Definition
circadian pattern - highest levels are in am follwoing acth release

increased coritosl produciton:

physiological: stress excercise, pregnancy.

patholgoical: psuedo cushings (continous stress all the time pyhysiolgoical state 24/7), acth depepndant andi ndepepndant, and exogenosu soruces
Term
pseudocushigns mechanism
