Figure 2

Schematic representation of the dendroarchitecture of spinal motoneurons in various motor columns. The ventromedial motoneurons (IX-vm) form vertical and longitudinal dendritic branches (not shown), motoneurons in the ventrolateral (IX-vl) and central (IX-c) columns tend to form dendritic bundles in the longitudinal and transverse planes. Motoneurons in these columns have long overlapping areas. On the contrary, dorsolateral motoneurons (IX-dl) have no such a dendritic bundle formation and their branches mostly branch out in the transverse plane. WM: white matter; DF= dorsal funiculus; DH= dorsal horn; CC= central canal.
