dendrites and axons of intact abcs are distinguishable from one another by several ultrastructural criteria : ( 1 ) the predominance of microtubules in the dendritic cytoskeleton and neurofilaments in that of the axon , ( 2 ) the exclusively postsynaptic status of the dendrites versus the presynaptic status of the axon , and ( 3 ) the presence of polyribosomes and large numbers of mitochondria in the dendrites and their respective absence and scarcity in the axon .
