| 4. | Gliding joint | Between zygapo-physes of the successive vertebrae |
| Statement I: | Locomotory structures need not to be different from those affecting other types of movements. |
| Statement II: | All movements are locomotions, but not all locomotions are movements. |
| I: | Amoeboid |
| II: | Ciliary |
| III: | muscular |
| I: | is a specialised tissue of endodermal origin. |
| II: | contributes about 20-30 per cent of the body weight of a human adult. |

| 1. | A skeletal muscle cell is called as a muscle fibre. |
| 2. | A skeletal muscle fibre is a syncytium. |
| 3. | Sarcolemma, the plasma membrane of skeletal muscle cell, encloses the sarcoplasm. |
| 4. | Sarcoplasmic reticulum of the muscle fibres is a rough endoplasmic reticulum and is involved in excessive protein synthesis. |
| I: | Z line | an attachment point for actin molecules |
| II: | M line | an attachment point for myosin molecules |
| III: | A band | a band where only actin molecules are found |
| IV: | I band | a band where only myosin molecules are found |
| Statement I: | The portion of the myofibril between two successive ‘Z’ lines is considered as the functional unit of contraction and is called a sarcomere. |
| Statement II: | In a resting state, the edges of thin filaments on either side of the thick filaments partially overlap the free ends of the thick filaments. |
| Statement III: | The central part of thick filament, not overlapped by thin filaments is called the ‘H’ zone. |
| 1. | Statement I is correct; Statement II is correct; Statement III is correct |
| 2. | Statement I is correct; Statement II is incorrect; Statement III is correct |

| 4. | Statement I is incorrect; Statement II is incorrect; Statement III is incorrect |
| Statement I: | A single filament of tropomyosin runs close to the ‘F’ actins throughout its length. |
| Statement II: | In the resting state, a subunit of troponin masks the active binding sites for myosin on the actin filaments. |
