Detailed explanation-1: -Gastrocnemius is the muscle that forms the main bulk of the calf region on the back of the lower leg. It is a bipennate muscle, meaning it has two rows of muscle fibres, facing in opposite directions with a central tendon, resembling a feather.
Detailed explanation-2: -Bipennate. Muscles that have fibers on two sides of a tendon are considered bipennate. The stapedius in the middle ear of humans, as well as the rectus femoris of the quadriceps are examples of bipennate muscles.
Detailed explanation-3: -A type of pennate muscle wherein the muscle fibers or fascicles are in opposite sides of the central tendon. Example of bipennate muscle is rectus femoris.
Detailed explanation-4: -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.
