PDF-In excitable cells, including neurons, voltage-gated cal

cium channels VGCCs also known as Ca V s respond to a depolarization of membrane potential by allowing Ca 2 entry This response provides Ca 2 for many processes including neurotransmitter. x Muscle cells and x nerve cells neurons are excitable The color photo courtesy of Julie H Sandell and Richard H Masland is of a single inter neuron in the retina of a rabbit The cell has been injected with a f luorescent dye to reveal all its branc April 11, 2014..
