Which of the Following is FALSE Regarding Skeletal Muscle Fibers

Question

Which of the following is FALSE regarding skeletal muscle fibers (cells)?
A) Each fiber is a single cell with a hundred or more nuclei.
B) The cells are cylindrical and are arranged in parallel fashion.
C) A skeletal muscle fiber may be up to 30 cm (12 in.) long.
D) The myofibrils are arranged at right angles to the long axis of the cell, creating cross striations.

Accepted Answer

The myofibrils in skeletal muscle fibers are arranged parallel to the long axis of the cell, not at right angles. This parallel arrangement contributes to the characteristic striated appearance of skeletal muscle under a microscope.
