Where are hormones made?
Glands of the endocrine system are widely scattered throughout the body.
The pituitary gland is known as the master gland. It is divided into an anterior and posterior part.
The pituitary secretes somatotrophs, corticotrophs, thyrotrophs, lactrotrophs and gonadotrophs.
The adrenal glands (cortex) produce mineralocorticoids.
One of these is aldosterone which regulates sodium levels. It also produces glucocorticoids one of which is cortisone.
It is also regulates carbohydrates and these also help regulating blood pressure.
Another of these works with epinephrine and is an important the stress response.
The adrenal medulla produces epinephrine and norepinephrine.
There are endocrine structures in the pancreas. One secretes fluids that drain into the small intestine.
These fluids contain glucagon, insulin, somatostatin and pancreatic peptides.
The testes also produce hormones: testosterone. The ovaries produce estrogens and progesterone.
If there is a placenta present that also produces hormones human chorionic gonadotropin, estrogens and progesterone.
The thymus produces a hormone called thymosin which stimulates development of T cells.
The G.I. tract also produces hormones: gastrin, secretin and cholecystokinin.
These regulates the motor activities in the digestive system. One more is ghrelin which boosts appetite.
The heart as an endocrine role as well atrial natriuretic hormone. This hormone lowers blood pressure.
The parathyroid glands produce calcitonin which regulates vitamin D balance and calcium.
There are many other glands and tissues that produce hormones: inhibin, leptin and resistin.
