Excitation-contraction coupling — Excitation contraction (EC) coupling is a term coined in 1952 to describe the physiological process of converting an electrical stimulus to a mechanical response [1]. This process is fundamental to muscle physiology, whereby the electrical… … Wikipedia
excitation-contraction coupling — Name given to the chain of processes coupling excitation of a muscle by the arrival of a nervous impulse at the motor end plate to the contraction of the filaments of the sarcomere. The crucial link is the release of calcium from the sarcoplasmic … Dictionary of molecular biology
Myogenic contraction — refers to a contraction initiated by the myocyte cell itself instead of an outside occurrence or stimulus such as nerve innervation. Contents 1 Mechanisms 1.1 Unstable Membrane Potentials 1.1.1 Slow wave potentials … Wikipedia
stimulus-secretion coupling — A term used to describe the events that link receipt of a stimulus with the release of materials from membrane bounded vesicles (the analogy is with excitation contraction coupling in the control of muscle contraction). A classical example is the … Dictionary of molecular biology
