Answer 2

First let us know about reflex action

The automatic action or response provoked by a stimulus is known as a reflex action.

• The reflex actions, however, show sudden responses and do not involve any thinking.

• When we accidentally touch a hot object, we withdraw our hands immediately without thinking.

• If we do not do this, our hands will burn.

• The sensory nerves detect the heat.

• They are connected to the nerves, which move the muscles of the hand.

Reflex Arc

Such a connection of detecting the signal from the nerves (input), and responding to it immediately (output) is called a reflex arc.

• A reflex arc makes instant and automatic responses possible.

• It connects the input nerve and output nerve, and meets in a bundle in the spinal chord.

• In fact, nerves from all over the body meet in a bundle in the spinal cord, on their way to the brain.

• Therefore, the information input reaches the brain.
