The shinbone, also known as the tibia, is one of the two long bones in the lower leg. It is located between the knee and the ankle, playing a crucial role in supporting the body's weight and facilitating movement. The tibia is larger and stronger than its counterpart, the fibula, which runs alongside it. The shinbone connects with the femur at the knee joint and the talus at the ankle joint. It is essential for activities such as walking, running, and jumping. Injuries to the tibia, such as fractures, can significantly impact mobility and require medical attention.
