Module 1: Anatomy and Physiology of Growth Hormone

Glossary

Anabolic: having the ability to build, particularly muscle; the constructive part of
metabolism concerned especially with macromolecular synthesis.

Endocrine: function that influences several physiological systems and can be
described as a collection of glands that produce hormones that regulate metabolism,
growth and development, tissue function, sleep and a variety of other things.

Glycogenolysis: breakdown of glycogen to form glucose molecules.
Homeostasis: the maintenance of relatively stable internal physiological conditions
(as body temperature or the pH of blood) in higher animals under fluctuating
environmental conditions.
Hyperphagia: abnormally increased appetite for food frequently associated with
injury to the hypothalamus.
IGF-1: abbreviation for insulin-like growth factor 1, the juvenile form of insulin-like
growth factor that is produced chiefly by the liver in response to growth hormone with
production declining after puberty.
Lipolysis: breakdown of fat to free-fatty acids.

Paracrine: signaling or communication from cell to cell. In paracrine function, a cell
produces a signal to induce changes in nearby cells. Since paracrine signals act
locally between cells that are close together, these types of signals usually elicit
quick responses that last only a short amount of time.

Peptide: any of various amides that are derived from two or more amino acids by
combination of the amino group of one acid with the carboxyl group of another and
are usually obtained by partial hydrolysis of proteins.
