What is Reflex Arc? Draw neat diagram of the components in a reflex arc. Why do impulses flow only only in one direction in a reflex arc?

1- THIS IS THE STUCTURE OF REFLEX ARC

•  The automatic / involuntary action which are under the control is called Reflex Action. The pathway Reflex Action is called Reflex Arc.

•  The automatic / involuntary action which are under the control is called Reflex Action. The pathway Reflex Action is called Reflex Arc.

The simplest form of response in the nervous system is called reflex action and the pathway taken by nerve impulses in a reflex action is called reflex arc.

 Nerve impulses can't travel in opposite direction because nerve cells only have neurotransmitter storage vesicles going one way and receptors in one place.

The pathway followed by nerve impulses to transmit the message to the receptors and then carry it back to the effector muscle cells in response to a stimuli is called reflex arc.
