Ascending And Descending Tracts Of Spinal Cord Ppt [work] ❲No Ads❳

Understanding the Anatomy and Physiology of Spinal Cord Tracts

• Posterior (Dorsal) Funiculus: Contains ascending tracts only (fine touch, vibration, proprioception).
• Lateral Funiculus: Contains both ascending (spinothalamic, spinocerebellar) and descending (corticospinal, rubrospinal) tracts.
• Anterior (Ventral) Funiculus: Contains both ascending (spinothalamic – anterior part) and descending (vestibulospinal, reticulospinal, tectospinal) tracts.

Slide 12: Clinical Case – Brown-Séquard Syndrome (Hemisection)

• Cause: Trauma, tumor (one side of spinal cord).
• Ipsilateral findings (same side):

  Tips for Your PPT Design

  • Colors: Use red for ascending tracts, blue for descending tracts, green for decussation points.
  • Animations: Show tracts “building” stepwise (first-order → second-order → thalamus → cortex).
  • Diagrams: Include cross-sections at cervical, thoracic, lumbar levels.
  • Fonts: Minimal text – use bullet points and talk around them.

  Slide 2: Introduction to Spinal Cord Organization ascending and descending tracts of spinal cord ppt

• General Rule: Most tracts cross over (decussate) to the opposite side of the brain (contralateral control).

• Located medially.
• Carries input from the lower limb and lower trunk (below T6).
