Cardiac cells are long cylindrical and multinucleate. Cardiac muscle cells quickly die in the absence of oxygen. Muscle Size and Arrangement of Muscle Fascicles.

Myofibrils of cardiac muscle tissue vary in diameter and branch extensively. The plasma membranes of cardiac muscle cells interlock but skeletal muscle fibers are independent. Cardiac cells possess few mitochondria.

Skeletal muscles move in pairs 2 See answers Advertisement. Major Skeletal Muscles. They also branch in order to maintain connections.

Cardiac muscle cells must obey the all-or-none law of contraction as they always contract with the same level of force.
