The arterial supply to the digit and fetlock of the thoracic limb comes mainly from the '''median palmar artery'''. The median palmar artery divides in the distal fourth of the [[Limb Bones and Cartilages - Horse Anatomy#Metacarpals and Metatarsals|metacarpus]] between the[[Tendons - Horse Anatomy#Flexors|superficial and deep digital flexor tendons]] and the [[Tendons - Horse Anatomy#Flexors|suspensory ligament]], to become the '''medial and lateral digital arteries'''. Part of the '''deep palmar arch''' anastamoses with the '''lateral digital artery''' to form the '''superficial palmar arch''', which supplies the [[Joints and Ligaments - Horse Anatomy#Metacarpophalangeal (Fetlock) Joint|fetlock joint]]. | The arterial supply to the digit and fetlock of the thoracic limb comes mainly from the '''median palmar artery'''.
