The Muscular System: The Ne x/ D Module 3 Interactive Homewo x Secure Login Place a single word into each sentence to make it correct lengthen contraction, the muscle During develops tension without changing in length. tense Isometric contraction occurs at the of a muscle contraction and during prolonged activities. tension During isotonic contraction, the muscle shortens even though the level ofis maintained insertion end During isotonic contraction, a be moved. can eclectic beginning The act of a muscle maintaining tension while t lengthens is called isotonic contraction. isotonic During an isotonic eccentric contraction, a muscle is allowed towithout going limp. load Reset

Explanation / Answer

1. Isometric- Isometric contractions are contractions in which no significant change in distance between origin and insertion occurs and the muscle length remains the same.

2. Beginning- it is because in the beginning the muscle adapts to the load without and change in length then the movement occurs later that result in length change

3. Tension - that is the difference. In isotonic the level of tension is maintained which however changes in Isometric contractions.

4. Load - During isotonic contractions a load can be moved. Isometric- contraction just support it from falling down.

5. Eccentric - the distance between origin and insertion increases.

6.lengthen - isotonic contraction if eccentric result in increase of length, and If concentric, result in decrease of length.
