The cutis, derma, or true skin, is composed of a basis of dense fibrous structure, the fibres of which are closely interwoven one with another. Distributed through the meshes of the fibrous base of the skin are various glands and follicles. In the deeper-seated portions there are small masses of fatty tissue embedded in the fibrous net-work. At the superior part of the true skin exists what is called the papillated layer of the derma, so termed from the small papillae which everywhere stud its surface. It consists of vascular and nervous elements. The bloodvessels here are arranged in the form of capillary loops; the terminal branches of nerves wind round minute prolongations of tissue in which the sense of touch exists, and which are consequently termed tactile papillae, or tactile corpuscles (fig. 259).
