Spinal cord Dorsal horns: Interneurons Ventral horns: Motor neurons Lateral horns: Sympathetic neurons Parasympathetic (S2-4) neurons DRG:Sensory (pseudounipolar) neurons Autonomic ganglia: Post ganglionic neurons with unmyelinated axons. Sympathetic: paravertebral ganglia Parasympathetic: In organs
