ANSWER:

Muscles contains some special protein, they are Contractile  in nature.

EXPLANATION:

Muscle tissues are generally contractile in nature. The cells of the muscle, also called myocetes, can be shortened or returned to their original state because of this special feature.

Muscle plays a significant role in the movement of body. Although the living protoplasm of all the cells show contractility, but this characteristic is greatly enhanced in the muscle cells. This adjusts and maintains the body to the environmental changes.
