Document Summary
A neuron with one axon and many dendrites. 3 types of multipolar neurons (purkinje, stellar, pyramidal); Stellar/stellate: found throughout cerebral cortex as well as the cerebellum. Pyramidal: found throughout the cortex as well as subcortical areas and corticospinal tract, primarily excitatory, implicated in plasticity . Purkinje: amongst the largest of the cns neurons, found in the cerebellum. Neuron with one axon and one dendrite attached to its soma. A neuron with one axon attached to its soma; the axon extends from the soma and/or divides, with one branch receiving sensory information and the other sending the information into the central nervous system. Receptor neurons, sensitive to certain kinds of stimulation. Conducts impulses to muscles and glands from the spinal cord. Dendrites and axon remain within a single structure. Neurons are supported functionally and structurally in both the cns and pns.
