This book provides pharmacologists and biological scientists with an interest in pharmacology with an understanding of how events at the cellular level impact on the cardiovascular system as a whole. Recent advances in knowledge are highlighted, and all the themes are presented from the single cell (smooth muscle endothelial and nerve) level through to the blood vessel wall to the vascular system as a functional system. This is the first book to provide an introduction to wide-ranging pharmacological principles and major techniques in this subject area, and is an ideal source of background literature for research in vascular pharmacology.
