Abstract:
During sympathetic nerve activity, sympathetic transmitter causes depolarizations which trigger voltage dependent Ca++ entry. The ability of arteriolar membranes to sum together successive e.j.ps is changed as a consequence of cellular activity, i.e. increased [K+]o. Furthermore, the ability of arteriolar membrane to permit voltage dependent Ca++ entry is modified by a second consequence of cellular activity, i.e. changes in external pH.
