Different parts of the muscle (such as the medial and lateral muscle bellies) are often innervated by separate branches. There may be 1-6 branches, but are usually 2-3. These may connect within the muscle. This innervation modality may indicate that the different parts of the muscle can be activated

The muscle is directed superiorly and laterally from its origin to its insertion. The muscle's fibres vary in orientation superoinferiorly: the superior-most fibres are nearly horizontally oriented, the intermediate fibres are obliquely oriented, and the inferior-most fibres are nearly vertically
