Development and Underdevelopmentitzgerald (1937) noted that motoneurons are the first neurons to develop (Fig. 42). They appear in the uppermost spinal segments at approximately E27 (about Carnegie stage 13/14). At this time of development also dorsal root ganglion cells are present. Central processes of the bipolar ganglion cells

The Programming Approach to Developmentan tetrapods and mammals is the apparent absence of somatomotor cortical areas giving rise to long descending projections to the spinal cord. The phylogenetic constancy of descending supraspinal pathways, at least of those arising in the brain stem, probably implies a comparable pattern of developme
