Patterns of alpha-adrenoceptor regulation of the vasculature.

There are patterns in the distribution of the characteristics of vascular alpha-adrenoceptors. Sudden changes in their mechanism occur at particularly sites along the main branches of the aorta; in some regional vascular beds, but not others, there is a progressive reduction in the response that can be elicited through the alpha-adrenoceptor; in smaller… CONTINUE READING
