| Abstract | ||
| The study aimes to described the histological stricture of skin in guinea pig an differention between thick and thin skin of different body regions , utilizing of (10) cutaneous specimens were taking from (6)anatomical regions including most of body which are abdomen , back, nose , ear , palmer pad and plantar pad. As the results revealed that the epidermis was thin in (ear ,abdomen and back) it composed of four secondary layers including from lower to upper: stratum Basale, Stratum Spinosum, Stratum Granulosum, and Stratum Corneum, while it was thick epidermis in nose, plantar pad , the palmer pad ,which characterized by presence of Stratum Lucidum beside the previous four layers. The study revealed a marked variation in the thickness of epidermis of the different skin regions: the thickest epidermis was in plantar pad (43.2) µm, on the contrary, the epidermis of ear region was found to be the thinnest 31.6 µm.it was also observed a direct relation between the whole thickness of the epidermis and the thickness of the Stratum corneum in all of the studied skin regions. Also we notice that the dermis composed of two essential layers. The superficial thin papillary layer which is located directly under the basement membrane and it's formed of loose and relatively cellular connective tissue and it included dermal papillae which is formed because the waves of basement membrane in different degree in anatomical regions and deep thick reticular layer which consists thick collagen fibers bundles that run parallel to the skin surface. The highest thickness of the dermis was observed in the plantar pad (36) µm, while it is reduced in the abdomen skin to (4) µm, the thickness of the other regions ranging between those two extremes .The study also clear the presence of carbohydrates in dermis more than epidermis as well as the epidermis – dermal junction is delicate in thin skin while dens in thick skin. | ||
