WebSynaptic Knob: The axon terminal branches are enlarged to form synaptic knobs at the tips known as end bulbs. No synaptic knobs occur at the tips of the branches of the dendrites. Myelin Sheath: Axons can be either medullated or non-medulated (have a myelin sheath). Dendrites are usually non-myelinated (Non-medullated)/ (do not have myelin sheath).
