Muscle fibers can be arranged into two basic structural patterns, fusiform and pinnate. Most human muscles are fusiform, with the fibers largely arranged parallel along the muscle's longitudinal axis. In many of the larger muscles the fibers are inserted obliquely into the tendon, and this arrangement resembles a feather. The fibers in a pinnate (feather) muscle are shorter than those of a fusiform muscle. The arrangement of pinnate muscle fibers can be single or double, as in muscles of the forearm, or multipinnate, as in the gluteus maximus or deltoid.
The cardiac muscle is arranged spirally around the heart to make it more efficient.

In smooth muscle these transitionally alternating muscle fibers help to serve the actions of peristalsis. As the circular fibers contract the tube (lumen) constricts and as the longitudinal fibers contract it opens up the lumen.
