Distribution of human Pacinian corpuscles in the hand. A cadaver study.
The subcutaneous distribution and number of Pacinian corpuscles were studied in ten fresh cadaver hands. They were found to cluster close to nerves and vessels at the metacarpophalangeal joints and the proximal phalanx. The total mean number in the hand was 300 (192-424). The percentage of the total was 44 to 60% in the fingers, 23 to 48% in the metacarpophalangeal area and 8 to 18% in the thenar and hypothenar regions. Corpuscles in palmar skin overlying the distal phalanx were smaller than receptors in the metacarpophalangeal area. The lowest density of corpuscles was along the nerves and vessels of the middle phalanx.
