Cards in this set: Term GH(somatotropin) Definition Origin: Ant. Pit. Structure: Protein Regulated: Stim-GHRH Inhib-Somatostatin F(x): growth of bone and cartilage;increase protein synthesis in body;lipids to FA for energy;decrease use of glucose as energy source which raises glucose levels resulting in increased glycogen storage. Excess: Symmetric gigantism in children and acromegaly in adults Deficiency: In children causes symmetrical dwarfism. Term How does GH act on the liver? Definition Indirectly by inducing liver to produce somatomedins(protein growth factors). Term How does malnutrition effect GH?   Definition Increased levels of blood glucose or aminos, as it occurs in malnutrition, stimulates the pituitary to stimulate the secretion of GH, thereby restoring lost tissue proteins  Term Negative Feedback control of GH Definition Somatomedin production inhibit GH production by; 1)direct action on AP 2) secretion of somatostatin from hypothalamus 3)GHRH from hypo. inhibits its own secretion  Term PRL(prolactin) Definition ORIGIN: AP(acidophil cells) STRUCTURE: Protein REG: PRH(stim) and ESPECIALLY PIF(inhib)
