is the gluteus maximus fusiform
The fibers in a pinnate muscle are typically 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 (figure 2.1).he basic function of muscle is to generate force. Secondarily, muscles can provide some shape and form to the organism. Anatomically and functionally, muscle can be divided into two types, smooth and striated.
