A low power view of a sagittal section through a finger in the region of the distal interphalangeal joint. Note how the skin (S) on the palmar side is intimately associated with a thick region of dense fascia (DF) that anchors it in position and stops it sliding in the interests of a firm grip. At a deeper level, the bundles of fascial fibres (arrows) are mixed with fat, to form a pressure-tolerant, fibro-adipose tissue (FT). DP, distal phalanx; IP, intermediate phalanx.
