Answer:
Contractility
Explanation:
Muscle tissue is made up of cells that can contract so as to produce movement of the body parts. It is largely cellular and rich with blood vessels. Actin and myosin are contractile proteins that are located in the muscle tissue. It is grouped into skeletal muscle tissue, smooth muscle tissue, and cardiac muscle tissue.
Contractility is the capability of muscle cells to forcefully undego reduction in length. E.g., flexing(deduction in the angle of a joint) results in elbow contraction (shorten), the biceps brachii and the varying elbow flexor muscles in the anterior arm. Another example is the extension of elbow that involves contraction of the posterior arm extensor muscles. This explains why muscles majorly pull but can't push.
