The femur, or thigh bone, is the longest, strongest and largest bone (in terms of volume) in the human body. In fact, the femur bone is stronger than concrete. The word femur comes from the Latin word for thigh. The femur bone forms a part of the hip and a part of the knee, apart from the thigh. Its Latin genitives are femoris (in medical Latin) and feminis (in classical or literary Latin). These genitives are often incorrectly confused with the case forms for femina, which is the Latin word for woman.
The femur bone comprises a head, a neck, a greater trochanter and a lesser trochanter at the proximal end, a diaphysis or a shaft, and the medial and lateral condyles at the distal end. The body of a femur bone, which lies between the proximal end and the distal end, comprises a posterior corresponding to the linea aspera (the main structure of the diaphysis or shaft), the medial and the lateral. These are three borders which clearly demarcate the anterior, posteromedial and posterolateral surfaces. The gluteal tuberosity is attached to the gluteus maximus at the posterior. Beneath this rough surface is the linea aspera, which runs down the back end of the femur bones and attaches itself to the biceps femoris muscle.
