Which of the Following is Descriptive of Skeletal Muscle Fibers

Question

Which of the following is descriptive of skeletal muscle fibers?
A)Skeletal muscle fibers lack a sarcolemma and myofibrils.
B)Skeletal muscle fibers are striated.
C)Skeletal muscle fibers are smaller than most cells.
D)Skeletal muscle fibers are uninucleate.

Accepted Answer

Skeletal muscle fibers are striated, meaning they have a striped appearance due to the arrangement of contractile proteins. They have a sarcolemma (plasma membrane) and contain myofibrils, which are responsible for muscle contraction. Skeletal muscle fibers are larger than most cells and are multinucleate.
