Clinically significant pathways in the spinal cord are ascending, descending and reflex axonal projections. Pathways that are especially significant are located in each of the specific quadrant zones of the spinal cord.

• Clinically significant pathways in the spinal cord are ascending, descending and reflex axonal projections. Pathways that are especially significant are located in each of the specific quadrant zones of the spinal cord.

• Ascending spinal cord pathways to understand and remember:

• Dorsal Column Pathway

• Pain Pathway

• Dorsal Spinocerebellar Tract

• Descending Spinal Cord Pathways

• Corticospinal Tract

• Rubrospinal Tract

• Medial Vestibulospinal Tract

• Pontine Reticulospinal Tract

• Medullary Reticulospinal Tract

• Lateral Vestibulospinal Tract

• Reflex Pathways

• Monosynaptic Tendon Reflexes (knee jerk)

• Flexion Reflex (withdrawal)

• Crossed Extension Reflex (swimming)

• Autonomic Somatic and Visceral Reflexes

• Startle Reflex (auditory- inferior colliculus)

• Peripheral Vision Reflex - Limb Reflex; Neck Reflex

• Babinski Reflex (pathological in adult; normal in development)
