Which muscle go into fatigue?
1 Striped
2 Unstriped
3 Cardiac
4 Involuntnary
Explanation:
Skeletal muscle(striped muscles) get fatigue.

The H-Zone in the skeletal muscle fibre is due to
1 The central gap between actin filaments extending through myosin filaments in the A-band
2 Extension of myosin filaments in the central portion of the A-band.
3 The absence of myofibrils in the central portion of A-band
4 The central gap between myosin filaments in the A-band.
Explanation:
As per sliding filament theory, during muscle contraction, actin and myosin filaments slide over each other by formation of cross bridges and reduce length of a sarcomere. As the muscle contracts, Z-lines come closer, width of 'I' band and ' H 'band decreases. But there is no change in length of ' A ' band.

Each organised skeletal muscle in our body is made of a number of
1 Muscle bundles
2 Fascicles
3 Both 1 and 2
4 Sarcomere
Explanation:
Each organised skeletal muscle in our body is made of a number of muscle bundles or fascicles held together by a common collagenous connective tissue layer called fascia.
