Types of Joints
In human body, joint is a junction that connects bones and cartilage together. Joints help in movement of the body like running, walking, and shaking hands. Force generated by muscle is used for carrying out movements through various joints. Joints are classified into different types on the basis of motion, structure, and function.

The joint also acts as a shock absorber as the heel strikes the ground during the first phases of gait. Key facts about the ankle joint. Type.
What are the ligaments in the ankle?
The lateral collateral ligament is a strong compound ligament that reinforces the lateral aspect of the ankle joint. It is comprised of three distinct bands: 1 Anterior talofibular ligament: a weak, flat band that originates on the lateral malleolus of the fibula and extends anteromedially to the lateral side of the neck of the talus. 2 Posterior talofibular ligament: a strong band that extends medially and posteriorly from the distal part of the lateral malleolar fossa of the fibula to the lateral tubercle of the talus. It is also connected to the medial malleolus by a tibial slip of fibres. 3 Calcaneofibular ligament: a long band that originates from the apex of the lateral malleolus of the fibula, and extends posteroinferiorly to attach on a tubercle on the lateral aspect of the calcaneus.
What is a tibia and fibula joint?
It is a complex hinge joint composed of two articulations. It is often described as a tenon and mortise joint, as the tibia and fibula act as a mortise and form a notch in which the body of the talus fits, acting as the tenon.

The articulation between the tibia and the talus bears more weight than ...
What is the ankle?
Anatomical terminology. The ankle, or the talocrural region, is the region where the foot and the leg meet. The ankle includes three joints: the ankle joint proper or talocrural joint, the subtalar joint, and the inferior tibiofibular joint. The movements produced at this joint are dorsiflexion and plantarflexion of the foot.
What is the only mortise and tenon joint in the human body?
Ankle joint. The talocrural joint is the only mortise and tenon joint in the human body, the term likening the skeletal structure to the woodworking joint of the same name. The bony architecture of the ankle consists of three bones: the tibia, the fibula, and the talus.
Which joint is most commonly injured?
Of all major joints, the ankle is the most commonly injured. If the outside surface of the foot is twisted under the leg during weight bearing, the lateral ligament, especially the anterior talofibular portion, is subject to tearing (a sprain) as it is weaker than the medial ligament and it resists inward rotation of the talocrural joint.
What are the ligaments in the ankle joint?
Ligaments. The ankle joint is bound by the strong deltoid ligament and three lateral ligaments: the anterior talofibular ligament, the posterior talofibular ligament, and the calcaneofibular ligament .
What connective tissue is located between the ankle and the foot?
A number of tendons pass through the ankle region. Bands of connective tissue called retinacula (singular: retinaculum) allow the tendons to exert force across the angle between the leg and foot without lifting away from the angle, a process called bowstringing. The superior extensor retinaculum of foot extends between the anterior (forward) surfaces of the tibia and fibula near their lower (distal) ends. It contains the anterior tibial artery and vein and the tendons of the tibialis anterior muscle within its tendon sheath and the unsheathed tendons of extensor hallucis longus and extensor digitorum longus muscles. The deep peroneal nerve passes under the retinaculum while the superficial peroneal nerve is outside of it. The inferior extensor retinaculum of foot is a Y-shaped structure. Its lateral attachment is on the calcaneus, and the band travels towards the anterior tibia where it is attached and blends with the superior extensor retinaculum. Along with that course, the band divides and another segment attaches to the plantar aponeurosis. The tendons which pass through the superior extensor retinaculum are all sheathed along their paths through the inferior extensor retinaculum and the tendon of the fibularis tertius muscle is also contained within the retinaculum.
