The lymph-vesselsproper are found for the most part accompanying the upper and lower sys-tems of blood-vessels. Nerves.âBoth medullated and non-medullated fibers are found in theskin, arising from nerve-bundles in the subcutaneous tissue, spreading outhorizontally to follow the blood-vessels in their upper and lower system, andbecoming finer as they ascend upward to the papillae. The nerve-fibers insome instances end in the Pacinian or Vaters corpuscles of the subcutaneoustissue, and in the tactile or Meissners corpuscles of the papilla?. According ANATOMY. 769 to Robinson, some of the medullated fibers lose their medullary sheath in thecorium and continue upward as non-medullated fibers, and some fibers before. .-Mm Fig. 225.âSection of skin of the palm of the hand, injected: , stratum corneum ; str I stratumlucidum; , papillary blood-vessels, injected; , rete Malpighii ; c, eorium. reaching the subpapillary region return to the lower part of the corium and then reascend to the papillae. The capillaries of the papillae are surrounded by a dense network of fine nerve-fibers with many nuclei.
