Synapse Structure – Foundations of Neuroscience
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).

WebElectronmicrograph of a synaptic knob separated from subsynaptic membrane of a nerve cell by a synaptic cleft (marked by arrows) about 200 Å wide. In some areas the vesicles are seen to be concentrated close to the synaptic surface of the knob, and there is an asso-ciated increase in membrane density on either side of the cleft (Palay36). edm anthem - best mix
