Detailed explanation-1: -The extensor digitorum of the forearm is an example of a unipennate muscle. A bipennate muscle has fascicles on both sides of the tendon. In some pennate muscles, the muscle fibers wrap around the tendon, sometimes forming individual fascicles in the process.
Detailed explanation-2: -characteristics. … shoulder is said to be pennate; relatively short fibres attach diagonally onto a tendon that penetrates far into the muscle. The ankle muscles shown in Figure 4B are pennate muscles, but most of the hamstring muscles (at the back of the thigh) are parallel.
Detailed explanation-3: -The flexor hallucis longus is an unipennate muscle found on the fibular side of the posterior aspect of the leg.
Detailed explanation-4: -unipennate (not comparable) (medicine, anatomy, zoology) Of, pertaining to, or having the nature of a muscle, the parallel fibres of which attach to a tendon at an acute angle (as a feather that is barbed on one side).
