Labeled ankle diagrams are available for your body part anatomy teaching or studying resources. These anatomy diagrams show the illustration of ankle structures in details. The true ankle joint is composed of three bones, seen above from a front, or anterior, view: the tibia which forms the inside, or medial, portion of the ankle; the fibula which forms the lateral, or outside portion of the ankle; and the talus underneath. The true ankle joint is responsible for the up-and-down motion of the foot. Take a look at the following ankle diagram.
The components of ankle are illustrated in the above ankle diagram. These components of the ankle, along with the muscles and tendons of the lower leg, work together to handle the stress your ankle endures as we walk, run, and jump. The various ligaments that surround the ankle together help form part of the joint capsule, a fluid-filled sac that surrounds and lubricates articulating joints. In the following joint diagrams, you’ll learn more about the muscle and ligaments of the ankle. The major ligaments of the ankle are: the anterior tibiofibular ligament, which connects the tibia to the fibula; the lateral collateral ligaments, which attach the fibula to the calcaneus and gives the ankle lateral stability; and, on the medial side of the ankle, the deltoid ligaments, which connect the tibia to the talus and calcaneus and provide medial stability.
There are also multiple muscles in the ankle: The peroneal muscles (peroneus longus and peroneus brevis), on the outside edge of the ankle and foot. These muscles allow the ankle to bend downward and outward. The calf muscles (gastrocnemius and soleus), which are connected to the calcaneus via the Achilles tendon. The tightening and relaxing of the calf muscles enables the ankle to bend downward and upward. The posterior tibialis muscle, which supports the arch of the foot and enables the foot to turn inward. The anterior tibialis muscle, which enables the ankle and foot to turn upward.
