Clin Med Exam 2 Endocrine Complete Questions With
Complete Answers
/. what is stress - Answer-✅real or perceived threat to homeostasis
/.when stress occurs, what does the endocrine system do (2) - Answer-✅increase
release of cortisol from adrenal cortex
increase release of epinephrine from adrenal medulla
/.what does cortisol permit - Answer-✅permits actions of epi and norepi on smooth
muscle cells around blood vessels
/.what does cortisol's permission on epi/norepi result in - Answer-✅control blood
pressure
/.why is cortisol referred to as a glucocorticoid - Answer-✅it maintains cellular
concentrations of metabolic enzymes that are required to produce glucose btw meals
and prevents low blood glucose
/.what does cortisol decrease - Answer-✅decrease events of inflammatory response
such as capillary permeability and production of prostaglandins
/.cortisol allows for.... - Answer-✅proper fetal development
/.what is crh - Answer-✅corticotropin releasing hormone
/.where does crh come from - Answer-✅hypothalamus
/.what does crh do - Answer-✅Stimulates the production and release of ACTH
/.what is acth - Answer-✅adrenocorticotropic hormone
/.where does acth come from - Answer-✅anterior pituitary
/.what does acth do - Answer-✅increase cortisol secretion
/.where does cortisol come from - Answer-✅adrenal cortex
, /.increased plasma cortisol will lead to what - Answer-✅negative feedback to
hypothalamus and anterior pituitary
/.what do increased plasma cortisol concentrations do to protein - Answer-✅stimulates
protein catabolism
/.what does increased plasma cortisol concentrations do to the liver - Answer-
✅stimulates liver uptake of amino acids and their conversion to glucose
/.what does increased plasma cortisol concentration help maintain - Answer-✅plasma
glucose concentrations
/.what does increased plasma cortisol concentration do to adipose tissue - Answer-
✅stimulate triglyceride catabolism in adipose tissue and release glycerol and fatty acids
into blood
/.what does increased plasma cortisol concentration do to vascularization - Answer-
✅enhanced vascular reactivity, increased ability to maintain vasoconstriction from
norepi
/.what does increased plasma cortisol concentration inhibit (2) - Answer-✅inhibits
inflammation and specific immune response
inhibit nonessential functions
/.adrenal insufficiency results in... - Answer-✅plasma cortisol levels chronically lower
than normal
/.what are symptoms of adrenal insufficiency (3) - Answer-✅weakness
fatigue
loss of appetite/weight
/.what can examination of adrenal insufficiency reveal and why - Answer-✅low bp since
cortisol can't emphasize effect of epi
low blood sugar since cortisol can't normalize metabolic actions
/.what is the cause of primary adrenal insufficiency - Answer-✅loss of adrenocortical
function
/.what diseases can cause primary adrenal insufficiency - Answer-✅infectious diseases
like tuberculosis
/.how do infectious diseases cause primary adrenal insufficiency - Answer-✅they
infiltrate adrenal glands and destroy them
