PLEASE HELP!!! In skeletal muscle, calcium ions leave the terminal cistern via the: a. DHP receptor b.Nicotinic ACh receptor c.Ryanodine receptor d.Calcium ATPase e. Voltage-gated calcium channel​
Calcium ion release from the SR, occurs in the junctional SR/terminal cisternae through a ryanodine receptor (RyR) and is known as a calcium spark.
