| Question | Answer |
|---|---|
| What are the three stages of the stress response or GAS (General adaptation syndrome) in order of occurrence? | Fight or Flight, Resistance, Exhaustion |
| Increases blood calcium levels | Parathormone |
| Increases blood glucose level | Glucagon |
| Decreases blood calcium levels | Calcitonin |
| Decreases blood glucose level | Insulin |
| Initiates and maintains milk secretion by the mammary glands | Prolactin |
| Regulates the body's biological clock | Melatonin |
| Stimulates sex hormone production; triggers ovulation | Luteinizing hormone |
| Augments fight or flight responses | Epinephrine and norepinephrine |
| Regulates metabolism and resistance to stress | Cortisol |
| Helps control water and electrolyte homeostasis | Aldosterone |
| Suppresses release of FSH | Inhibin |
| Stimulates growth of axillary and pubic hair | Androgens |
| Promotes T cell maturation | Thymosin |
| Regulates oxygen use, basal metabolic rate, cellular metabolism, and growth and development | Thyroxine and triodothyronine |
| Stimulates protein synthesis, inhibits protein breakdown, stimulates lipolysis and retards use of glucose for ATP production | Human growth hormone |
| Inhibits water loss through the kidneys | Antidiuretic hormone |
| Stimulates egg and sperm formation | Follicle-stimulating hormone |
| Enhances uterine contrations during labor;stimulates milk ejection | Oxytocin |
| Increases skin pigmentation when present in excess | Melanocyte-stimulating hormone |
| Stimulates the synthesis and release of T3 and T4 | Thyroid-stimulating hormone |
| Local hormones involved in inflammation, smooth muscle contraction, blood flow, and infammation | prostaglandins |
| Corticotrophs release which hormone? | ACTH and MSH |
| Thyrotrophs release which hormone? | TSH |
| Alpha cells of the pancreatic islet release | Glucagon |
| Chief cells release | PTH |
| Zona fasciculata cells release | Glucocorticoids |
| Gonadotrophs release | FSH and LH |
| Parafollicular cells of the thyroid gland release | Calcitonin |
| Beta cells of the pancreatic islet release | Insulin |
| Zona reticularis cells release | Androgens |
| Ovaries release | Progesterone |
| Chromaffin cells release | Epinephrine and norepinephrine |
| Somatotrophs release | hGH |
| Testes relase | Testosterone |
| Zona glomerulosa cells release | mineralocorticoids |
| Follicular cells fo the thyroid gland release | Thyroxine and Triiodothyronine |
| Lactotrophs release | PRL |
| Hyposecretion of insulin or down-regulation of insulin receptors | Diabetes Mellitus |
| Hypersecretion of hGH before closure of epiphyseal plates | Giantism |
| Hyposecretion of thyroid hormone that is present at birth | Congenital hypothyroidism |
| Hypersecretion of glucocorticoids | Cushing's syndrome |
| Hyposecretion of hGH before closure of epiphyseal plates | Pituitary dwarfism |
| Hypersecretion of hGH after closure of epiphyseal plates | Acromegaly |
| Hypersecretion of epinephrine and norepinephrine | Pheochromocytomas |
| Hyposecretion of glucocorticoids and aldosterone | Addison's disease |
| Hypersecretion of melatonin | Seasonal Affective disorder |
| Hyposecretion of ADH | Diabetes insipidus |
| Hyposecretion of thyroid hormone in adults | Myxedema |
| Hyperthyroidism, an autoimmune disease | Grave's disease |
| Lipid-soluble steroid hormones and thyroid hormones affect cell funtion by | Altering gene expression |
| Water soluble hormones alter cell function by | Activating plasma memberane receptors, which elicit production of a second messenger that activates various enzymes inside the cell |
| Hormonal actions have what three types of effects? | Permissive, synergistic, or antagonistic |
| Exocrine Glands secrete | Products through ducts into body cavities or onto body surfaces |
| Endocrine glands secrete | Hormones into interstitial fluid, then hormones diffuse into the blood |
| abnormal enlargement of the thyroid gland | Goiter |
