Difference Between Axon and Dendrites

The nerve cell has two very distinct and important components called axons and dendrites. These two parts of the cell are responsible for relaying electrical signals with other nerve cells. Read on to explore how these two structures are different from each other and the specific function they perform

Difference Between Dendrites and Axons

Axons

Dendrites

Number

Only one axon per nerve cell

Many dendrites in a nerve cell

Arises From

The discharging end of a neuron

The receiving end of a neuron

Length

Longer than dendrites

Comparatively shorter than axons

Thickness

Uniformly thick throughout its length

Edges taper off into branch-like structures

Neurofibrils

Present

Present

Nissl’s Granules

Absent

Present

Direction of Conduction

Conducts impulses away from the cell body (soma)

Conducts impulses towards the cell body

The terminal branches end in a knot

Knots are not formed
