The femurs are located in the upper part of the human body, specifically in the thighs. They are the longest and strongest bones in the human skeleton, extending from the hip joint to the knee joint. Each person has two femurs, one in each leg, playing a crucial role in supporting body weight, facilitating movement, and providing structure. The femur connects with the hip socket at the proximal end, allowing for a wide range of motion at the hip. At the distal end, it articulates with the tibia and patella at the knee, enabling movement during walking, running, and jumping.
