Fig. 2

80 year old specimen. A Schematic drawing of the assembled multifidus bands attached to the spinous processes of L1-L5 with their relative position in dorsal view and transversal drawings at L4 and L5 based upon the original illustrations of Macintosh et al. [17]. Each color represents a separate band, from medial to lateral, purple (L5), yellow (L4), red (L3), blue (L2) and green (L1), respectively. The transversal cross-sectional drawings show the relative positions of each band at the level of L4 and L5 vertebral bodies. B, C position in dorsal view and transversal). The yellow arrows in Fig. B. depict the level of the sagittal plane of Fig.  Coronal (B) and sagittal (C) reconstructions of the lumbosacral spine at the level of L1-S2 with demarcation line (white dotted line) between the erector spinae (ES) and the separate bands of LM (yellow numbers 1–5). L1-L5 (Fig. B), refer to the spinous processes and L1-S1 refer to the vertebral bodies (Fig. C, whereas the yellow arrows in Fig. C refer to the level of the coronal plane of Fig. B. (D1-D5) Consecutive transversal cross-sections from level S1-2 to level L3-4 from the same spine as in Figs. B and C. The numbers and colored demarcations refer to the LM bands 1–5 depicted in Figs.
