Question

Brain is the structural and the functional unit of the nervous system?
A. True
B. False

Answer 1

Hint: Nervous system mainly consists of neurons that are the structural and functional unit. Brain is the part of the nervous system which comes under the classification of the central nervous system.

Complete answer:
Brain is the structural and the functional unit of the nervous system. It is a false statement as the nervous system mainly consists of neurons which are structural and functional units of the nervous system. These are the only cells which help in transmission of nerve impulses from the effector area to the brain and the process input from the brain to the effector organs to generate output like responses. It works like computer operating system cells are the input and the signals imparting are the output.

Hence, Brain is the structural and functional unit of the nervous system will be the false statement.

Additional Information: The nervous system consists of brain and spinal cords as the main parts and all other sensory organs and nerves connected to the body. This connection makes the whole framework of the nervous system which helps in the control and communication process.

Note:
Neurons are the backbone of the nervous system. As it is the only single primary cell also called nerve cells having a central body called soma and other extensions of axons and the dendrites. Former one is the large extension of nerve cells known as the transmitters, consisting of myelin sheath. Dendrites are the small extension that acts as a receiver of stimuli. Neurons form the connection to create networks that influence all voluntary and involuntary activities.
