The tibia is shaped like a long, straight stick. It has a thick top part called the "tibial plateau" that connects to the knee. This part has smooth surfaces that help with movement. Below the plateau is the "body" of the tibia, which is long and narrow. At the bottom, the tibia gets wider and forms a lump called the "medial malleolus," which you can feel on the inside of your ankle. The tibia is covered by a tough layer called "periosteum," and inside, it has bone marrow, where blood cells are made! 🩸
