Difference between Axon and Dendrites


Difference between Axon and Dendrites


Distinguish, differentiate, compare and explain what is the main difference between Axon and Dendrites. Comparison and Differences.

A neuron has three main parts. The cell body directs all activities of the neuron. Dendrites extend out from the cell body and receive messages from other nerve cells. An axon is a long single fiber that transmits messages from the cell body to the dendrites of other neurons or to other body tissues, such as muscles. A protective covering called the myelin sheath, covers most neurons. Myelin insulates the axon and helps nerve signals travel faster and farther.

Difference between Axon and Dendrites

S.No. Axon Dendrites
1 Found single per neuron. Usually found many per neuron.
2 Arises from a conical projection, the axon hillock, from the discharging end of a neuron. Arises directly from the receiving surface of the neuron.
3 They are very long (may be several meters) and of uniform diameter (0.25 -over 10 mm). They are very short(generally under 1.5 mm) and tapering.
4 Axon is branched at the distal end only. Dendrites much branched, practically all along.
5 With axons, terminal branches enlarged to form synaptic knobs at the tips. Have no knobs at the tips of the branches.
6 Has neurotransmitter containing vesicles in the knobs. Do not have such vesicles anywhere.
7 Conduct impulses away from the cyton. Conduct impulses towards the cyton.
