ch 18 pt 2 Flashcards
antagonistic effect
hormones have opposing effects
synergistic effect
hormones have an additive effect
permissive effect
1st hormone is needed for the other to produce an effect
integrative effect
hormones produce different, but complementary results
tropic hormone and examples
they act upon other endocrine glands as their target organs (FLAT)
direct hormone and examples
they act directly on non-endocrine organs (PEG)
parathyroid gland releases
paraythroid hormone which is Induced in response to LOW Blood Calcium levels
- Increases Blood Calcium levels by increasing Osteoclast activity
- antagonist to calcitonin
insulin
lowers blood glucose level
glucagon
raises blood glucose level
aldosterone function and production
produced by adrenal cortex’s zona glomerrulosa
- aids in reabsorption of sodium from the kidneys
cortisol
immunosuppressive steroid hormone produced by adrenal cortex’s zona fasciculata
progesterone function
thickens the uterine wall and maintains pregnancy
- produced in ovaries
estrogen
responsible for secondary female characteristics
- produced in ovaries
target cell
cell that responds to a specific hormone
pancreatic islets function
produce insulin
interstitial cells
cells that produce testosterone
infundibulum
the stalk of the pituitary gland
which endocrine gland also performs exocrine functions
pancreas
which part of the testes produce spermatozoa
seminiferous tubules
cells of the islets of Langerhans
alpha cells, beta, gamma cells, f cells
Endocrine secretions from which of the following adrenal regions would increase levels of sodium ions retained at the kidney?
zona glomerulosa
