How a muscle contraction is signalled
Web17 de jan. de 2024 · In cardiac, skeletal, and some smooth muscle tissue, contraction occurs through a phenomenon known as excitation contraction coupling (ECC). ECC describes the process of converting an electrical stimulus from the neurons into a mechanical response that facilitates muscle movement. Action potentials are the … WebConcentric. Concentric contraction involves shortening of the muscle with requisite movement of the origin or insertion and limb translation.9 Athletes use concentric contractions to counter a load. They are used to accelerate the distal segment of the limb and attached equipment, such as a racquet or ball. With skill training, the ball can be ...
