striated muscle
[L. from striare, to groove]
Skeletal voluntary muscle and cardiac muscle. The name derives from the striped appearance, which reflects the arrangement of contractile elements.

striated muscle
Contractile tissue, in vertebrates consisting of fibrils with marked striations at right angles to the long axis. The muscle is concerned with movement of skeletal parts.

The tendons of striated muscle and muscle sheaths are richly supplied. In muscle, however, their existence is still disputed.

Skeletal Muscles / Striated Muscles
Skeletal muscles are usually attached to bones. They are often called striated muscles, because of their striated, or striped appearance.

The sarcoplasmic reticulum is a special type of smooth ER found in smooth and striated muscle.

Cardiac muscle fibers are a type of striated muscle found only in the heart. The cell has a bifurcated (or forked) shape, usually with the nucleus near the center of the cell.

sarcolemma The thin, noncellular sheath that encloses a striated muscle fiber.
Sarcomastigophora The protozoan phylum where members possess flagella, pseudopodia, or both for locomotion and feeding; single type of nucleus.

The contraction of smooth muscle tends to be slower than that of striated muscle. It also is often sustained for long periods. This, too, is called tonus but the mechanism is not like that in skeletal muscle.

Actin A highly conserved protein found in all eukaryotes; in striated muscle, it forms the thin filaments of the sarcomere and activates the atpase of myosin.
