endocrine system
name and describe the 3 main types of hormones + prostaglandins
1- peptide based- (amino acid +proteins ) 2-steroid-made from cholesterol 3-amine- derived from a single amino acid9non steroidal amino acids) prostaglandins- highly active lipids
main functions of the endocrine system (short answer)
1-coordinate activities of body cells 2-uses hormones as chemical messengers released into blood 3-control major processes
major processes that hormones regulate (Short answer)
1-reproduction 2-growth and development 3-mobilization of body defense 4-maintaining H2O, electrolytes, nutrients 5-regulation of metabolism regular girls(and dudes0 mean more(3) rules(men)
how many endocrine target organs are there?
6
where is the pancreas located? function?
abdominal cavity close to the stomach function=reduce blood gluclose
where is the thyroid gland located? function?
base of the throat inferior to the adams apple function=calcitonin, metabolism, tissue growth, lowers blood calcium levels
where is the pineal gland located? function?
brain back of brain function=biological rthems
compared to the nervous system, what is the main difference?
endocrine=slower
3 ways hormone glands are triggered to release
hormonal- gland to gland(activated by each other) humoral- changing of blood levels neural- nerve impulses stimulate
where is the pituitary gland located? function? (matching/ multiple choice)
inter-brain front of brain hangs below hypothalamus function= controls endocrine glands
where is the hypothalamus gland located? function?
inter-brain (center) function= nervous system,body temp,H2O,balance, regulates pituitary glands
what mechanism prompts endocrine glands to release or not to release hormones
negative feedback
where is the adrenal gland located? function?
on top of kidneys(R and L) function=raise blood gluclose
where is the ovaries located? function?
pelvic cavity(R and L) function=secondary sex characteristics
where is the parathyroid gland located? function?
posterior side of the thyroid function=PTH, raises blood calcium levels
where is the testes located? function?
scrotum outside of body function=secondary sex characteristics
2 ways which hormones trigger changes in the cells
steroid- diffuse through cell membrane,binds to receptor in cell nucleus, lipid soluable non-steroid- binds to membrane receptor, acts through second messenger system
where is the Thymus gland located? function?
upper thorax posterior to sternum function=immunity(t cells)
