What are Hormones? - ANSWER -Chemical transmitters that regulate
and integrate body functions by acting on local or distant target sites
-
What do hormones regulate? - ANSWER -regulate organ function in
concert with the nervous system, helping to finely regulate control of
organ functions
What hormones are released by the hypothalamus? - ANSWER -
Corticotropin-releasing hormone (CRH)
-Thyrotropin-releasing hormone (TRH)
-Growth hormone-releasing hormone (GHRH)
What is the major action of the hypothalamus? - ANSWER -controls
release of pituitary hormones
What is the major action of growth hormones? - ANSWER Stimulates
growth of bone and muscle; promotes protein synthesis and fat
metabolism; decreases carbohydrate metabolism
What is the major action of ACTH? - ANSWER -stimulates synthesis
and secretion of adrenal cortical hormones
What is the major action of TSH? - ANSWER - stimulates synthesis
and secretion of thyroid hormones
What is the hormone in the posterior pituitary? - ANSWER ADH
(vasopressin)
What is the major action of ADH? - ANSWER -increases water
reabsorption by kidneys
, Hypopituitarianism - ANSWER rare condition involving a decrease in 1
or more hormones sent from the pituitary as messengers to endocrine
glands
Oversecretion of GH can result to? - ANSWER -Giantism
-Acromegaly
Oversecretion of ACTH can result to? - ANSWER -Cushing's
(discussed with adrenal disorders)
Undersecretion of all pituitary hormones may cause? - ANSWER -
Comprises 90% of pituitary tumors
-Tumors don't produce hormones
-Tumors destroy the rest of the pituitary (can't release hormones)
-Results in hypopituitarianism (one cause of this disorder)
What is acromegaly? - ANSWER Rare condition resulting from excess
secretion of growth hormone (GH).
Results of acromegaly are? - ANSWER -excessive skeletal growth of
hands, feet, brow ridge, jaw, nose and chine
-Severe headaches
-Visual Disturbances (optic nerve pressure), including blindness
-Muscular weakness
-Decalcification of skeleton
-Sleep apnea
-Lowering of the voice
ADH disorders can result in? - ANSWER Diabetes insipidus: insufficient
ADH (don't pee hormone)
SIADH: syndrome of inappropriate ADH (excessive don't pee hormone)
What is diabetes insipidus? - ANSWER Not enough ADH, pituitary
gland
