Solution:
Muscle is an organ that contracts and helps in movement. The anatomical unit or structural unit of a muscle is a single muscle cell. Since it is thin and long, it is also called muscle fibre. The functional unit or contractile unit of muscle is a sarcomere present in the myofibril within a muscle fibre. It is the distance between two consecutive Z lines.
