Hypophysiotropic endocrines (endocrines released from hypothalamus to apg through portal vasculature of the infundibulum: stimulatory (5): 2 lobes straddling trachea just below larynx, composed of follicles: edged with follicular cells (boundary) connected by tight junctions. Have receptors for tsh, which triggers production of e3 in interstitial fluid called colloid. Shrinks when we get older because plays big part in brain development when we are young. Can have neurodevelopment deficits if gland isn"t functioning pro]\perly. Changes how we run our metabolism and energy usage: Increases glucose utilization and breakdown of fat, protein, then bone to get energy. Makes vascular smooth muscle more responsive to epinephrine and norepinephrine (sympathetic. Negative feedback on (can inhibit) growth and reproduction. Keeps you with enough energy available so you will live until tomorrow. Bind to same nuclear receptors found in most cells. Tsh from apg and inhibit trh release from hypothalamus. Receptors in nucleus of most cells in your body.
