The critical event for the contraction of striated muscles would be that calcium ions:
1. | are released from troponin C |
2. | bind to tropomyosin |
3. | bind to troponin |
4. | are taken up by the sarcoplasmic reticulum |
Cross bridge formation during muscle contraction involves:
1. | troponin and actin | 2. | tropomyosin and myosin |
3. | myosin and troponin | 4. | myosin and actin |
The fibrous joint between skull bones is called as:
1. | gomphoses | 2. | syndesmoses |

Given below are two statements: one is labelled as Assertion (A) and the other is labelled as Reason (R):
Assertion (A): | Smooth muscle is fundamentally different from skeletal muscle and cardiac muscle. |
Reason (R): | Smooth muscle is an involuntary non-striated muscle. |
In the light of the above statements choose the correct answer from the options given below:
1. | Both (A) and (R) are True and (R) is the correct explanation of (A). |
2. | Both (A) and (R) are True but (R) is not the correct explanation of (A). |
3. | (A) is True but (R) is False. |
4. | Both (A) and (R) are False. |
The Z line is present in:
1. | A band | 2. | H zone |
3. | I band | 4. | M line |
The correct statement regarding myofibril would be:
1. | It is the name for a muscle cell. |
2. | It contains sarcoplasmic reticulum. |
3. | It is made up of many sarcomeres. |
4. | It is a bundle of muscle cells. |
