    why are arterioles less responsive to the constrictor effects of catecholamines in the absence of cortisol?

    This question is in conjunction to Addison's disease.

    I've always thought cortisol was a steriod involved in sugar metabolism.

    ...can it be because, assumably less CH20 is made (ex. glucose) which would inadverently effect the amount of Na ion's transported in a cell (glucose/Na co-transport) thus rendering less AP potentiated, w/c in this case is the blood vessels that have adrenergic (catecholamines) receptors from which upon stimulation causes vasocontriction?
