sensory
37
What is the structure of multipolar neurons?
One axon, multiple dendrites coming from cell body (multiple processes)
38
What is the structure of bipolar neurons?
Cell body with 1 dendrite at one end and one axon at the other (2 processes)
39
What is the structure of unipolar neurons?
Cell body with one axon from end to end (1 process)
40
Where are motor neurons found?
ventral horn
41

dorsal horn
42
What is the area between the ventral and dorsal horns called?
intermediate substance
43

Dorsal horn just before it merges with the ventral horn
44
Where are the cell bodies of sensory neurons found?
In the dorsal root ganglion of the dorsal horn
45
What are perikaryon?
Neuronal cell bodies
46
What are dendrites?
Projection from the soma of the neuron
47
What are axons?
Long projection from the soma of the neuron that conducts APs away from the cell body
