Thoracic, Lumbar and Sacral

Sections of 3-D Model

Figure 11. A continuation of the previous fi gure showing outlines of the sections used in the thoracic, lumbar, and sacral spinal cord. Six of these sec-
tions are illustrated in the Atlas. Section 1593 is in Plate 17; section 1884 is in Plate 18, section 2134 is in Plate 19, and sections 2607 and 2674 are in
Plate 20. After fi xation, the total length of the thoracic part of the model (Figure 14) is 6.99 mm and the combined lumbar and sacral regions is 6.66 mm
(Figure 15).
