GENERAL HISTOLOGY

Detailed explanation-1: -Isometric. Isometric movements are muscle contractions that do not cause your joints to move. Your muscles are activated, but they are not required to lengthen or shorten. As a result, isometric contractions generate force and tension without any movement through your joints.

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: -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.
