Question

Quizplus · Accepted Answer

GH stimulates the breakdown of stored fats and the release of fatty acids into the blood. This effect is known as lipolysis and is one of the primary functions of GH. GH also stimulates the growth and division of bone and cartilage cells (chondrocytes) and skeletal muscle cells. The production of GH is regulated by the hypothalamus and the pituitary gland, not the thyroid. GH has no known inhibitory effect on stem cell division in epithelial tissues.
