MUSCLE PHYSIOLOGY

Detailed explanation-1: -Skeletal muscles and cardiac muscles are called striated muscles due to the presence of alternate dark and light bands. When stained, this arrangement is visible as light and dark bands under the microscope. Hence, striations appear on striped muscles.

Detailed explanation-2: -What do skeletal muscles look like? Skeletal muscle fibers are red and white. They look striated, or striped, so they’re often called striated muscles. Cardiac muscles are also striated, but smooth muscles aren’t.

Detailed explanation-3: -Which is true of the light bands in skeletal muscle? D. They are called M lines and represent the interaction of the myosin filaments and Z discs.
