endocrine Flashcards
(35 cards)
neck glands
thyroid and parathyroid gland
gland behind chest bone
thymus
leptin released from where
leptin (decreases appetite)
up regulation
more receptors to catch hormones more efficiently and can also change the sensitivity
down regulation is the opposite because there are lots of hormones available
lipid soluble hormones
need a lipid to get into the cell
water soluble hormones
bind to outside of the cell and starts the effect of the hormones
synergistic effects
need 2 hormones needed to make effect
permissive effects
2 hormones can work independently but have a better together
antagonist effects
hormones work against each other (insulin vs. glucagon)
synergysm example
testosterone needs FSH for normal sperm production
antagonism example
during pregnancy progesterone inhibits uterine response to estrogen
permissiveness example
thyroid hormone increases the effect of epinephrine
most hormones controled by what??
negative feedback
the infindibulum is what??
connects the hypothalamus and pituitary gland
posterior pituatary does what??
stores hormones made by hypothalamas
adenohypophysis
anterior lobe pituitary
neurohypophysis
posterior lobe of pituitary gland
hypophysio portal system does what
allows hormone communication between hypothalamas and pituitary
human growth hormone hGH
most plentiful in anterior pituitary
2 hormones stored in the posterior pituitary
oxytocin and antidiuretic hormone
thyroid division
left side
sithmus
right side
follicular cells stimulated by what
TSH and release T3 and T4
thyroid gland helps with what
metabolic function
TRH stands for what??
thyroid tropin releasing hormone
