Histochemical and ultrastructural observations of the skin in one humped camel (Camelus Dromedarius)‎

الملخص EN

The present study was carried out on fifty healthy camel skin , the samples were collected from Al-Zubair abattoir in Basrah, counting each of the skin of the back, neck, and muzzle .

The results of study was determined the histological and histochemical characterization (Glycogen and Lipids)and ultrastructural examined samples.

The histological structure of skin of all examined regions of the camel composed of the epidermis and dermis.

The epidermis layer was appeared different in thickness among the examined samples, depending on the site of sample, however, the epidermis was composed of four secondary layers contain stratum corneum, stratum granulosum, stratum spinosum and stratum basal layers, while the dermis composed of two nuclear non separated layers includes superficial papillary and reticular layers.

The histochemical study was referred to the presence of glycogen and lipid.

The glycogen granules were noticed inthe cells of the basal layer of the epidermis, which appeared as a dense granules in the dermis layer, also, the glycogen compound was found in blood vessels, smooth muscle which associated with the follicles and sweat gland ducts.

The lipid drops were shown in the dermis and epidermis layer, the lipid droplets found in graduate concentration toward the tissue lining cells
