The "stripes" in the muscle are called striations. Smooth muscle doesn't have the striations.

Striations are cause by pooling of blood after death in the direction of where the body originally was before being moved.My answer would be....The arrangement of myofilaments(actin/ myosin) on a myofibril produce the striations of a skeletal muscle cell . Also myofibrils align to give distinct bands. :)Hope that helps :D
The only muscle in the body that is non-striated is the smooth muscle. It does not have any visible striations.
voluntary muscles and cardiac muscles
Skeletal muscle which has microscopic alternating bands of light and dark called striations. Therefore it is striated, voluntary muscle.
The alternating A and I bands on the miofibrils.
The mature red blood cell lacks a nucleus, and so is unable to reproduce.
The heart cells are muscle, the type called involuntary muscle.
There are different types of muscle fibers. There is skeletal muscle, cardiac muscle and smooth muscle. * Skeletal muscle is attached to bones or occasionally skin. * Cardiac muscle is found in the walls of the heart. * Smooth muscle is mostly found in the walls of hollow organs such as the intestines I am currently studying anatomy and physiology at University for my nursing degree.There are three muscle Types: Skeletal, Smooth and Cardiac.All muscle cells are elongated and are called muscle fibers. Muscle contraction depends on two kinds of myofilaments (actin and myosin). The cell membrane of a muscle cell is called "sarcolemma", while the cytoplasm of a muscle cell is called "sarcoplasm".Skeletal muscle characteristics: long, thin and multi-nucleated fiber with striations, voluntary control; arranged into packages called muscles that attach to and cover the bony skeleton; contracts rapidly & vigorously, but tired easily; may exert great force.Cardiac muscle characteristics: network of branched fibers connected by gap junctions (intercalated disks); only in heart; also have striations; involuntary control; contracts at rhythmic, steady rate set by "pacemaker".Smooth muscle characteristics: lacks striations; walls of hollow visceral organs and blood vessels; involuntary control, contractions are slow & sustained.
A voluntary muscle is a muscle that work according to a person's will.Striated muscles are the muscles which have striations or the meshwork of fibres.skeletal muscles are both voluntary and striated muscles.
