The carpal joint is a compound joint composed of:
The carpal joint is a compound joint composed of:
:The '''antebrachiocarpal joint''' between the [[Bones and Cartilages - Horse Anatomy|radius/ulna]]and the proximal [[Bones and Cartilages - Horse Anatomy|carpal bones]]
:The '''antebrachiocarpal joint''' between the [[Bones and Cartilages - Horse Anatomy|radius/ulna]] and the proximal [[Bones and Cartilages - Horse Anatomy|carpal bones]]
:The '''middle carpal joint''' between the two rows of [[Bones and Cartilages - Horse Anatomy|carpal bones]]
:The '''middle carpal joint''' between the two rows of [[Bones and Cartilages - Horse Anatomy|carpal bones]]
:The '''carpometacarpal joint''' between the distal [[Bones and Cartilages - Horse Anatomy|carpal bones]] and the proximal [[Bones and Cartilages - Horse Anatomy|metacarpals]]
:The '''carpometacarpal joint''' between the distal [[Bones and Cartilages - Horse Anatomy|carpal bones]] and the proximal [[Bones and Cartilages - Horse Anatomy|metacarpals]]
The joint is a synovial joint, comprising a common outer fibrous capsule and three inner synovial pouches, one for each joint. '''Collateral ligaments''' extend from the radius to the [[Bones and Cartilages - Horse Anatomy|metacarpal bones]] on the medial and lateral aspect of the carpus. The '''carpal canal''' houses both the superficial and deep digital flexor tendon within a common synovial sheath.
The joint is a synovial joint, comprising a common outer fibrous capsule and three inner synovial pouches, one for each joint. The fibrous joint capsule is strengthened by the '''extensor retinaculum''' on the dorsal aspect and the '''flexor retinaculum''' on the palmar aspect. The '''carpal canal''' houses both the superficial and deep digital flexor tendon within a common synovial sheath.
Ligaments supporting the carpus include:
*'''Long lateral collateral ligament''': Attaches to the lateral styloid process of the radius, then divides into a superficial branch and two deep branches. The superficial branch attaches on the lateral metacarpal (splint) and the two deep branches insert on the ulnar carpal and 4th carpal bones.
*'''Long medial collateral ligament''': Attaches to the medial styloid process of the radius then runs to insert on the medial metacarpal (splint) bone. A deep branch then detaches to insert on 2nd carpal bone.
*'''Short ligaments''': Join neighbouring carpal bones either within the same row, or in the adjacent row.
