- Pheochromocytoma and neuroblastoma
- Abnormalities in the secretion of growth hormone
- a 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!)
- b Cause Dwarfism, Giantism in juveniles, and Acromegaly in adults
- c Regulates secretory activity of pituitary gland through neurohormones and action potentials. KNOW HORMONES
- d 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).
- e Males, from Gonads, Testosterone- regulates production of sperm cells and function of male reproductive organs and secondary sex characteristics. Inhibin- inhibits FSH secretion
5 Multiple choice questions
- One of largest endocrine glands. Composed to two lobes connected by isthmus. Highly vascular. Composed of follicles. Parafollicular cells secrete calcitonin which reduces calcium concentration in body fluids when levels elevated
- Pancreas. Secreted by Alpha cells. Target tissue is liver. Causes breakdown of glycogen and fats for glucose energy. Increases glucose synthesis in liver. (to increase blood glucose levels!)
- Anterior Pituitary. Cause fat breakdown and release of fatty acids into circulatory system
- 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.
- 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.
5 True/False questions
Luteinizing hormong (LH) and Follicle-stimulating hormone (FSH) → Anterior Pituitary. Increases skin pigmentation
Posterior pituitary → Anterior Pituitary. stimulates milk production in lactating females
Antidiuretic Hormone → 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
Short-term and prolonged Exercise → Sympathetic stimulation increases epinephrine and glucagone secretion and inhibits insulin secretion. Muscle, liver, and adipose tissue help maintain blood glucose levels.
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.
