Which mechanism of action is NOT common to both cortisol and growth hormone?   A. Muscle building   B. Mobilizing fatty acids

2. State which hormone is probably responsible for each physiological phenomenon described below and explain why. a) Blood glucose levels remained constant even though someone went 20 hours without eating or drinking. b) Heart rate and breathing rate increase when someone is awoken by a loud noise in the middle of the night. c) A grown man's jaw and forehead become thick and deformed.

The sympathetic postganglionic neurons release only norepinephrine while the adrenal medulla secretes mainly epinephrine (80%) and a small amount of norepinephrine (20%). The sympathetic postganglionic neurons do not secrete epinephrine because; Group of answer choices a. Epinephrine is not as widely used in the nervous system as norepinephrine b. Phenylethanolamine-N-methyltransferase (PNMT) which converts norepinephrine to epinephrine is present in the adrenal medulla, but not in sympathetic postganglionic adrenergic neurons c. Acetylcholine which stimulates the secretion of epinephrine does not act on postganglionic neurons d. Dopamine beta hydroxylase in hyperactive in the adrenal medulla

17. Steroid hormones are... a. polar hormones exert their effects via a second messenger system b. polar hormones exert their effects via an intracellular receptor C. nonpolar hormones exert their effects via an extracellular membrane receptor dnonpolar hormones exert their effects via a cytoplasmic or nuclear receptor e. nonexistent in the body

2. There are several functions of the thyroid hormone: list 3 major effects of thyroid hormone (T3/T4):

1. Explain and give an example of a positive feedback loop for the regulation of hormone secretion.   2.Explain the difference between prostaglandins and hormones. List some of the body functions that can be influenced by prostaglandins

3.On clinical examination of54-year-old woman the tumor of adrenal cortex was revealed. The glucoselevel in blood was increased. What is the main cause of hyperglycemia in this case? For answer:a)indicatethe hormone, which is elevated in the blood of patient;b)discuss this hormone synthesis and themechanism of signal transduction in target tissues; c)describe the metabolic pathways can be stimulated by this hormone in liver.

1.  When the carnival came to a small town, the local health professionals and consumer groups joined forces to enforce truth-in-advertising laws to protect selected employees of the carnival. They demanded that the fat man, the dwarf, the giant, and the bearded lady be billed as “people with endocrine system problems” (which of course removed all the sensationalism usually associated with these attractions). Identify the endocrine disorder in each case and explain how (or why) the disorder produced the characteristic features of these four-show people.

Overexpression of this receptor in the cells of the adrenal gland causes Cushing's syndrome, a disease caused by the overproduction of cortisol. One strategy that scientists have employed to treat this disease is the use of small molecules that bind to, but do not activate, MC2R. This type of molecule is generically referred to as an antagonist. How can an antagonist bind to the same receptor as ACTH but not activate it? O a. The antagonist can bind covalently while ACTH binds non-covalently O b. The antagonist is only partially complimentary to the binding pocket of MC2R O The antagonist binds to ACTH and blocks it from binding to the receptor properly O d. The antagonist is the exact same structure as ACTH but since it is synthetic it doesn't work One cause of Cushing's syndrome is the inappropriate production of GPCRS in the adrenal gland that are not normally present in those cells. When these receptors are activated they result in the production of cortisol. Which statement about…

Overdose by thyroid hormones in elderly patients most commonly leads to:A. Increased irritabilityB. Atrial fibrilationC. AggressionD. PsychosisE. Psychomotor excitation
