12Bipolar neuron Classifications
One dendrite that branches one axon with cell body inbetween
13psedudounipolar Neuron Classification
Dendrite and axon are continuous with cell body branch off the axon
14Multipolar neuron
Have 2 or more dendrites a single axon with cell body between
15What do Pseudounipolar Neruons help with?
Deliever information from the peripheral sensory receptors to the CNS
