypothesis explained in the genetic control page of this tutorial is the model that is involved in the production of hormones
Essentially hormones are used on demand by the body to instruct cells in particular tissues to devote their resources to the production of a particular protein
The next page investigates the use of these hormones in animals with successive pages studying plant hormones.
