The Organogenesis of Camel (Camelus dromedarius) Adrenal Gland and its Relation to the Mesonephros, Metanephros and Gonads Topography and Histogensis Study
Asian Journal of Research in Animal and Veterinary Sciences,
The aim of the present study are to investigate the topography and histology of the adrenal gland during the early stages of development. This study was conducted in 33 camel fetuses collected from different slaughter houses in Sudan, then standards anatomical and histological studied were used to analysis theses amples. The primordium of the adrenal gland appeared in the intermediate mesoderm lateral to the aorta at 2.8 cm CVRL(Crown Vertebral Rump Length) foetus (73 days of age). The neuroblasts migrated from the neural crest through the dorsal mesentery and were found inside the capsule and their migration reached the maximum at 22 cm CVRL foetus (126 days of age). The left adrenal gland was situated more caudal than the right adrenal gland. In conclusion, the cell of foetal zone was the first zone to be differentiated, the cells of zona fasiculata were formed as early as 7 cm CVRL foetus, then the cells of the zona glomerulosa were formed the medulla was larger than the cortex and the neuroblasts were began to be differentiated. The development of the camel foetal adrenal gland in general is similar to the development of the foetal adrenal glands of other domestic animals but with special features of its own.
- urogenital ridge
- coelomic epithelium
- adrenal gland
- neural crest
