Cardiac muscle cells differ from skeletal muscle cells in that: A. skeletal muscle cells are voluntary but cardiac muscle cells are not. B. skeletal muscle cells are branched but cardiac muscle cells are not. C. cardiac muscle cells are multinucleate but skeletal muscle cells are not. D. cardiac muscle cells are a syncytium while skeletal muscle does not
Option A. Skeletal muscle is voluntary, at the same time as cardiac muscle isn't under our aware control. A skeletal muscle cell is a syncytium (composed from the amalgamation of many small cells (myoblasts) even as the myocardium behaves as a functional syncytium – the cells contract in unison.
