How big are muscle cells
WebCardiac muscle cells, like skeletal muscle cells, have a highly developed SR system. Excitation–contraction coupling in cardiac muscle cells is similar to that in skeletal muscle cells. Specifically, an action potential travels down the T tubules and causes the release of Ca2+ from the SR, which in turn activates the contractile machinery by ... WebThe part of the neuron that needs the calcium is very close to the surface of the neurons membrane, so thats where it needs to draw in calcium. The sarcoplasmic reticulum is deep within the muscle cell, cause thats where the troponin are that need the calcium.
