WebCardiac Muscle Cells (Myocytes) Cardiac tissue is only found in the walls of the heart chambers, where it provides the muscle contractions required to pump blood throughout the body. At the tissue level, cardiac muscle is striated (or striped) since, like skeletal muscle, it has organized sarcomeres. WebThe myocytes are surrounded by a rich network of blood vessels and capillaries and are embedded in a matrix of connective tissue. Also present in this matrix are nerves and lymphatics, as well as mast cells, histiocytes, fibroblasts, pericytes, and poorly differentiated mesenchymal cells. kurs i coaching
