Explanation: 'joint' is the correct English translation for 'articulación'
The subastragalar joint contributes a considerable amount of lateral motion in the use of the foot.
The calcaneoastragaloscaphoid joint allows a twisting rotation to the foot. The astragalus is the fixed point and the anterior part of the foot is moved. In proration the head of the astragalus rolls inward and downward in the socket of the scaphoid.
The midtarsal joints have as their chief movements abduction and adduction of the anterior part of the foot.
The metatarsophalangeal joints contribute very little motion to the foot
