CALCIUM CHANNEL

n. an ion channel which is selectively-permeable to calcium ions. These ions carry electrical charges back and forth through this channel, particularly along the presynaptic membrane of neurons. Thus, this channel and its ions participate in the release of neurtransmitters.

CALCIUM CHANNEL: "The calcium channel is an electrically-charged channel through which calcium ions are able to pass."
