- Thyroid hormones
- Antidiuretic Hormone
- Adrenal Cortex Hormones
- a 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
- 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 Mineralocorticoids, Glucocorticoids, and Androgens
- d Decreased metabolic rate, Weight gain, reduced appetite, Dry and cold skin, Weak, flabby skeletal muscles, sluggish, Myxedema, Apathetic, somnolent, Coarse hair, rough dry skin, Decreased iodide uptake, Possible goiter, Cretinism
- e Anterior Pituitary. stimulates milk production in lactating females
5 Multiple choice questions
- Sympathetic stimulation increases epinephrine and glucagone secretion and inhibits insulin secretion. Muscle, liver, and adipose tissue help maintain blood glucose levels.
- 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.
- Both GH and cortisol secretion increase. Blood glucose levels maintained!
- Female, from Gonads, Estrogen and Progesterone- uterine and mammary gland development and function, genitalia structure, sex characteristics, menstrual cycle. Inhibin- inhibits FSH secretion. Relaxin- increases flexibility of symphysis pubis and dilation of the cervix
- Gradual decrease in secretory activity of some glands- GH, Melatonin, Thyroid hormones, Kidneys secrete less renin. Familial tendency to develop Type II diabetes.
5 True/False questions
Abnormalities in the secretion of growth hormone → Cause Dwarfism, Giantism in juveniles, and Acromegaly in adults
Oxytocin → Reseased from the thymus, plays an important role in development and maturation of the immune system
Parathyroid glands → 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.
Prostaglandins → 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.
Lipotropins → Anterior Pituitary. Cause fat breakdown and release of fatty acids into circulatory system
