we say that electrical impulse travels via neuron in which it travels from the dendrite along axon to its end and how does the electrical impulse returns back from brain?
Does it travels via neuron aga
TRAVALLING OF ELECTRICAL IMPULSE
nerve inmpulse travel as electric irritablity in a neuron always from dendrites to cyton to axon to axon end to dendrite of next neuron n so on as neurons r connected end to end with each other in nerve fibres. it never travels fromaxon to dendrite of same newuron .
when impulse travels from sense organs to brain it travels through sensory nerves consisting of sensory neurons n when it travels from brain to efectors it travels through motor nerves consisting of motor neurons
