| Abstract | ||||
| The histomorphological changes in the foetal sole of one-humped camel ranging from 8 to 125 cm CVR length was studied. In foetuses of 8 cm CVR length, the epidermis was composed of 2-3 cell layers. At 37 cm CVR length, the primary elements of stratum corneum appeared and rep laced the periderm. The anlagen of stratum lucidum was observed at 85 cm CVR length. The epidermis was well differentiated into 5 distinctive layers in full term foetuses (115-125 cm CVR length). The primordia of tubular glands appeared at 18 cm CVR length. These glands increased in depth and width throughout the intrauterine life. They could be disting uished into a presumptive duct and an end-piece at 45 to 60 cm CVR length. At 68 cm CVR length, the ducts were canlized and lined by two layers of epithelium. The end-pieces appeared as tubular structures, lined by 2 types of cells; inner cuboidal and outer elongated, in full term foetuses (115-125 cm CVR length). | ||||
