Question

What are the differences between axons and dendrites?

Answer 1

Dendrite:

1. Dendrites are branched or unbranched structures arise from cyton.

2. These carry impulse towards the cell body.

3. Dendrties devoid of myelin sheath and are not insulated.

4. Nissl's granules are neart he site of origin Node of Ranvier absent.

5. Dendrites are small.

Axon:

1. Axons are branched at the tail ends.

2. They carry impulse away from the cyton.

3. They may be myelinated or non-myelinated.

4. Nissl's granules absent and node of Ranvier present.

5. These are long and big in size.

Answer 2

Differences Between Axons and Dendrites

Explanation:

Both Axons and Dendrites are parts of a neuron and conduct nerve impulses.  Please find the differences between them below and also in the attached image as a table.

Axon

1. Only one Axon per neuron
2. Discharging end
3. Longer (sometimes several metres)
4. Uniform length
5. Enlarged synaptic knot
6. Only neurofibrils, no Nissl's granules
7. Conducts neural impulse away from soma

Dendrite

1. Many dendrites per neuron
2. Receiving end
3. Shorter (under 1.5 mm)
4. Highly branched
5. No such structure
6. Both neurofibrils and Nissl's granules
7. Conducts neural impulse towards the soma
