Question

Briefly explain the reflex action.

Answer 1

Reflex action is defined as a instant response to stimulus. This is an automatic response to a particular stimuli. There is action performed which is mediated by the reflex arc. The movement is rapid and very quick. This is a type of involuntary movement which results in voluntary action. The impulse generated at the sensory receptors is carried by the sensory neuron to the brain or the spinal cord. The information is analysed and the response is carried by the motor neuron to the effector organ.

Example is when you touch a hot object, there is movement of the muscles in hand and the hand is moved away from the source of heat.
