Question

Neural system and computers share certain common features. Comment in five lines. (Hint: CPU, input-output devices).

Answer 1

Common features :

• The brain and spinal cord form the central neural system of our body and process all the information like the CPU in the computer.
• The sense organs of our body give input signals to the central nervous system like input devices, keyboards and mouse of the computer.
• Eyes,ear, nose,tongue and skin bear receptors on sense neurons to receive any change in the body and give input to CNS to process it and give an output through motor neurons accordingly.
• Example -Eyes have photoreceptors and lenses to construct and view the image, it gives the signal to CNS for the processing and gives output of an image. It works like a camera on the computer.

Summary:

Analogous part	Neural system	Computers
Main processor	CNS	CPU
Input device	Sense organs	Keyboard, mouse etc
Output device	Through Motor neurons to effectors	Monitor, printer
