Paper, 'Preliminary note on the relation of the ungual corium to the periosteum of the ungual phalanx' by Frederick Augustus Dixey

Description

Dixey writes: 'The corium underlying the epithelium of the developing nail in the human embryo is at an early age distinguishable from the cutis vera of the remainder of the digit by its greater thickness and density. Opposite the groove across the dorsal surface of the digit, which represents the anterior border of the growing nail, the thick firm connective tissue layer constituting the ungual corium does not thin out or pass into the general corium; but, still preserving its original thickness, it sinks deeply into the substance of the digit, and traversing the loose subcutaneous tissue in the form of a well-defined curved band, with the convexity generally directed forwards, it reaches and becomes continuous with the periosteum surrounding the distal extremity of the ungual phalanx.'
