MUSCLE PHYSIOLOGY

Detailed explanation-1: -Skeletal muscles are made up of long and cylindrical cells. They are multinucleate (having many nuclei) and unbranched. They are also known as striated muscles because they have alternate dark and light bands. They move as per our will, hence they are categorised as voluntary muscles.

Detailed explanation-2: -Skeletal muscle fibers are cylindrical, multinucleated, striated, and under voluntary control.

Detailed explanation-3: -During development of skeletal muscle tissue, myoblasts differentiate and fuse together to form multinucleated myofibers, which are analogous to myotubes in vitro. After myofiber formation during embryogenesis, the size of individual myofibers greatly increases during the immediate postnatal period.

Detailed explanation-4: –The skeletal muscles and voluntary muscles are multinucleated.

Detailed explanation-5: -A multinucleated cell is a unique form which is frequently observed in the normal tissue. Skeletal muscle is composed of bundles of multinucleate muscle fibers [1]. Osteoclasts induce multinucleation by the cell fusion of mononuclear cells to cover a large area for bone resorption [2].
