WebbProprioceptive neurons are pseudounipolar with a single axon that extends from the cell body and splits into two branches. One branch innervates peripheral receptive tissues to read changes in body position, while the other projects toward neural targets in the spinal cord to relay this information onto spinal or supraspinal sensory-motor circuits.
