- Thyroid hormones
- Effects of aging on endrocrine system
- Parathyroid glands
- a Zona fasciculata, Cortisol is major hormone that increases fat and protein breakdown, increases glucose synthesis, anti-inflammatory response (cortosone shot!)
- b Gradual decrease in secretory activity of some glands- GH, Melatonin, Thyroid hormones, Kidneys secrete less renin. Familial tendency to develop Type II diabetes.
- c Produced by many tissues of the body, is an autocrine and paracrine regulatory substance. Promotes inflammation, pain, vasodilation of blood vessels, and is inhibited by aspirin.
- d Include Triiodothryronine or T3 and Tetraiodothyronine or T4 or thyroxine. Transported in blood. Bind with intracellular receptor molecules and initiate new protein synthesis. Increase rate of glucose, fat, protein metabolism in many tissues thus increasing body temperature. Normal growth of many tissues dependent on thyroid hormones. Calcitonin from parafollicular cells reduces blood calcium levels
- e Embedded in thyroid. Made up of chief cells, which secrete PTH increasing blood calcium levels, stimulates osteoclasts, and promotes calcium reabsorption by kidneys, and Oxyphils whose function is unknown.

- Also called hypophyis, secretes 9 major hormones
- an extension of the nervous system and is called the neurohypophysis, continuous with the brain, secretes neurohormones
- Mineralocorticoids, Glucocorticoids, and Androgens

5 True/False questions
Diabetes Mellitus → Results from inadequate secretion of insulin or inability of tissues to respond to insulin. Type I or IDDM (insulin dependent) develops in young people resulting from diminished insulin secretion. Type II or NIDDM (non-insulin dependent) develops in people older than 40-45 and is more common (obesity), results from the inability of tissues to respond to insulin.
Beta endorphins → Zona reticularis, Androstenedione and testosterone. Cause the development of male secondary sexual characteristics
Oxytocin → Posterior Pitutitary. Associated with pregnancy and birth. Promotes uterine contractions during delivery. Causes milk ejection in lactating women by stimulating smooth muscle-like cells associated with the alveoli of mammary glands. Also associated with the contraction of the smooth muscle of the uterus during menses and sexual intercourse. Stretch of the uterus, mechanical stimulation of the cervix, and stimulation of the breast nipples as in nursing stimulates oxytocin secretion. Not much is known about the effects of oxytocin in males
Within 1-2 hours after meal → Disorder characterized by hypersecretion of cortisol and androgens and possibly by excess aldosterone production. Causes increased blood glucose levels, muscle wasting, and accumulation of adipose tissue in the face and trunk of the body.
Anterior pituitary → an extension of the nervous system and is called the neurohypophysis, continuous with the brain, secretes neurohormones
