hypothalamus hormones
CRH, TRH, GHRH
CRH
corticotropin-releasing hormone
TRH
thyrotropin-releasing hormone
GHRH
growth hormone-releasing hormone
anterior pituitary hormones
GH, ACTH, TSH
GH
growth hormone
function of GH
stimulates growth of bone and muscle; promotes protein synthesis and fat
metabolism; decreases carbohydrate metabolism
ACTH
adrenocorticotropic hormone
function of ACTH
stimulates synthesis and secretion of adrenal cortical hormones
TSH
thyroid stimulating hormone
function of TSH
stimulates synthesis and secretion of thyroid hormones
, posterior pituitary hormones
ADH/vasopressin
ADH/vasopressin
antidiuretic hormone
function of ADH/vasopressin
increases water reabsorption by the kidney
hypopituitarism
hyposecretion of one or more pituitary gland hormones
causes of hypopituitarism
tumor, infarction, trauma, radiation
panhypopituitarism
loss of all pituitary hormones
collaborative care of hypopituitarism
treat cause; replace deficient hormones; educate patient on replacement
hormones and S&S of abnormalities
acromegaly
oversecretion of GH
when does acromegaly occur?
in adulthood, after growth plates close
most common cause of acromegaly
pituitary tumor
manifestations of acromegaly
excessive skeletal and tissue growth; severe headaches; visual disturbances;
muscular weakness; decalcification of skeleton; sleep apnea; lowering of voice
collaborative care of acromegaly
