Both Axon and Dendrite are processes of a neuron, however, they have some contrasting characters as described below.
- Only one axon is present in a neuron.
- It is a thin long process of uniform thickness and smooth surface.
- The branches of axon are fewer and at right angles to the axon.
- Axon contains neurofibrils and no Nissl’s granules.
- It forms the efferent component of the impulse.
- Dendrites are usually multiple in number in a neuron.
- These are short multiple processes. Their thickness diminishes as these divide repeatedly. The branches are studded with spiny projections.
- The dendrites branch profusely and are given off at acute angles.
- Dendrites contain both neurofibrils and Nissl’s granules.
- Dendrites form the afferent component of the impulse
