Calcium-Induced Calcium Release (CICR) Within Cardiac Myocytes Excitation-contraction coupling occurs within cardiac muscle cells in response to calcium-induced calcium release, CICR.

Calcium movement is central to the process of excitation–contraction coupling in cardiac myocytes. 3 Membrane depolarization results in the entry of calcium via the L-type calcium channel (see ...

However, recent results in humans and animals suggests that myocyte replication does indeed occur under both physiological and pathological conditions of the heart, which raises the possibility ...

Heart myocytes are narrower and much shorter than skeletal muscle cells, with many mitochondria that produce the energy needed for all of that beating over a lifetime.

Heart muscle excitation-contraction (E-C) coupling is governed by Ca²⁺ release units (CRUs) whereby Ca²⁺ influx via L-type Ca²⁺ channels (Cav1.2) triggers Ca²⁺ release from juxtaposed Ca²⁺ release ...
