Highly coordinated contractions of cardiac muscle pump blood into the vessels of the circulatory system. ... However, cardiac muscle fibers are shorter than skeletal muscle fibers and usually contain only one nucleus, which is located in the central region of the cell.

Cardiac muscle fibers have a single nucleus, are branched
