What arteries supply the frog coria?

The frog’s corium is supplied mainly by branches of the palmar digital arteries that run along the palmar (inner) side of the digit and give off perforating branches into the frog tissue. This vascular path brings blood directly to the frog’s delicate corium, supporting its health and function under load. For comparison, the dorsal arteries of the distal phalanx feed the dorsal surface of the distal phalanx itself rather than the frog tissue. The coronal arteries supply the coronary band around the top edge of the hoof, not the frog interior. The bulbar arteries supply the frog’s bulb region and nearby structures, but the primary source for the frog corium is the palmar digital (palmar) arteries.
