WebWe examined the relationships among structure, contractile function, and calcium kinetics in these isolated cardiomyocytes. The cardiomyopathic myocytes were wider and longer than controls, and myopathic cells were less calcium tolerant. WebThese tissues include the skeletal muscle fibers, blood vessels, nerve fibers, and connective tissue. Each skeletal muscle has three layers of connective tissue (called mysia) that enclose it, provide structure to the muscle, and compartmentalize the muscle fibers within the muscle ( Figure 10.2.1 ).
