The capacity of a muscle cell to shorten forcefully is known as
|
|
elasticity.
|
|
|
flexibility.
|
|
|
excitability.
|
|
|
contractility.

Explanation:
Detailed explanation-1: -Contractility is the ability of muscle cells to forcefully shorten. For instance, in order to flex (decrease the angle of a joint) your elbow you need to contract (shorten) the biceps brachii and other elbow flexor muscles in the anterior arm.
Detailed explanation-2: -Concentric contraction refers to when the force of contraction exceeds the force of resistance, which results in muscle shortening and approximation of muscle origin and insertion. Eccentric contraction occurs when the force of contraction is less than the force of resistance.
