From which arteries do the frog coria receive arterial supply?

• A. Dorsal arteries of the distal phalanx
• B. Coronal arteries
• C. Bulbar arteries
• D. Palmar arteries

Answer: (D)

Arterial supply to the frog tissue comes from the palmar arteries, specifically the branches that become the palmar digital arteries and their perforating branches into the frog’s central tissue and digital cushion. These vessels run along the sides of the digit and reach up into the frog, delivering blood where it’s needed for the soft, resilient tissue.

Dorsal arteries of the distal phalanx mainly feed the dorsal surface and nearby hoof structures, not the frog itself. Coronal arteries serve the coronary band around the top of the hoof. Bulbar arteries are involved with the eye’s blood supply. So the palmar arteries are the primary source feeding the frog.
