Objectives/Interrogation: The human hand is an organ specialized for fine motion and sensation, hence the relatively large representation of it on brain homunculus. The pathway of sensation starts from information sent by mechanoreceptors in the hand. This study reports the topography of Pacinian corpuscle in the fingertips of human, as the critical apparatus.

Methods: Ten fingers from both hands of one fresh frozen cadaver were examined. Glabrous skin distal to the distal interphalangeal joint was harvested deep to the periosteum, including its fat and subcutaneous tissue. The fingertips were divided into 10 specimens, consisting of 5 distal parts and 5 proximal parts. Modified gold chloride stain was performed. Sectioned specimens were observed under light microscopy and the volume was measured. The density of the corpuscle in the radial and the ulnar sides of the fingers, in the proximal and the distal sides, and in the right and the left hand were compared.

Results and Conclusions: The Pacinian corpuscles were only observed in the subcutaneous tissue. There was no significant difference in terms of density between distal to proximal sides and right to left hand. Ulnar and radial sides showed statistically significant difference in the fingers except for the thumb.

The Pacinian corpuscle is present with different density depending on its locations on the human finger tips' pulp.
