Three types of structural classification
multipolar, bipolar, unipolar
Three types of functional classification
sensory, motor, interneurons
Multipolar
1 axon, others dendrites
Bipolar
1 axon, 1 dendrite
Unipolar
2 axons
Most common type of CNS Neurons are
multipolar
Proximal process
enters CNS
Sensory
Transmit impulses from sensory receptors toward CNS
Sensory classifications are
almost all are unipolar
Where are the sensory neurons' somas found?
ganglia in PNS
Motor
Carry impulses from CNS to effectors
Motor classifications are
multipolar
Where are the motor neurons' somas found? CNS
Interneurons
lie between motor and sensory neurons
What do interneurons do?
shuttle signals through CNS pathways
