Uninucleated, branched, dark and light band, actin and myosin filaments, spindle-shaped cells
Options:
Answer:
A
Solution:
Skeletal muscles are also called striated or voluntary muscles. Striated muscles are attached to bones by tendons. They have long, thin, multinucleated fibres having alternate light and dark band (striations). They contain myofibrils which contain contractile proteins thin actin and thick myosin. Smooth muscle cells are uninucleate, spindle shape and don't have any striations. Cardiac muscle cells are uninucleate, show faint striations and are branched cells
