Coronary border
Margo coronalis
Definition
The coronary border of the distal phalanx is the proximal border that separates the articular surface from the parietal surface.
In carnivores, on the coronary border is the ungual crest that is shelf covering the root of the claw (separated from it at the base by the ungual groove).
In horses, the coronary border forms a central eminence called the extensor process for attachment of common digital extensor tendon.
