Detailed explanation-1: -In a neuron or a nerve cell, the impulse travels through the axon towards the axonite. The dendrite of the receiving neuron picks up this impulse which is again transferred to another neuron or a cell. Hence, axon transfers the signal/impulse and the dendrite receives the impulse from other neurons.
Detailed explanation-2: -An axon, or nerve fibre, is a long slender projection of a nerve cell, or neuron, that conducts electrical impulses away from the neuron’s cell body or soma.
Detailed explanation-3: -The dendrites serve to receive incoming electrical signals from other neurons. Most neurons have a single axon to transmit outgoing signals. Axons vary in length from micrometers to over a meter. Portions of the axon are insulated by supporting cells with myelin, a phospolipid membrane.
