Nerve impulse direction flow diagram
WebAll the nerve fibres carry information in the form of nerve impulse. Nerve impulse is the sum total of physical and chemical disturbances created by a stimulus (electrical, chemical or mechanical) in a neuron or nerve fibre which result in the movement of a wave along the nerve fibre.
