Answer:
the I bands to appear smaller
Explanation:
I band is the lighter and a less dense area of the sarcomere. It contains no thick filaments. A Z disc passes through the center of each I band. During muscle contraction myosin heads become attach to and slide along the thin filaments at both ends of a sarcomere. It pulls the thin filaments toward the M line and makes the thin filaments slide inward and meet at the center of a sarcomere. This inward movement of thin filament allows their ends to overlap.
As the thin filaments slide inward, I band and H zone narrower. I band and H zone become disappear altogether when the muscle is maximally contracted. The width of the A band and the lengths of the thick and thin filaments remain unchanged.
Ligaments are strips of tough tissues that serves as connective tissue for two or more bones and cartilages. These also holds the joints together. They also serve to protect and support the internal organs. Some of the most known ligaments in the body are that of the knees.
