The development of the sweat and sebaceous glands in the skin of the one-humped camel (Camelus dromedarius).
The sweat gland primordium appeared as a solid bud from the ental side of the epithelial cords of the growing hair follicles in the CRL 36 cm-fetus from the primary hair follicles and in the CRL 64 cm-fetus from the secondary ones. In the CRL 68 cm-fetus the glands were tubular with a slight curving of their lower third, which became convoluted at the CRL 83 cm-stage. At the latter age, clear myoepithelial cells were observed in the secretory portion as also in the duct. The buds of the sebaceous glands could be observed in the CRL 45 cm-fetus from the primary hair follicles and in the CRL 68 cm-fetus from the secondary ones. At the CRL 83 cm-fetal stage, the branched glands were elongated in shape and opened into the follicles by two separated ducts, united at the hair canal. The glands were in function nearly from its early development.
