A cytoarchitectonic scheme for the spinal cord of the domestic fowl, Gallus gallus domesticus: lumbar region.

In Nissl stained and silver impregnated transverse sections of the chick spinal cord it is possible to subdivide the gray matter of the lumbar region into ten cytoarchitectonically discrete regions or laminae. The laminae are basically similar in both brachial and lumbar regions of the chick cord, with minor exceptions in the dorsal horn. The laminar scheme postulated for the chick cord is , with the exception of the glycogen body and orientation of laminae 1, 2 and 3 in the dorsal horn, similar to the laminar scheme proposed by Rexed (1954) for the cat.
