What are the movements allowed by the ankle joint?

The ankle joint is a synovial joint between the lower end of the tibia, the articular surfaces of the medial and lateral malleoli, and the talus.
The joint is reinforced by several ligaments such as the medial and lateral ligaments and the anterior and posterior ligaments.
The movements allowed by this joint are flexion (dorsiflexion of the foot) and extension (plantar flexion of the foot).
