The lumbar spinal cord segment of the one-humped camel (Camelus dromedarius) embryos at 2.4- to 28-cm crown vertebral rump length (CVRL) was examined. Major changes are occurring in the organization of the lumbar spinal cord segment at this early developmental period. At first, the spinal cord is flattened from side to side but with increase in gestational age it becomes flattened dorsoventrally. The size and shape of the lumen changes in indifferent stage of development. These changes may be in relation to the decrease of ependymal layer and increase of the mantel layer during the developmental stages. The lumen of the spinal cord is a wide spindle in shape at 2.4-cm CVRL, diamond in shape at 5.5-cm CVRL and narrow oval in shape at 28-cm CVRL. It occupies about the whole, half and one-seventh of the total height of the spinal cord at 2.4-, 5.5- and 28-cm CVRL, respectively. At the 2.4–2.7 CVRL, the spinal cord is formed of six plates: roof, floor, two alar and two basal plates. The present investigation indicates that the distribution of the ependymal, mantle and marginal layers differs in the various developmental stages of the camel embryos. The majority of the cross section of the spinal cord consists at first of ependymal and mantle layers, and a thin outer rim of the marginal layer. With the advancement of age, the ependymal layer diminishes in size, while the mantle and marginal layers increase in size forming the future grey and white matters, respectively.
