PNB 2264 Lecture Notes - Lecture 23: Gonadotropin-Releasing Hormone, Hypothalamus, Pituitary Gland
Document Summary
Must be understood by a protein (only a protein can do this) Machinery is biochemical (things can happen at a fast clip) Pac + ffa = dag and phosphoinositol: lets in calcium and this activates pkc which has targets inside the cell. Growth hormone: regulates growth, protein, works with rtkase. Tsh: regulated by trh, thyroid stimulating hormone, stimulates thyroid to produce thyroxin which contains iodine. Crh: produces acth, adrenocorticotropic hormone, makes steroids. You need this in order to give live birth, drives uterus to contract and push baby out. Saves water when our body needs it (working in high heat and not peeing much means your body is saving that water) Information controlled: age, diet, sex etc controls this. Releases ghrh in response to this info and the ghrh goes and releases growth hormone: athletes take gh to help build muscles. Increases mass of skeletal muscle: secretion of insulin-like-growth-factor (igf) in liver which also allows you to grow.
