What is the basis of structural classification of neurons?
The number of processes (dendrites and axon) extending from the neuron cell body
Multipolar Neuron - appearance
*Has many dendrites and one axon
*Total number of dendrites as well as the degree of branching in those dendrites varies
Multipolar Neuron - location
*Most of the neurons within the CNS
*Most motor neurons
Bipolar Neuron - appearance
*Have two processes: one dendrite and one axon
Bipolar Neuron - function
*Dendrite is specialized to receive a specific stimulus
*Axon conducts action potentials to the CNS
Bipolar Neuron - location
*Retina of the eye
*Nasal cavity
*Bipolar neurons are rare
Unipolar Neuron - appearance
*Have a single process extending from the cell body
*This process divides into two branches a short way from the cell body
*One branch extends to the CNS
*One branch extends to the periphery and has dendrite-like sensory receptors
-This branch could be co
Unipolar Neuron - location
*Sensory neurons in the PNS
