Document Summary
Hypothalamus: introduction, key regulation structure- directly or indirectly controls most hormone activity, region of brain- neuroendocrine tissue makes neurohormones links nervous and endocrine systems. Pituitary gland (2 lobes in humans: posterior pituitary, secretes adh, oxytocin made by hypothalamus, h2o conservation needed (stimulus) adh released targets kidneys collecting ducts more permeable to h2o. 2. terms for sets of hormones from hypothalamus, ap, target endocrine glands, and response in target tissue in general: hypothalamus ap other gland target tissue . Thyroid hormone: several effects response, stimulates cellular metabolism in virtually all cells, maintains normal blood pressure, heart rate, muscle tone. 3. regulate digestive, reproductive, functions: thyroid regulation. 2. thyroid gland: 2 lobes, ventral surface of trachea in neck, secretes 2 hormones (both called th, both derived from tyrosine and iodine (1) triiodothyronine = t3, 3 iodine (2) thyroxine = t4, 4 iodine. Hormonal regulation of growth: growth hormone (gh, peptide hormone secreted by ap, stimulates growth (tropic and nontropic)
