The hydropathic encyclopedia : a system of hydropathy and hygiene in eight parts ..designed as a guide to families and students, and a text-book for physicians . ATOMY. The derma, or cutis (true skin), is chiefly composed of elastic eellulo-fibrous tissue,abundantly supplied with blood-vessels, lymphatics,and nerves. It is divided into a deep stratum, called corium, the struc-ture of which is dense, white, end coarse, forming a network of chan-nels, by which the branches of vessels and nerves pass to the super-ficial layer; and a superficial stratum, called papillary, which is raisedin the form of papilla?, or conical prominences, each being composedof a convoluted capillary vesse1 and a convoluted nervous loop. Fig. 107 Fig. i07 shows the anatomy of a portion of the skin taken from the palm of the hand. 1. Papillary layer,marked by longitudinal furrows (2), which arrange thepapillae into ridges, i. Transverse furrows, which dividethe ridges into small quadrangular clumps. 4. The retemucosum raisec from the papillary layer and turnedback. 5, 5. Perspiratory ducts drawn out straight by theseparation of the rete mucosum from the papillary INTEGUMENT OF THE HAND. The epiderma, or cuticle (scarf-skin), en-velops and protects tlie derma, of which it isa product. Its external surface is hard andhorny, its internal soft and cellular; this sur-face or layer is calletLthe 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 papilUe, but they are supposed to be interwoven withthe capillary and mucous plexuses in the superficial strata of the derma.
