differentiate between axon and dendrite.
Answers
Axon:
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.
Dendrite:
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

Dendrite refers to the ‘Trees‘ in Greek, so these are the branched small extension of the nerve cell. Axon refers to the ‘axis‘ in Greek, so axon is the long slender like protrusion of the neuron or nerve cell.
Secondly, dendrite receives messages or information or electrochemical impulses from the external environment or other neurons, so they work as the input for the neuron. The role of the axon is to send messages or any information or electrochemical impulses to the external environment or other neurons. So they are the output for the neuron.
