The '''medial and lateral digital arteries''' run in the solar groove of the [[Phalanges - Horse Anatomy#Distal Phalanx|distal phalanx]]. Each gives off branches to the '''navicular plexus''' in the distal sesamoidean (impar) ligament. The navicular plexus gives rise to the '''distal navicular arteries''', which enter the [[Phalanges - Horse Anatomy#Distal Sesamoid (Navicular) Bone|distal sesamoid]] (navicular) bone at the distal border and anastamose within the foraminae of the bone. These distal navicular arteries supply the distal two thirds of the [[Phalanges - Horse Anatomy#Distal Sesamoid (Navicular) Bone|navicular bone]]. | The '''medial and lateral digital arteries''' run in the solar groove of the [[Phalanges - Horse Anatomy#Distal Phalanx|distal phalanx]].
