Skeletal Muscle Cells

Question

Skeletal muscle cells
A) have a single nucleus
B) have branching fibers
C) have cross striations
D) are spindle-shaped or have tapered ends
E) have intercalated disks

Accepted Answer

Skeletal muscle cells, also known as muscle fibers, have cross striations due to the organization of contractile proteins into sarcomeres. They are long and cylindrical in shape and typically have multiple nuclei per cell. Branching fibers and intercalated disks are features of cardiac muscle cells, while spindle-shaped or tapered ends are features of smooth muscle cells.
