Biology 172 Quiz 16A: Hormones and the Endocrine System

pineal hormone that synchronizes body rhythms

pituitary hormone that stimulates cell growth, especially muscle and bone growth

thyroid hormone that stimulates metabolism (BMR) and energy utilization

adrenal hormone that assists glucagon in the regulation of blood glucose by promoting the breakdown of fats and proteins

hormone that stimulates the relase of calcium from bone rresulting in an increase in blood calcium levels

pancreatic hormone that regulates blood glucose levels by promoting the breakdown of glycogen to glucose and the production of glucose from amino acids and fats

adrenal hormone that stimulates "flight or fight" responses, such as raised blood glucose, increased heart rate, and increased respiration rate

thyroid hormone that lowers blood calcium levels by increasing the deposition of calcium in the bones

a panceatic hormone that regulates blood glucose levels by promoting glucose entry into certain cells and promoting glucose storage

pituitary hormone that stimulates the development of mammary gland cells and production of milk

Identify the second messenger in the second messenger theory. 
A.the receptor
B.glucose
C.the hormone 
D.protein kinase 
E.cAMP (cyclic AMP) 

Steroid hormones
A.trigger the conversion of ATP into ADP 
B.bind to specific receptor molecules on the target cell membrane 
C.result in cardiovascular disease
D.diffuse through the plasma membrane of the target cell 
E.dissolve easily into the blood plasma 

The response of a target cell to a protein hormone is mediated by
A.a receptor molecule in the plasma membrane 
B.the blood cells directly influencing gene expression 
C.a receptor molecule in the cytoplasm
D.steroids in the plasma membrane 
E.an action potential 

What gland works intimately with the sympathetic division of the autonomic nervous system in combating stress?
A.testis
B.parathyroid 
C.pancreas 
D.adrenal medulla 
E.thyroid 

The hypothalamus influences the pituitary by 
A.releasing neurosecretions from neurosecretory cells whose secretory ends lie in the posterior pituitary 
B.releasing neurosecretions into the blood capillary system that connects the hypothalamus with the anterior pituitary 
C.stimulating the walls of the pituitary to contract, thus forcing hormones out of the pituitary
D.both answers "A" & "B" above 
E.answers "A", "B" and "C" above
