How does the structure of the skeletal muscle help it perform its function? Its spindle-shaped cells allow it to do smooth movem
ents. Its striations allow for big movements. Its nucleated cells allow it to trigger involuntary actions. Its discs allow it to coordinate movement with other cells.
Muscle cells perform important functions in the living organisms. They perform the function of support, movements and controls the body coordination. Three different muscles are skeletal muscle, cardiac muscle and smooth muscle.
Skeletal muscles are attached to bones that involves in the entry and exit side of the body. The skeletal muscles shows striations and has many nuclei that allows the large movements of the body. These striations involves the sarcomere units that allows the body contraction.
The right answer is Its striations allow for big movements.
*Skeletal muscle is by definition the muscle that, through the tendon, attaches to the skeleton and allows the movement of the skeleton in a well-defined direction thanks to its essential function of contraction. It has been described, with the first optical microscope observations on tissue in longitudinal section, as a tissue having both transverse and longitudinal striations. Muscle fibers are plurinucleate cells of polygonal shape whose nuclei are located at the periphery of the fiber, attached to the sarcoplasmic membrane. A skeletal muscle fiber is a true syncitium, ie a set of protoplasm fused together. The striated skeletal muscle fiber therefore has the functional characteristics of a giant cell (1-5 cm long, 10-100 μm in diameter).
*Skeletal muscle is a voluntary contraction muscle. Each of the fibers constituting it is a structural syncytium. The intensity of muscle contraction as a whole is a function of the number of motor units that have been activated.
