GENERAL HISTOLOGY

Detailed explanation-1: -Isometric contractions are contractions in which there is no change in the length of the muscle. No joint or limb motion occurs. Isotonic contractions occur when the muscle changes length, producing limb motion. Concentric contractions occur when the muscle shortens.

Detailed explanation-2: -Isometric exercises are tightening (contractions) of a specific muscle or group of muscles. During isometric exercises, the muscle doesn’t noticeably change length. The affected joint also doesn’t move. Isometric exercises help maintain strength.

Detailed explanation-3: -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-4: -Isotonic contractions are those in which there is consistent tension as the muscle length changes. These can be either concentric (muscle shortening) or eccentric (muscle elongation). Isometric contractions are those in which the length of the muscle does not change.
