Isotonic Definition Anatomy

In chemistry a solution is said to be isotonic when it has the same concentration of solutes as another solution across a semipermeable membrane. Of a motion in the direction of contraction of a muscle.

Isotonic And Isometric

The distance between the origin and insertion becomes lessened.

Isotonic definition anatomy. Isotonic definition isotonic is a term used to describe solutions and chemistry and sometimes muscles in human biology. Postural contraction the state of muscular tension and contraction that just suffices to maintain the posture of the body. Isotonic of a fluid that exerts the same osmotic pressure as another especially as that of the body fluids.

Isotonic exercise is one method of muscular exercise. Isotonic contractions are those where the muscle changes length as it contracts whilst the load or resistance remains the same. Isotonic contraction isotonic literally means same tension where iso means the same and tonic refers to tension or force in this case in the muscle.

As a result this causes movement of a body part. In contrast isometric exercise is when muscular contractions occur without movement of the involved parts of the body. Isotonic movements are either concentric working muscle shortens or eccentric working muscle lengthens.

There are two types of isotonic contraction. Start studying anatomy hypotonic isotonic hypertonic. Learn vocabulary terms and more with flashcards games and other study tools.

Lengthening contraction eccentric contraction. Water moves out of the cells. Of or involving muscular contraction against resistance in which the length of the muscle changes.

Isotonic contraction muscle contraction without appreciable change in the force of contraction. The outside of the cells have a lower concentration than on the inside which has a higher concentration. Body cells such as red blood cells can be immersed in an isotonic solution without being caused to change shape.

Isotonic comes from the greek iso equal tonos tone maintaining equal muscle tone.
