ANATOMY

Detailed explanation-1: -A contraction is the act of decreasing the size of something or shortening it, or it can be the process of becoming smaller or compressed.

Detailed explanation-2: -Muscles are fibrous tissues that has the ability to contract. Muscles contract and relax resulting in movement of limbs. Muscles become shorter, stiffer and thicker when it contracts. It becomes longer and thinner on relaxation.

Detailed explanation-3: -A concentric contraction is a type of muscle contraction in which the muscles shorten while generating force.

Detailed explanation-4: -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.

Detailed explanation-5: -Capable of being made to shrink.
