a.Sarcoplasmic reticulum of the muscle fibres is the storehouse of calcium ions.
b.The type of muscles present in our thigh are striated and voluntary.
c.The H-zone in the skeletal muscle fibre is due to the central gap between myosin filaments in the A-band.

14. Role of calcium during muscle contraction is that
1. It exposes F-actin by conformational change in troponin
2. It increases affinity of myosin for ATP
3. It binds to actin binding site on myosin
4. It prevents contraction of sarcomere


15. Match the Column-I with Column -II

4. More blood capillaries

18. Select the incorrect statement among the following:
1. A cup-shaped bone called patella covers the knee dorsally.
2. The number of wrist bones present in each forelimb is equal to the total number of cranial bones in an adult human.
3. The number of cervical vertebrae are seven in most mammals including human beings.
4. Vertebral column has a central hollow portion (neural canal) through which the spinal cord passes.


Arrange the following events involved in muscular contraction
(i) Action potential enters muscle fibre through T-tubules
(ii) Ca2+ binds with troponin-C
(iii) Actomyosin cross bridge formation
(iv) Sliding of thin myofilament along the thick myofilament
