Dorsal root ganglial (DRG) neurons form muscle spindle receptors.

Dorsal root ganglial (DRG) neurons form muscle spindle receptors.
A central dorsal root projection goes directly to CNS ventral horn motoneurons. The result is a single synapse forming the path from the PNS receptor to the innervated muscle.
