These are about 8 nm in diameter and, being the thinnest of the cytoskeletal filaments, are also called microfilaments. (In skeletal muscle fibers they are called thin filaments.) Some functions of actin filaments: 1  form a band just beneath the plasma membrane that.  provides mechanical strength to the cell.
Muscle tissue varies with function and location in the body. In mammals the three types are: skeletal or striated muscle; smooth or non-striated muscle; and cardiac muscle, which is sometimes known as semi-striated.n vertebrates, there is a third muscle tissue recognized: 1  Cardiac muscle (myocardium), found only in the heart, is a striated muscle similar in structure to skeletal muscle but not subject to voluntary control.
Three types of muscle tissue are cardiac, smooth, and skeletal. Skeletal muscle tissue is the only voluntary muscle, the other two are involuntary.Also, cardiac and skeletal â¦ muscles are striated.   The three main types are skeletal muscle, smooth muscle, and cardiac muscle. Skeletal muscle has a striped appearance earning its other name striated muscle. It is â¦ designed to work at a moments notice but it tires easily. Smooth muscle is not striped.
