Skeletal muscle tissue is easily distinguished by the striation (thus also known as striated muscle). They are arranged as long cylinders and since fused from development, contain multiple nuclei within each muscle fiber/cell.
Muscle, transverse sectioned. The endomysium surrounding each muscle fiber, perimysium surrounding each fascicle and peripheral nerve can be seen.
