- Prolonged exercise
- Antidiuretic Hormone
- Diabetes Mellitus
- a 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.
- b Posterior Pituitary. Also called vasopressin, promotes water retention by kidneys. Secretion rate changes in response to alterations in blood osmolality and blood volume. Lack of ADH secretion is a cause of diabetes insipidus
- c 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.
- d Both GH and cortisol secretion increase. Blood glucose levels maintained!
- e Pancreas. Secreted by Beta cells. Target tissues: liver, adipose tissue, muscle, and satiety center of hypothalamus. Increases uptake of glucose and amino acids by cells. (in order to decrease blood glucose levels!)

- called the Adenohypophysis, consists of three areas with indistinct boundaries (pars distalis, pars intermedia, and pars tuberalis)
- Metabolism and tissue maturation, Ion regulation, Water balance, Immune system regulation, Heart rate and blood pressure regulation, Control of blood glucose and other nutrients, Control of reproductive functions and secondary sex characteristics, Uterine contractions and milk release
- Exocrine and endocrine. Endocrine part consists of pancreatic islets each of which is composed of alpha, beta, and delta cells. Secretes Glucagon, Insulin, and Somatostatin.
- Cause Dwarfism, Giantism in juveniles, and Acromegaly in adults
5 True/False Questions
Pheochromocytoma and neuroblastoma → Disorders of the adrenal medulla that are tumors. Result of exvessive production of epinephrine and roepinephrine. Symptoms are high blood pressure, sweating, nervousness, pallor, and tachycardia (rapid heart rate).
Mineralocorticoids → Zona fasciculata, Cortisol is major hormone that increases fat and protein breakdown, increases glucose synthesis, anti-inflammatory response (cortosone shot!)
Effects of aging on endrocrine system → Gradual decrease in secretory activity of some glands- GH, Melatonin, Thyroid hormones, Kidneys secrete less renin. Familial tendency to develop Type II diabetes.
Thyroid gland → 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.
Adrenal Glands → Also called the suprarenal glands. Functions as part of sympathetic nervous system. Composed of medulla and cortex (3 layers- zona glomerulosa, fasciculata, and reticularis). Hormones- Medulla secretes epinephrine and norepinephrine. Cortex secretes mineralocorticoids, glucocorticoids, androgens
