Detailed explanation-1: -60.3). Pennate muscles can be further subdivided into unipennate (e.g. flexor pollicis longus), bipennate (e.g. rectus femoris, dorsal interossei), multipennate (e.g. deltoid), and circumpennate or cylindrical (e.g. tibialis anterior).
Detailed explanation-2: -If all the fascicles of a pennate muscle are on the same side of the tendon, the pennate muscle is called unipennate. If the fascicles lie to either side of the tendon the muscle is called bipennate. If the central tendon branches within a pennate muscle, the muscle is called multipennate.
Detailed explanation-3: -If all the fascicles are on the same side of the tendon, the pennate muscle is called unipennate (Fig. 1A). Examples of this include certain muscles in the hand. If there are fascicles on both sides of the central tendon, the pennate muscle is called bipennate (Fig.
Detailed explanation-4: -A type of pennate muscle wherein the muscle fibers or fascicles are all in one side of the tendon. Example of unipennate muscle is extensor digitorum longum.
Detailed explanation-5: -Definition noun A type of pennate muscle wherein the diagonal muscle fibers are in multiple rows with the central tendon branching into two or more tendons.
