Human anatomy, including structure and development and practical considerations . he inner surface of the prepuce and the glanspenis. They are especially numerous in the palms and soles, in the former localitynumbering more than iioo to the square centimetre (Horschelmann), and fewest onthe back and buttocks, where their number is reduced to about 60 to the squarecentimetre ; their usual quota for the same area is between two and three hundred. Modified simple tubular in type, each gland consists of two chief divisions, thebody (corpus) or gland-coil, the tortuously wound tube in which secretion takesplace, and the excretory duct (ductus sudoriferus) which opens on the surface of theskin, exceptionally into a hair-follicle, by a minute orifice, the szceat pore (pomssudorifenis), often distinguishable with the unaided eye. The body of the gland, irregularly spherical or flattened in form and yellowishred in color, consists of the windings of a single, or rarely branched, tube and com-monly occupies the deeper part of the corium, but sometimes, as in the palm and Fig. Cells from alveoli of sebaceous eland,showing reticulated protoplasm due topresence of oil droplets.
