1) Structure of a Neuron 2) Types of Neuron -Unipolar (pseudounipolar) – single, short process -Multipolar – three or more processes -Pyramidal – neurons with a pyramidal-shaped cell body (soma) and two distinct dendritic trees -Bipolar – two processes (axon and dendrite) -Purkinje – have multiple dendrites that fan out from the cell body 3) Types of Neuroglia in PNS Satellite cells – Surround the nerve cells of ganglia – Flattened cells with prominent nuclei – Insulate & support neurons of ganglia ▪ Schwann cells – Form myelin sheath in the peripheral nervous system – Flattened cells with a flattened nucleus
