ch. 19 Flashcards
endocrine tissues include
everyone
endocrine systom releases hormones into
blood, lymph, or interstitial fluid
hormones of endocrine system effectiveness
at low conc
endocrine hormone types
amines, peptides, sterioids
hypothalamus increases endocrines hormones to
be released and circulated ADH, regulatory hormones
pituitary gland is a fusion of
2 tissue types
posterior lobe and anterior lobe
hormones released by posterior lobe of pituitary gland are called
neurohormones
neurohormones include
ADH and oxytocin
ADH helps increase
blood volume and pressure
oxytocin stimulates contraction of muscles in
prostate and uterus and mammary
neurohormones are packaged in
vesicles
anterior lobe of pituitary gland produces
trophic hormones
how many trophic hormones
7
anterior lobe of pituitrary gland secrete by
inhibit/release neurohormones from hypothalamus
hypophyseal portal system is in the
anterior lobe of pituitaery gland
hypophyseal portal system carries
neurohormones from the hypothalamus to the anterior pituitary
tsh is released by
anterior pituitary
acth targets
adrenal cortex
gensofrophrine hormone does
follicile stimulating
prolactin stimulate
milk and immune
growth hormone does
tissues, muscles, growth
msh causes
meloncytes to reproduce melon
see most in fetus stuff
thryoid is locating
anterior to trachea and inferior to larynx
thryoid gland is two lobes connected by
isthmus
thryoid made up of tiny
thyroid follicles
fluid in thyroid
colloid
colloid helps with
thyroid synthesization
c thyrocyte cells produce
calcitonin
t3 t4 released
tonically
stress prolonged
in adults thyroids helps with
oxidative metabolism
children need thryoid production for
growth hormone
symptoms of thyroid problems
goiter:mass on neck/thyroid
myxedema: bags under eyes
exophthalmos: bulging of eyes
paraythyroid gland is how many structures
4
parathyroid located
posterior surface of thryoid gland
parapthryoid prinicpal cellsproduce
PTH
PTH
increases ca2 levels in blood
thymus is embedded in
connective tissue
thymus is below the
sternum
thymus is large in
infants and decrease with age
thymus produces hormone
thymosin
thymosin involved with
develop and mature of t lymphocytes
adrenal cortex produces
24 steroid hormones
three zones of adrenal cortex
zona glomerulosa
zona fasciculata
zona reticularis
zona glomerulosa produces
aldosterone
zona fasciculata produces
corotozol
zona reticularis produces
androgens
adrenal medualla contains
chromaffin cells
adrenal medulla secretes
epinephrine and nonepephrine
androgens includes
testostorone
most female testostorone comes from
adrenal glands
endocrine tissue P
pancreas
pancreatic islets produce
hormones
pancreatic islets hormons
alpha
beta
delta
f cells
alpha cells produce
glucagon
beta cells produce
insulin
delta cells produce
somatostatin
f cells produce
pancreatic polypeptide
diebetes mellitius is characterized by
hyperglycemia
rare 10% diebetes
type 1
type 1 dibates is when
immune system targets and estroys b cells of pancreas
type 2 diabetes is when
insulin conc is normal but insulin receptors are desenitized
short term proplems of diabetes
debhydration
ketoacidosis for type 1
hormones produced by kidneys
renin
erythropoietin
calcitriol
renin
primary horomone in pathway increases blood pressure
erhtyropoietin increases
red blood cells in response to low blood pressure
calcitriol secretes
ca2 in gi tract
hormones produced by heart
atrial natriuretic peptide
brain natriuretic peptide
ANP and BNP target
lowering blood pressure
