Answer 2

Answer:

Reflex action is a sudden, unconscious and involuntary response of the effectors to the stimulus. Example of such a sudden stimuli is touching a hot substance.

Such reflex actions are controlled by spinal cord or the peripheral nervous system.

The information about the stimulus and the response is send to the brain after the response are given by the effectors.

The pathway of a reflex action is called reflex arc.

• In a reflex arc the stimulus is received by receptors are the sense organs.

• The stimulus passes through sensory nerves to the spinal cord.

• The spinal cord gives the information of the response that is to be given to the stimulus.

• The information about the response passes through the motor nerves.

• The response is given to the stimulus by the factors or the muscles and glands.
