What is coordination?
1. It is the process through which two or more organs interact and complement the functions of one another
2. It is the process of serving tissues
3. It is the process of giving blood and masses to other tissue at the level of structure
4. It is the ratio of functional and non functional organs
| Assertion (A): | All the organs in our body work in a synchronised function |
| Reason (R): | Neural and endocrine systems jointly coordinate and integrate all the activities of organs |
| 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. |
| 1. | A well-developed brain with ganglia and neural tissues |
| 2. | A network of neurons without any organised structure |
| 3. | A central nervous system and peripheral nervous system |
| 4. | Myelinated nerve fibers arranged in a hierarchical manner |
| 1. | All the activities of the organs |
| 2. | Only secretory activities of glands so that they function in a synchronised fashion |
| 3. | Only muscular activities of the muscles |
| 4. | Only activities of the vital organs |
| Assertion (A): | The neural system of Hydra is better organised than insects. |
| Reason (R): | Insects have a brain along with a number of ganglia and neural tissues. |
| 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, (R) is False. |
| 4. | (A) is False, (R) is True. |
Visceral nervous system:
| 1. | is a part of PNS |
| 2. | is made up of Nerves, Fibres, Ganglia and Plexuses |
| 3. | transmits information from CNS to the viscera and viscera to CNS |
| 4. | All of the above |
| 1. | Somatic nervous system |
| 2. | Autonomic nervous system |
| 3. | Spinal nerves |
| 4. | Afferent division of PNS |
| Statement I: | The central nervous system consists of the brain and spinal cord. |
| Statement II: | The peripheral nervous system consists of cranial nerves and spinal nerves. |
| 1. | Somatic controls voluntary muscles, autonomic controls involuntary organs |
| 2. | Somatic controls sensory functions, autonomic controls motor functions |
| 3. | Somatic controls conscious activities, autonomic controls reflexes |
| 4. | Somatic controls cranial nerves, autonomic controls spinal nerves |
