Ascending And Descending Tracts Of Spinal Cord Ppt [top]

The spinal cord tracts are categorized into ascending (sensory/afferent) and descending (motor/efferent) pathways that allow the brain to communicate with the rest of the body. 1. Ascending Tracts (Sensory Pathways)

The spinal cord's white matter consists of bundled axons organized into long columns called ascending and descending tracts of spinal cord ppt

• Ascending tracts: carry sensory information from the body to the brain
• Descending tracts: carry motor information from the brain to the body

Slide 14: Summary Table of Major Tracts

| Tract | Type | Crosses | Function | |-------|------|---------|----------| | Lateral Spinothalamic | Ascending | Spinal cord | Pain, temp | | Dorsal Column | Ascending | Medulla | Fine touch, vibration | | Lateral Corticospinal | Descending | Medulla | Voluntary movement | | Vestibulospinal | Descending | No | Balance, extensor tone | The spinal cord tracts are categorized into ascending

Structure & slide count

1. Title slide — "Ascending & Descending Tracts of the Spinal Cord" (subtitle: course/name/date)
2. Learning objectives — 3 bullet points: identify major tracts, describe pathways and functions, clinical correlations
3. Spinal cord overview — brief anatomy diagram (cross-section) with gray/white matter labeled
4. White matter organization — dorsal, lateral, ventral columns; general flow (sensory up, motor down)
5. Ascending tracts — slide header + short list of principal tracts:
   • Ipsilateral loss: proprioception & motor below lesion
   • Contralateral loss: pain & temperature beginning ~2 levels below lesion
