Endocrine System Flashcards
endocrine system function
maintains homeostasis by regulating the production of chemicals that affect most function of the body
Endocrine glands are—–
ductless glands
glands secrete what
hormones
where do hormones travel through
bloodstream
where does bloodstream carry hormones to
target tissue
What are endocrine conditions due to
hypo or hyper secretion of hormones
hypo
to little
hyper
too much
pineal glands release
melatonin which regulates sleep
pituitary gland is located in
sella turcia
pituitary gland is
master gland that controls other glands
hypothalamus
nervous system, releases hormones that regulate pituitary gland
Isthmus
connects right and left lobes in the thyroid gland
T3 and T4
regulate metabolism
calcitonin
lowers blood calcium levels
parathyroid glands
raise blood calcium levels via parathyroid hormone
adrenal glad
produces cortisol which is an anti-inflammartory hormone
adrenal medulla secretes
catecholamine
catecholamine
epinephrine-fight or flight
adrenal cortex
outer
adrenal medulla
inner
beta
releases insulin when BS is high (to lower it)
Alpha
releases glucagon when BS is lower (to raise it)
ovaries
produce female hormones, estrogen
testes
produces male hormones, testosterone
Pituitary abnomalities
acromegaly and syndrome of inappropriate ADH
acromegaly
hypersecretion of growth hormones causing gigantism
syndrome of inappropriate ADH
hyper secretion of antudiuretic hormone, causes excessive water retention, producing adema in the body
hyperthyroidism
graves disease, overactive thyroidsecretion causing bulging eyes
ACTH
adrenocorticotropic
ADH
Antidiuretic hormone
CRH
corticotropin-releasing hormone
DM
diabetes mellitus
FSH
follicle-stimulating hormone
GH
growth hormone
GTT
glucose tolerace test
HCG
human chorionic gonadotrpin
IDDM
insulin dedpendant diabetes mellitus
LH
luteinizing hormone
MSH
melanocyte stimulating hormone
NIDDM
nonisulin dependant diabetes mellitus
PRL
prolactin
PTH
parathyroid hormone
STH
somatotropin hormone
TSH
thyroid stimulating hormone
feedback loop
hypothalamus produces corticotropin-releasing hormone (CRH) that stimulates the pituitary gland to secrete adrenocorticotropin hormone (ACTH). ACTH then stimulates the adrenal glands to make and release cortisol hormones into the blood.
