What is the structure and function of the femur?

The femur is the longest, heaviest, and strongest bone in the human body. The main function of the femur is weight bearing and stability of gait. An essential component of the lower kinetic chain. The upper body’s weight sits on the 2 femoral heads. brainlab.orgИзображение:brainlab.orgThe femur is the primary bone of the leg. It supports the weight of the body on the leg and is capable of carrying 30 times the weight of the body. The femur provides the ability for articulation and leverage for the leg. Articulation allows for standing, walking, and running. The top of the femur bone, or thighbone, is called the femoral head. The femoral head is nearly spherical, smooth, and sheathed by cartilage. This cartilage helps protect the femur and pelvis during movement of the hip joint.The femur is an important bone in the leg and is critical to how the body moves at the hip. Even though it is the strongest bone in the body, it is not immune to injury. Femoral fractures hip dislocations and other conditions can be very serious if left untreated and can have a long-term impact on movement.As femur is a long bone, it has two ends: proximal and distal. The end, which lies on the side of the hip, is called proximal femur, and another on the side of knee is referred to as distal femur. The region between these two ends is called the shaft.



What is the structure of the femur?

femur, also called thighbone, upper bone of the leg or hind leg. The head forms a ball-and-socket joint with the hip (at the acetabulum), being held in place by a ligament (ligamentum teres femoris) within the socket and by strong surrounding ligaments.

How does the structure of the femur relate to its function?

The femur is the longest bone in the human skeleton. It functions in supporting the weight of the body and allowing motion of the leg. The femur articulates proximally with the acetabulum of the pelvis forming the hip joint, and distally with the tibia and patella to form the knee joint.

What is the name of the structure in which the head of the femur sits?

The acetabulum is the cup-shaped socket on the lateral aspect of the pelvis, which articulates with the head of the femur to form the hip joint.

What is the function of the head of the femur bone?

The head articulates with the acetabulum of the pelvic bone and forms the hip, while the greater trochanter serves as a site for muscles to attach. The shaft of the femur transfers the stress load from the hip joint to the knee, and is generally thick and round in cross section.

Why is the femur important to the hip?

The femur is also the place of attachment for many muscles and ligaments. … The femur is attached to the hip via a ball and socket joint, providing movement and a source to articulate the pelvis.

What is the proximal end of the femur bone?

The proximal end includes the femoral head, neck, and greater and lesser trochanters. The head articulates with the acetabulum of the pelvic bone and forms the hip, while the greater trochanter serves as a site for muscles to attach.
