Figure 6.4: Myelin-Stained Sections through Different Levels of the Spinal Cord

Figure 6.4 A: An illustration shows a transverse aspect of the spinal cord, indicating the cervical enlargements C 3 to T 1 and lumbosacral enlargements L 1 to S 2 with section levels. The parts shown are cervicomedullary junction, cervical cord, thoracic cord, lumbar cord, and sacral cord. Figure 6.4 B: An image shows the dorsal aspect of the cervicomedullary junction indicating the spinal trigeminal tract, dorsal columns, dorsal horn, and pyramidal decussation. Figure 6.4 C: An image shows the dorsal aspect of the cervical cord, indicating the dorsal nerve root, lateral column, dorsal columns, Lissauer's tract, dorsal horn, lateral motor nuclei, or limb muscles, and ventral horn. Figure 6.4 D: An image shows the dorsal aspect of the thoracic cord indicating the dorsal horn, nucleus dorsalis of Clark, dorsal columns, Lissauer's tract, lateral column, intermediolateral cell column, or preganglionic sympathetic. Figure 6.4 E: An image shows the lumbar cord's dorsal aspect, indicating dorsal nerve roots, ventral nerve roots, ventral horn, and dorsal horn. Figure 6.4 F: An image shows the dorsal aspect of the sacral cord, indicating dorsal nerve root, dorsal horn, and ventral horn.
