Spinal Cord Nuclear Columns

• Longitudinal limits of spinal cord nuclei

• Sensory

• Substania Gelatinosa- Pain & light touch Path; Entire cord
• Nucleus Proprius- Entire cord length- pain, touch, temp, cerebellar.
• Clarkes Column- T1-L2 Dorsal spinal cerebellar tract (DSCT).
• Intermediate nuclear column- Visceral sensory T1 - L 2; receiving reflex afferents

• Motor

• Dorsal medial column & Ventral Medial column- Trunk musculature
• Ventral horn- Brachial plexus (C5-C8 ) and lumbosacral plexus(L4-S3) enlargements
• Preganglionic Sympathetic- Intermediate nuclear motor column- Visceral motor; T1 - L 2
