Comparative Scanning Electron Microscopic study on the dorsal surface of the hand between two mammalian species and the human

The research is concerned with the comparative study of an important organ of the body of the living organism which called the skin between two types of mammals, namely the Baboon (Papio hamadryas) and Squirrel (Tamias striatus) on one hand, and human on the other. The study was based on the dorsal electron description of the skin and the identification and to compare the composition structures of the skin surface of the hair of the medium density to the densest in the monkey and squirrel, as well as the dead cells surrounding the hair in both the human and the monkey and the squirrel. The structures that have also been identified are the simple corneal layer in the cornea as well as the highly corneal and permeated by the pores of the sweat pore characteristic of the baboon and squirrel. The comparison and description, specifically for the skin of the apparent hand, is an input to the knowledge of similarities and differences between humans and those
