Camera lucida drawings of dendritic trees of fore- and hindlimb moving motoneurons (MNs) of frogs. Neurons are from the 3rd cervical and the 8th or 9th lumbar segments as seen in the transverse plane of the spinal cord. Drawings of MNs were superimposed with the contours of spinal cord to show locations of somata and direction and extent of dendrites. Dashed lines mark the border of white and gray matters. Scale bars are 100 μm. Part of this Figure was reprinted from  and  with permissions of the publishers Elsevier and John Wiley & Sons.
