Fig. 107 Fig. 1D7 Bhows the anatomy of a portion of the skin taken from the palm of the hand. 1. Papillary layer,marked hy longitudinal furrows (J), which arrange thepapillas into ridges. «. Transverse furrows, which dividethe ridges into small quadrangular clumps. 4. The retermicosum raisec trout the papillary layer and turnedback. 5, 5. Perspiratory ducts drawn out straight by theseparation of the rete mucosum from the papillary tVTEGUMENT OF THE HAND. The epiderma, or cuticle (scarf-skin), en-velops and protects the derma, of which it isa product. Its external surface is hard andhorny, its internal soft and cellular; this sur-face or layer is called the rete mucosum. Thewhole epidermal structure is laminated, theplates or scales increasing in density from the inner to the outersurface. The pores of the epiderma are the openings of the perspiratoryducts, hair follicles, and sebiparous glands. The arteries of the dermadivide into innumerable intermediate vessels, forming a capillary plexusin the superficial strata and papillary layer. No lymphatics have beendiscovered in the papillas, but they are supposed to be interwoven withthe capillary and mucous plexuses in the superficial strata of the derma. Appendages of the Skin.—These are the nails, hair, sebiparousglands, and perspiratory glands and ducts. The nails are a part of the epiderma,
