047 Action Potentials and Contraction in Cardiac Muscle Cells

http://www.interactive-biology.com - Making Biology Fun http://www.interactive-biology.com/community/ - Get your BIology Questions Answered In this episode I show how the Action potential is generated in cardiac muscle cells and how this results in Contraction of the Heart. When the action potential happens, calcium ions are released from the Sarcoplasmic reticulum, causing the plateau. Calcium ions then trigger muscle contraction. http://www.interactive-biology.com
