Hormone, growth
A hormone made in the pituitary gland that stimulates the release of another hormone called somatomedin by the liver, thereby causing growth. Growth hormone is synonymous with somatotropin and somatropin.
More specifically (and technically), growth hormone is produced by the anterior pituitary, the front section of the gland, and is a polypeptide consisting of 191 amino acids. It induces increased protein synthesis, increased mobilization of free fatty acids, and decreased glucose utilization.
Growth hormone is given to children with pituitary dwarfism (short stature due to underfunction of the anterior pituitary) to help them grow.

- Hormone, mineralocorticoid
A group of hormones, the most important being aldosterone, that regulates the balance of water and electrolytes (ions such as sodium and potassium) in the body. The mineralocorticoid hormones act specifically on the tubules of the kidney.
- Hormone, parathormone
Hormone made by the parathyroid gland (behind the thyroid gland in the neck). Parathormone (pronounced para-thor-mone) is critical to calcium and phosphorus balance. Deficiency of parathormone results in abnormally low calcium in the blood (hypocalcemia). Also call parathyrin.
- Hormone, progesterone
A female hormone, progesterone is the principal progestational hormone. Progestational hormones prepare the uterus (the womb) to receive and sustain the fertilized egg.
- Hormone, secretin
Hormone made by glands in the small intestine that stimulates pancreatic secretion. The word “hormone” was coined by the English physiologists Wm. M. Bayliss and Ernest H. Starling in connection with their discovery of secretin, the first hormone, in 1902.
