ANATOMY

Detailed explanation-1: -Striated muscle tissue is a muscle tissue that features repeating functional units called sarcomeres. The presence of sarcomeres manifests as a series of bands visible along the muscle fibers, which is responsible for the striated appearance observed in microscopic images of this tissue.

Detailed explanation-2: -Medical Definition striated muscle. noun. : muscle tissue that is marked by transverse dark and light bands, that is made up of elongated fibers, and that includes skeletal and usually cardiac muscle of vertebrates and most muscle of arthropods compare smooth muscle, voluntary muscle.

Detailed explanation-3: -The striated appearance of skeletal muscle tissue is a result of repeating bands of the proteins actin and myosin that are present along the length of myofibrils. Dark A bands and light I bands repeat along myofibrils, and the alignment of myofibrils in the cell causes the entire cell to appear striated or banded.

Detailed explanation-4: -Muscles that show alternate light and dark bands or striations when stained appropriately. (that’s why these are called striated muscles). Tissues are long, cylindrical, unbranched and multinucleated (having many nuclei).

Detailed explanation-5: -Skeletal muscles are long and cylindrical in appearance; when viewed under a microscope, skeletal muscle tissue has a striped or striated appearance. The striations are caused by the regular arrangement of contractile proteins (actin and myosin).
