WebDiad. Within the muscle tissue of animals and humans, contraction and relaxation of the muscle cells ( myocytes) is a highly regulated and rhythmic process. In cardiomyocytes, or cardiac muscle cells, muscular contraction takes place due to movement at a structure referred to as the diad, sometimes spelled "dyad." WebThe cardiac action potential is a measurement of the membrane potential waveform of the cardiac myocytes signifying the electrical activity of the cell during the contraction and relaxation of the heart.

WebMyocytes ("muscle cells") conduct signals and cause parts of the animal to contract. "Grey cells" act as sponges' equivalent of an immune system . Archaeocytes (or amoebocytes ) are amoeba -like cells that are totipotent , in other words, each is capable of transformation into any other type of cell. WebContraction band lesions, a.k.a. myofibrillar degeneration, coagulative myocytolysis, kinetic cell death, and contraction band necrosis, can be regarded as accelerated necrosis of irreversibly injured myocytes. They represent hypercontraction with massive influx of calcium within injured myocytes which were still viable prior to reperfusion.
