![]() ![]() Some axons are myelinated to speed up the transmission of nerve impulses. The diameter of an axon is uniform while dendrites consist of tapering ends. Both axons and dendrites transmit nerve impulses. ConclusionĪxon and dendrite are the two types of projections of a nerve cell. Afferent/EfferentĪxon:Axons form the efferent component of the nerve impulse.ĭendrite: Dendrite form the afferent component of the nerve impulse. Direction of the TransmissionĪxon: Axons carry nerve impulses away from the cell body.ĭendrite:Dendrites carry nerve impulses towards the cell body. Myelinated/Non-myelinatedĪxon:Axons can be either myelinated or non-myelinated.ĭendrite:Dendrites are non-myelinated. Nissl’s GranulesĪxon:Axons do not contain Nissl’s granules.ĭendrite: Dendrites contain Nissl’s granules. ![]() VesiclesĪxon:The synaptic knobs of the axons contain vesicles with neurotransmitters.ĭendrite:Dendrites do not have vesicles that contain neurotransmitters. Synaptic KnobsĪxon:The tips of the terminal branches of the axon are enlarged to form synaptic knobs.ĭendrite: No synaptic knobs occur at the tips of the branches of the dendrites. Branchingĭendrite:Dendrites are branched all along. Diameterĭendrite: Dendrites have tapering ends therefore diameter continuously decreases. LengthĪxon: Axons are very long (several meters).ĭendrite: Dendrites are very short (around 1.5 mm). OriginĪxon: An axon arises from a conical projection called axon hillock.ĭendrite:Dendrites arise directly from the nerve cell. Numberĭendrite:A nerve cell has many dendrites.
