AXON |
DENDRITE |
|
|
|
|
Each neuron has only one axon |
Each neuron has many dendrites |
|
Axon is present on the side of the neuron that conducts impulses to the next neuron |
Dendrite is present on the side of the neuron that receives impulses from previous neuron |
|
Axon conducts impulses away from the particular neuron |
Dendrites receive impulses from previous neuron |
|
Axons can reach up to several metres in length |
Dendrites are usually around and less than 1.5mm in length |
|
They have branches only at the terminal end |
They are branched all through |
|
They have a uniform thickness throughout the length |
Due to branching, the thickness varies |
|
The terminal branches of axon have synaptic knob (structure that have chemicals called neurotransmitters to pass on impulses to next neuron) |
They do not have synaptic knob |
|
It is always covered in a sheath |
It is not covered in a sheath |
