Branching cells that are uninucleate and striated are typical of cardiac muscle fibers.

Explanation

Cardiac muscle is a type of striated muscle found only in the heart. Its fibers are characterized by being branched and uninucleate, which means that each muscle cell has a single nucleus, unlike skeletal muscle cells that are multinucleated. The striations in cardiac muscle are due to an organized arrangement of contractile proteins (actin and myosin), which are the same proteins responsible for muscle contraction in all types of muscle tissues. The branching nature of cardiac muscle cells allows for more interconnectedness, facilitating coordinated heart contractions, which is essential for maintaining efficient blood flow throughout the body.
