A motor unit is

A type of strength training in which the joint angle and muscle length do not change during contraction is termed as:

1. isometric contraction.

2. isotonic contraction.

3. concentric contraction.

4. eccentric contraction.

With respect to slow twitch [Type I] fibers the fast-twitch [Type II] muscle fibers are:
1. More resistant to fatigue.
2. Supplied by more more blood vessels.
3. Having Larger amount of stored glycogen.
4. Having more mitochondria.

In smooth muscle contraction:
1. Calcium ions bind to troponin C.
2. Myosin has no role.
3. Troponin and tropomyosin are moved.
4. Calcium ions bind to calmodulin, which activates an enzyme.
