GENERAL HISTOLOGY

Detailed explanation-1: -In a concentric contraction, the muscle tension rises to meet the resistance then remains stable as the muscle shortens. During eccentric contraction, the muscle lengthens as the resistance becomes greater than the force the muscle is producing.

Detailed explanation-2: -Muscle contracture refers to physical shortening of muscle length, and it is often accompanied by physical shortening of other soft tissues such as fascia, nerves, blood vessels, and skin.

Detailed explanation-3: -Isotonic contractions occur when the muscle changes length, producing limb motion. Concentric contractions occur when the muscle shortens. Eccentric contractions occur when the muscle lengthens.
