Human anatomy, including structure and development and practical considerations . Wu Portion of corium from palmarsurface of hand after removal of epi-dermis ; each range inchides a doublerow of papillse, which imderlie thesuperficial cutaneous ridges and en-close openings of sweat glands; latterappear as dark points along rangesof papillfe. X Small portion of ]ireceilini, specimen,showing papilla; under higher magnifica-tion ; orifices of torn sweat glands are seenbetween papillse. X 24. ties and with small irregular meshes on the face (Blaschko). The best developedpapillae are on the flexor surfaces of the hands and feet, where they attain a heightof .2 mm. or more and are disposed in the closely set double rows that underlie thecutaneous ridges on the palms and soles above noted. The papillae afford fa\orablepositions for the lodgement of the terminal capillary loops and the special organs oftouch and are accordingly grouped as vascular and tactile. In recognition of the elevations, which in vertical sections of the skin appearas isolated projections, the corium is subdivided into an outer papillary stratum(corpus papillare), containing the papillae, and a deeper reticular stratum (tunicapropria), composed of the closely interlacing bundles of fibrous and elastic tissuethat are continued into the more robust and loosely
