Explain the structure of a sensory neuron.
Short dendrites with receptor cells and a long dendron with a cell body and short axon which carries nerve impulses to CNS.

Explain the structure of a motor neuron.
Short dendrites that carry nerve impulses from CNS to cell body. A long axon that carries nerve impulses from cell body to effector cells.

Explain the structure of a relay neuron.
Many short dendrites that carry nerve impulses from sensory neurons to the cell body and short axons which carry nerve impulses from cell body to motor neurons.
