Nov 13, 2020 · The femur is the only bone in the thigh and the longest bone in the body. It acts as the site of origin and attachment of many muscles and ligaments, and can be divided into three parts; proximal, shaft and distal.

Sep 11, 2023 · Proximally, the femur articulates with the pelvic bone. Distally, it interacts with the patella and the proximal aspect of the tibia. The femur begins to develop between the 5th to 6th gestational week by way of endochondral ossification (where a bone is formed using a cartilage-based foundation).

Nov 8, 2021 · The femur is a long bone with two ends: proximal and distal. The end, which lies on the side of the hip, is called the proximal femur, and another on the side of the knee is referred to as the distal femur.

The upper (proximal) end of your femur connects to your hip joint. The proximal end (aspect) contains the: Head. Neck. Greater trochanter. Lesser trochanter. Intertrochanteric line and crest. The shaft is the long portion of the femur that supports your weight and forms the structure of your thigh. It angles slightly toward the center of your body.

Aug 11, 2024 · The only bone in the upper leg, the femur is divided into three parts: proximal, shaft, and distal. Proximal end: This part of the femur includes the femoral head , the ball part of the ball-and-socket hip joint, the neck , and the greater trochanter .

Nov 17, 2023 · The innervation of the periosteum of the femur is derived proximally from the nerves that supply the hip joint (femoral and obturator nerves). The distal periosteum is supplied by the nerves that innervate the knee (common fibular, femoral, obturator, and tibial nerves).

2 days ago · Proximal End Head of the Femur. Shape and Position: Spherical in shape and forms the proximal-most part of the femur.; Articulations: Fits into the acetabulum of the hip bone to form the hip joint.; Notable Features: . The fovea capitis: A small depression on the head where the ligament of the head of the femur attaches.; Neck of the Femur. Shape and Orientation: Cylindrical and connects the ...

The femur acts as the site of origin and attachment of many muscles and ligaments, and can be divided into three parts; proximal, shaft and distal. [2] Proximal Femur: C omposed of the head, neck, greater trochanter and lesser trochanter.

Jun 9, 2024 · In animals with four legs, it is the upper bone in the back leg. The femur anatomy has several parts: the shaft, head, neck, and more. The top part fits into your hip joint, and the bottom connects to your shinbone (tibia) and kneecap (patella) to form your knee.

Proximally, the femur exhibits four key regions. The femoral head projects medially and superiorly and articulates with the acetabulum of the pelvis to form the hip joint. Immediately lateral to the head is the neck that connects the head with the shaft. It is narrower than the head to permit a greater range of movement at the hip joint.
