Please use the word bank to complete the following statements: (choices can be used more than once, obviously) voltage-gated calcium channels voltage-gated sodium channels voltage-gated potassium channels stable not stable Unlike SA node cardiocytes, regular cardiocytes have a resting membrane potential that is Regular cardiocytes become stimulated when calcium and sodium pass fro neighboring excited cardiocytes through gap junctions (see 1). This causes to open, resulting in the regular cardiocytes to sharply depolarize (see 2). At 3, these channels close, and open, resulting in both depolarization and sarcomere contraction. Also at 3, open, causing the cell to repolarize. The opposing forces, (depolarization and repolarization) of the two channels that are open simultaneously, results in a plateau (see 4). This plateau continues until…
