What is the excitation contraction coupling?
Excitation contraction coupling is the process by which an electrical stimulus triggers the release of calcium by the sarcoplasmic reticulum, initiating the mechanism of muscle contraction by sarcomere shortening.

Excitation contraction coupling is the process by which an electrical stimulus triggers the release of calcium by the sarcoplasmic reticulum, initiating the mechanism of muscle contraction by sarcomere shortening. From: Neuromuscular Case Studies, 2008.Click to see full answer. Subsequently, one may also ask, what is required for excitation contraction coupling?Excitation-contraction coupling involves the transformation of depolarizing events in the sarcolemma into the initiation of mechanical shortening of the myofibrils within the myofiber by calcium ions released from the terminal cisternae of the sarcoplasmic reticulum (SR).Secondly, what is the process of excitation? The process of excitation is one of the major means by which matter absorbs pulses of electromagnetic energy (photons), such as light, and by which it is heated or ionized by the impact of charged particles, such as electrons and alpha particles. what is the excitation portion of excitation contraction coupling? Excitation–contraction coupling is the physiological process of converting an electrical stimulus to a mechanical response. It is the link (transduction) between the action potential generated in the sarcolemma and the start of a muscle contraction. Figure 38.4F.How does excitation contraction coupling differ in cardiac and skeletal muscle?Cardiac muscle fibers contract via excitation-contraction coupling, using a mechanism unique to cardiac muscle called calcium -induced calcium release. Excitation-contraction coupling describes the process of converting an electrical stimulus ( action potential ) into a mechanical response (muscle contraction).
