T-type Ca+2 channels:

a) inactivate slowly
b) low abundance in cardiac cells that lack a T-tubule system (SA nodal tissue)
c) involved in cardaic pacemaker activity, growth regulation, and blocking contraction in vascular smooth muscle
d) high abundance in adult ventricular myocardium
e) T-type channels are not very sensitive to most of the L-type Ca+2 channel blockers

Answer is e:

T-type channels: Structurally similar to L-type channels; inactivate rapidly; highest abundance in cardiac cells that lack a T-tubule system (SA nodal tissue); involved in cardaic pacemaker activity, growth regulation, and triggering contraction in vascular smooth muscle; low abundance in adult ventricular myocardium
T-type channels are not very sensitive to most of the L-type Ca++-channel blockers
