Hey Friend,
Reflex arc - the nerve pathway involved in a reflex action, including at its simplest a sensory nerve and a motor nerve with a synapse between.
Explanation -
There are certain responses which need not to be processed by the brain and need to be responded immediately!
Such responses occur at the level of spinal cord. The response that occurs at the level of spinal cord without the brain knowing about it is called reflex action.
The path through which the stimulus travels is called reflex arc.
(The diagram is given below in the attachment)
Nerve Impulses flow in one direction only. This is because nerve cells only have neurotransmitters storage vesicles going one way and receptors in one place. Thus, impulses can't travel in opposite direction!
Hope it helps!
