* Movement - flexion and extension.
* Movement - flexion and extension.
* This joint is associated with a pair of sesamoid bones on the palmar surface. Between the sesamoids in a groove lies articular cartilage which articulates with the sagittal ridge of metacarpal III.
* The cow has a pair of fetlock joints involving the metacarpal bone, the two proximal phalanges and two pairs of sesamoid bones. These sesamoids articulate with the proximal palmar edge of the proximal phalanges
* The joint capsule runs between all bones in the joint and attaching to the articular cartilage of the sesamoids. It has an extensive pouch under the extensor tendon continuing a quarter the length up the cannon bone.

* '''Collateral ligaments''' - bind the the metacarpal bone to the proximal phalanx, with a deep branch attaching to the sesamoid bone.
