Multiple Choice

Which vessels supply the coronary band with oxygenated blood?

Oxygenated blood to the coronary band comes from vessels that run around the edge of the hoof at the coronet—the coronal arteries. They form a ring around the coronary band and send branches into the tissue there, delivering the needed blood supply for the sensitive corneal region and supporting hoof growth. The dorsal arteries of the distal phalanx mainly supply the dorsal aspect of the distal phalanx and nearby structures, not the coronal band. The palmar arteries supply the palmar side of the limb and contribute to hoof perfusion but are not the primary source for the coronal band. Veins carry blood away from the area and don’t provide the oxygenated supply.
