Spinal Cord

• Spinal Cord

• Dorsal Column/ Medial Lemniscus Pathway

• Function- Specific Tactile, Vibratory, Stereognosis
• Somatotopic mapped
• Cord (dorsal columns)- medial to lateral stacking for caudal to rostral addition
• Medulla (medial lemniscus) - ventral to dorsal=caudal to rostral
• Pons (medial lemniscus) - lateral to medial= caudal to rostral
• Midbrain (medial lemniscus) - lateral to medial= caudal to rostral
• Thalamus (VPL)- lateral to medial= caudal to rostral

• Brainstem

• Chief Sensory Nucleus Pathway of 5th Nerve- i.e. Medial Lemniscus

• Function- Specific Tactile, Vibratory, Stereognosis on face & head
• Somatotopic
• Dorsal Trigeminal- Thalamic tract
• Thalamus- VPM (Ventral posterior medial)
