WebThe cardiac myocyte is a specialized striated muscle cell that is approximately 25 μ in diameter and about 100 μ in length. They form a branching network of cells that are connected by intercalated discs. The … WebMuscle tissue is a soft tissue that is primarily composed of long muscle fibers. The coordinated interaction of the myofilaments actin and myosin within the myocytes gives muscle tissue the ability to contract. Depending on the intracellular arrangement of these myofilaments, muscle tissue is classified as either striated (skeletal and cardiac) or …
WebExcitation-contraction coupling (ECC) is the process whereby an action potential triggers a myocyte to contract, followed by subsequent relaxation.
