* Movement - extension, slight flexion.
* Movement - extension, slight flexion.
* The '''navicular bursa''' lies between the navicular bone and the deep flexor tendon.
* A distal sesamoid is closely associated with the distal phalanx, which has a navicular bursa present like in the horse.
* The joint capsule attaches to the articular periphery. There is a dorsal recess under the extensor tendons and a palmar one that runs to about half the height of the middle phalanx. It is dips between the distal phalanx and sesamoid and bulges laterally where it is related to the collateral ligaments.
* The joint capsule attaches to the articular periphery. There is a dorsal recess under the extensor tendons and a palmar one that runs to about half the height of the middle phalanx.
* '''Collateral ligaments''' - connect the distal part of the middle phalanx to the sides of the proximal distal phalanx.
* '''Collateral ligaments''' - connect the distal part of the middle phalanx to the sides of the proximal distal phalanx.
* '''Distal sesamoid ligaments'''' - connect the distal border of the navicular bone to the flexor surface of the distal phalanx.
* '''Dorsal ligament''' - yellow elastic tissue connecting the proximal dorsal border of the middle phalanx to the extensor process of the distal phalanx.
* '''Collateral sesamoid ligaments''' - fibroelastic ligaments that attach to the proximal phalanx with the collateral ligaments of the pastern joint and insert to the proximal border of the navicular bone.
* '''Distal sesamoid ligaments'''' - connect the distal border of the distal sesamoid bone to the flexor surface of the distal phalanx and has axial and abaxial parts.
* The ungual/lateral cartilages have a series of ligaments going to the medial/lateral surfaces of the three phalanges and distal sesamoid. There is also a fibrous band connecting the inner surfaces of the cartilages by crossing the superficial aspect of the deep digital flexor tendon.
* '''Collateral sesamoid ligaments''' - fibroelastic ligaments that attach the middle phalanx to the proximal border of the navicular bone.
* '''Distal interdigital ligaments'''- cruciate ligaments that attach the abaxial aspect of the proximal end of the middle phalanx to the axial surface of the opposing distal phalanx and distal sesamoid.
