why do voluntary muscles striate?

Open in App

Solution

The voluntary muscles are striated because long and thin fibres (myofibrils) of these muscles have a regular pattern of alternating dark and light bands. The dark band contains the protein myosin and is called the A band (anisotropic band) and light band contains the protein actin and is called the I band (Isotropic band).
