Abstract:
The lumbosacral segments of 12 spinal cords of normal new-borns and adults(Figs.1—3),and of sympodic (Figs.4—5) and diplomyeliac (Fig.6) fetuses were prepared for a microscopicstudy with special reference to the condition of the posteromedial cell column (pm).Apart fromthe 2 or 3 doubtful cases,this cell column is definitely present,which spreads dorsally and meetsits fellow across the midline in front of the central canal (cc),at S4 thus constituting a commissuralnucleus (ncs).This column possibly participates in the innervation of the pelvic and perinealmuscles which are attached to the midplane.
