- Melanocyte-Stimulating Hormone (MSH)
- Thyroxine and triiodothyronine
- Thyroid gland
- a Made from the amino acid, tyrosine. Require iodine for their synthesis. Are transported in the blood by thyroxine-binding globulin, are involved in the regulation of metabolism
- b 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
- c Anterior Pituitary. Increases skin pigmentation
- d Males, from Gonads, Testosterone- regulates production of sperm cells and function of male reproductive organs and secondary sex characteristics. Inhibin- inhibits FSH secretion
- e Secreted by Delta cells. Inhibits both beta and alpha cells
5 Multiple choice questions
- 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
- Blood glucose levels, including amino acids and fatty acids, increase. Taken up into cells.. Parasympathetic stimulation and increasing blood glucose levels cause increased insulin secretion from pancreas. Nutrients move into cells.
- called the Adenohypophysis, consists of three areas with indistinct boundaries (pars distalis, pars intermedia, and pars tuberalis)
- 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.
- 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.
5 True/False questions
Oxytocin → Reseased from the thymus, plays an important role in development and maturation of the immune system
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).
Interleukin-2 → 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!)
Adrenal Medulla Hormones → Mineralocorticoids, Glucocorticoids, and Androgens
Thyroid hormones → 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
