Q

function of parathyroid hormone

A

calcium homeostasis. stimulates kidneys to reabsorb Ca2+, activates vitamin D so calcium can be absorbed from small intestines, stimulates osteoclasts when calcium levels are low

25
what does epinephrine do
increases heart rate and bronchodilates
26
what does norepinephrine
vasocontricts peripheral arteries to increase blood pressure
27
where are corticosteroids released from
adrenal cortex
28
what are corticosteroids and where are they released from
lipid based hormones made from cholesterol. adrenal cortex
29
what are the corticosteroids
mineralcorticoids, glucocorticoids, gonadocorticoids
30
what do mineralcorticoids do
regulate elecotrolytes in the body
31
what type of corticosteroid is aldosterone
mineralcorticoid
32
what does aldosterone do
stimulated by low blood pressure, holds on to sodium to increase H2O volume to increase blood pressure
33
what do glucocorticoids do
regulate glucose levels during stress
34
what are the glucocorticoids
cortisol and cortisone
35
what does cortisol do
using gluconeogenesis (making glucose from lipids or proteins in the liver) increases blood glucose
36
what do gonadocorticoids do
are androgens that are precursers to testosterone and estrogen. sex drive and armpit hair at puberty
37
what is the pancreas' exocrine function
relese bicarb into small intestine to make chyme less acidic and enzyme rich digestive juices for digestion
38
endocrine function of the pancreas
hormones that regulate blood glucose levels
39
what do pancreatic islets do
clusters of cells that serve endocrine function
40
what cells are found in the pancreatic islets
alpha and beta cells
41
what do pancreatic alpha
produce hormone glucagon
42
what do beta cells do in pancreas
produce insulin
43
what does glucagon do
liver catabolizes glucagon into glucose which is released into blood to increase glucose levels
44
what does insulin do
insulin targets body cells to uptake glucose to decrease levels of glucose in blood
45
what does estrogen do and what is it secreted by
by ovaries, sex organ development and body hair
46
what does progesterone do
breast development and uterine cycles
47
what does testosterone do and what is it secreted by
testes. development of sex organs, body hair, muscle mass and sex drive, sperm development
48
what does the thymus do
lymphocyte maturity
49
what does thymosin do and where is it secreted from
thymus. acts on T lymphocytes that are developing immunocompentence; chooses/trains T cell lineage
50
which endocrine organ shrinks as we age and is replaced with connective tissue
thymus
51
what secretes melatonin
pineal body/gland
52
what does melatonin do
responsible for sleep/wake cycle. more released at night to promote sleeping and light inhibits melatonin
