The femur, or thigh bone, is the longest, heaviest, and strongest bone in the whole human body. All of the body’s weight is sustained by the femurs during plenty of activities, such together running, jumping, walking, and standing. Extreme forces likewise act upon the femur thanks to the toughness of the muscle of the hip and thigh the act ~ above the femur to relocate the leg. The femur is classified structurally as a lengthy bone and is a significant component that the appendicular skeleton. Continue Scrolling come Read much more Below...

On that is proximal end, the femur creates a smooth, spherical procedure known as the head of the femur. The head that the femur forms the ball-and-socket i know well joint through the cup-shaped acetabulum the the coxal (hip) bone. The rounded form of the head permits the femur to relocate in virtually any direction in ~ the hip, consisting of circumduction and rotation approximately its axis. Simply distal native the head, the femur narrows considerably to form the neck the the femur. The neck that the femur extend laterally and also distally indigenous the head to provide extra room for the foot to relocate at the i know well joint, yet the thinness that the neck offers a an ar that is at risk to fractures.

At the finish of the neck, the femur turns around 45 degrees and also continues distally and slightly medially toward the knee as the human body of the femur. In ~ the peak of the body of the femur ~ above the lateral and posterior next is a large, unstable bony projection known as the better trochanter. Just medial and distal come the greater trochanter is a smaller projection recognized as the lesser trochanter. The greater and lesser trochanters serve as a muscle attachments sites for the tendons that many powerful muscles that the hip and also groin such together the iliopsoas group, gluteus medius, and also adductor longus. The trochanters also widen and also strengthen the femur in a an essential region the high stresses as result of external trauma and also the pressure of muscle contractions.

On the distal end, the femur forms the knee joint through the tibia the the lower leg. The distal finish of the body of the femur widens significantly above the knee to type the rounded, smooth medial and also lateral condyles. The medial and lateral condyles that the femur fulfill with the medial and lateral condyles the the tibia to type the articular surfaces of the knee joint. In between the condyles is a depression called the intercondylar fossa that provides an are for the anterior cruciate ligament (ACL) and also posterior cruciate ligament (PCL), i beg your pardon stabilize the knee follow me its anterior/posterior axis.
