Classification of Neurons

neurons carrying impulses from sensory receptors to the CNS

dendrite endings of the sensory neurons are usually associated with specialized receptors activated by specific changes, pain receptors are the least specialized and most numerous

neurons carrying impulses from the CNS to the muscles/glands, always located in the CNS

• 
• processes extending from the cell body, most common structural type (all motor and most association neurons)

• two processes (an axon and a dendrite), rare in adults and found in only some special sense organs (eye, ea
• r)

single process emerging from the cell body, sensory organs found in the PNS ganglia are unipolar
