How can muscle cell change its shape
Answers
During contraction, the muscles fibres shorten, the muscle pulls on the ligaments that connect the bones and the movable body parts. During relaxation the muscle fibres come to their original position. This movement of muscles cells or the muscle fibres results in the movement of the body parts.
Muscles have the ability to adapt to external forces, and when placed under high demand, they generate great strength and power and maintain durability. To accomplish this feat, muscles can change their shape, size, and consistency.
As muscle fibers change their size and shape, they glide over the surrounding fibers. The result is a living woven fabric capable of changing its size, shape, and strength depending on the demands of the moment.
