Calcium channel blocking drugs reduce the risk of heart disease.
The calcium channels are rapidly inactivated, soon after they open.
Calcium channels are also present in the smooth muscle that lines blood vessels.
The depolarization of the membrane allows calcium channels to open as well.
The T-type calcium channel is found in neurons throughout the brain.
Some of its activity may involve interaction with voltage-gated calcium channels.
Cadmium can be used to block calcium channels in chicken neurons.
This change in the cell's membrane potential causes voltage-gated calcium channels to close.
Many cells have calcium channels on their surface.
Hyperpolarization of the cell causes voltage-gated calcium channels to close.
