Ligaments. These are strong tissues that connect your bones to one another.Your skeletal system functions as a structural lattice that the rest of your body is built around and depends on for support.īesides bones, other parts of your skeletal system include: Your bones join together to make your skeleton: the structure that your entire body is built around - part of your musculoskeletal system. Examples of these minerals include calcium, phosphorus, and vitamin D. Then, your bones will release the minerals when your body needs them. Bones can also store necessary minerals when their levels are too high in your blood. Storing and releasing fat. Certain types of bones store fat and then release it when your body needs energy.Platelets help your blood clot, red blood cells deliver oxygen to your organs, and white blood cells help fight off infections. Producing your blood cells. Certain types of bones make your platelets, red blood cells, and white blood cells. These cells are made inside of your bones.For example, your ribs protect your heart and lungs, and your skull protects your brain. Protecting your internal organs. Your bones keep your organs safe from hard impacts, punctures, and other forms of injury.You also need to be able to coordinate your bones and shift your weight around them in order to move. Supporting your body and helping you move. Your bones literally hold up your body and keep it from collapsing to the ground.Your bones serve five main functions in your body, including: A normal adult has around 206 bones in their body. They’re lightweight structures that are incredibly strong. This causes the ligaments of the outside regions of the ankle to be stressed or torn again, resulting in increased pain, swelling, and/or tenderness.Bones are a key part of your skeletal system. This injury typically occurs when the foot is fixed against an object and is thrown into the inverted position. A fracture usually occurs in severe circumstances where the bottom of the Fibula (outside region of the ankle) is separated or broken. This fall stretches some of the ligaments located along the outside region of the ankle, which usually results in increased pain, swelling, and tenderness.Īnother injury that can occur to the ankle is called a fracture. A typical ankle sprain occurs when a patient steps onto an uneven surface and falls, causing injury to the supportive ligaments of the ankle. This causes instability of the ankle joint. Along the outside regions of the ankle, the supporting ligaments can become stretched or torn (partially or completely). Injuries to the ankle joint is one of the most common in the body. The inside region of the ankle is the medial malleolus. This bone is specifically the bottom, outside portion of the Fibula. The bone that sticks out along the outside of the ankle is the lateral malleolus. What is the Bone that sticks out on the side of your Ankle? They contribute to your ability to walk, push off, and/or pivot to change directions. These work together to allow for movement of the ankle and ankle. Many bones come together to form the various joints of the ankle/foot complex. The 2 cuneiform bones (lateral and middle) join the calcaneus to form the Calcaneocuboid joint. The two bones, the Cuboid, and Navicular bones, then join 3 smaller bones of the Cuneiform (lateral, middle, and medial). Similarly, the calcaneus joins the outer region of the foot at the Cuboid bone to form the Calcaneocuboid joint. Moving forward, towards the top and inside regions of the foot, the Talus joins together to form the Talonavicular joint at the Navicular bone. This region where the Talus and the Calcaneus come together creates the Subtalar joint. Along the bottom aspect of the Talus, this bone sits on the top of the Calcaneus or heel of the foot. These two bottom portions of the lower leg bones sit on top of the Talus, which form the tibiotalar joint. Involving about 7 major bones, the bones in the ankle are the bottom portions of the 2 lower leg bones the Tibia and Fibula. The ankle joint is located above the foot, where the lower leg and the top of the foot come together. By Bridget Bigale, PTA What are the 7 Bones in the Ankle?
