- Antidiuretic Hormone
- Melanocyte-Stimulating Hormone (MSH)
- a 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
- b Anterior Pituitary. Increases skin pigmentation
- c Zona reticularis, Androstenedione and testosterone. Cause the development of male secondary sexual characteristics
- d Reseased from the thymus, plays an important role in development and maturation of the immune system
- e Secreted by Delta cells. Inhibits both beta and alpha cells
5 Multiple choice questions
- Anterior Pituitary. stimulates milk production in lactating females
- 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
- 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
- Parathyroid gland. Also called Parathormone. Targets bones, kidneys, and intestine. Increases blood calcium levels by stimulating osteoclast activity, increases phosphate release from bone but also increases excretion in the kidney to decrease blood phosphate levels.
- 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).
5 True/False questions
Glucocorticoids → 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.
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.
Hormonal regulation soon after a meal → Decreasing blood glucose levels. Sympathetic stimulation causes decreased insulin secretion, increase glucagon secretion, increase in GH, cortisol, and epinephrine secretion.
Oxytocin → Reseased from the thymus, plays an important role in development and maturation of the immune system
