Question

How are reflex action performed?explain it with the help of a diagram

Answer 1

Reflex action is the action that is performed without involvement of brain.
That is, it is controlled by spinal cord.
For example, When we touch a hot cup of tea, we act as fast as possible to take back our hand in order to prevent burning. This action is performed without the involvement of brain. Performed by spinal cord, reflex actions are aided by motor nerves.
