Section of skin showing two papillae and deeper layers of epidermis. The papillae contain blood vessels as well as the termination of nerve fibers in the shape of little bodies called tactile corpuscles. The papillae seem chiefly to exist for the purpose of giving the skin its sense of touch. Labels: a, vascular papilla, with capillary loop passing from subjacent vessel, c; b, nerve-papilla, containing tactile corpuscle, t; d, nerve passing up to tactile body; f, f, section of spirally winding nerve fibers.

A Pacinian Corpuscle, one of the organs of touch in the skin, which is composed of lamellae (3), consisting of connective tissue fibers, arranged concentrically around a central clear space (m), in which the nerve fiber (n) terminates at the distal extremity in a rounded end (a), which is often bifid or even trifid. They are found chiefly on the nerves of the palm of the hand and sole of the foot, the ends of the fingers, and the genital organs, lying in the subcutaneous tissue.
