Enlarged 2500x. This model shows the structures that combine to form the functional neuron. The durable,molded plastic model is designed in tow sections ,the perikaryon cut open to expose the nucleus of the cell,neurite cone,dendrites and flexible synaptic terminals;and the peripheral nerve with sheaths,inluding the Schwann cell with nucleus,the Schwann sheath, the neuraxon and mitochondria. in all there are 14 keyed strutcures.
