Question
Which two organs are involved in the nervous system?
- Muscle and brain
- Brain and spinal cord
- Brain and blood vessels
- Nerve cells and heart
Hint:
The nervous system helps in the transmission of nerve impulses.
The correct answer is: Brain and spinal cord
- The brain and the spinal cord are the two organs involved in the nervous system.
- The nervous system refers to the system of the body which deals with the transportation of nerve impulses throughout the body. Its functional and basic unit is a neuron. The nerve impulses are usually generated with the help of external stimuli.
- The external stimulus can be in the form of touch, smell, taste, etc. This external stimulus then causes the body to generate electrical impulses which are carried to the brain or spinal cord depending on the stimulus.
- For example, in the case of touching a hot object, the nerve impulses are carried to the spinal cord via neurons whereas, in the case of memory, the nerve impulses are carried to the brain.
The neurons convert the different forms of energy from the stimulus into electrical energy.
