Presentation Transcript

  1. تنظیم و بازنگری :دکتر مهران مرادی رزیدنت جراحی مغز و اعصاب • Anatomy of the Spinal Cord •  Structure of the spinal cord • Tracts of the spinal cord • Spinal cord syndromes Won Taek Lee, M.D., Ph.D.

  2. Spinal Cord - Comparable to Input-Output (IO) System of the Computer - Spinal Nerve (C8, T12, L5, S5, Cx1) - Segmental Structure of Neural Tube Origin

  3. Spinal segment C8, T12, L5, S5, Cx1 Anterior (Ventral) Root Posterior (Dorsal) Root Dorsal Root (Spinal) Ganglion Root - Rootlets

  4. Spinal Cord External Figure Conus Medullaris (L1-2) Spinomedullary Junction - Foramen Magnum, Pyramidal decussation, C1 ventral root Enlargements - cervical (C5-T1) & lumbosacral (L1-L4) Longitudinal Fissures - anterior median fissure - anterolateral fissure - posterior median sulcus - posterolateral sulcus

  5. Conus Medullaris (L1-2) Cauda Equina Anterior median fissure Anterolateral fissure

  6. Posterior median sulcus Posterolateral sulcus Posterior intermediate sulcus Fasciculus cuneatus Fasciculus gracilis Posterior surface of the spinal cord

  7. Spinal Cord Meninges Periosteum of Vertebra - Epidural Space ----------------- epidural anesthesia Dura Mater Spinalis Arachnoid Membrane - Subarachnoid Space -------- Lumbar Puncture Spinal Anesthesia Pia Mater Spinalis - Denticulate Ligament --------- Cordotomy - Filum Terminale

  8. Meninges of • the spinal cord • Dura mater • Arachnoid membrane • Pia mater Denticulate ligament - specilization of the pia mater - landmark for cordotomy

  9. Meninges of the spinal cord

  10. Meninges of the spinal cord

  11. Lumbar Puncture – lumbar (terminal) cistern

  12. Spinal Cord Vascular Supply Arterial Supply - Spinal Arteries Anterior (1) & Posterior (2) Spinal Artery from Vertebral artery - Radicular Arteries ----- Segmental arteries from Vertebral, Ascending Cervical, Intercostal and Lumbar Artery Venous Drainage - Longitudinal & Radicular Veins to Intervertebral veins ---- to Internal Vertebral Venous Plexus to external vertebral venous plexus ---- to segmental veins

  13. 5. Adamkiwicz artery anterior spinal artery segmental arteries
