- Pheochromocytoma and neuroblastoma
- Adrenal Medulla Hormones
- Parathyroid glands
- Pineal Body
- a 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).
- b Regulates secretory activity of pituitary gland through neurohormones and action potentials. KNOW HORMONES
- c 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.
- d Epinephrine- (increases blood glucose levels, fat breakdown in adipose tissue releasing fatty acids into the blood) and norepinephrine. Both increase heart rate and force of contraction and cause blood vessels to constrict. Prepare individual for physical activity. Short half-life.
- e In epithalamus. Produces Melatonin- enhances sleep, immune response. and Arginine Vasotocin- regulates function of reproductive system in some animals
5 Multiple choice questions
- Anterior Pituitary. Play a role in analgesia in response to stress and exercise. Regulation of body temp, food intake, and water balance. Increase in response to stress and exercise.
- 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
- Males, from Gonads, Testosterone- regulates production of sperm cells and function of male reproductive organs and secondary sex characteristics. Inhibin- inhibits FSH secretion
- 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
5 True/False questions
Adrenal Cortex Hormones → Mineralocorticoids, Glucocorticoids, and Androgens
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
Effects of aging on endrocrine system → 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.
Luteinizing hormong (LH) and Follicle-stimulating hormone (FSH) → Anterior Pituitary. Increases skin pigmentation
Thyroid-Stimulating Hormone (THS) → Anterior Pituitary. Increases skin pigmentation
