D. synotosis It is bordered medially and laterally by the corresponding supracondylar lines, and inferiorly by the superior border of the fibrous capsule of the knee. Forming a joint, termed as tibiofibular joint, and the lower end of the bone is projected beyond the end of tibia, forming the lateral malleolus. The head of the femur articulates with the acetabulum in the pelvic bone forming the hip joint, while the distal part of the femur articulates with the tibia (shinbone) and patella (kneecap), forming the knee joint?. This is a raised longitudinal impression that runs along the long axis of the femur. Although it is described as being a cylindrical structure, the shaft of the femur has several surfaces and borders that blend seamlessly. The caudal aspect of the surface forms part of the floor of the popliteal fossa. Ques. C. mechanical stress The knee joint consists of three compartments. Fibula. The head of the fibula joins with the lower end of femur bone and forms the tibiofibular joint. Distally, the linea aspera widens and forms the floor of thepopliteal fossa, the medial and lateral borders form the medial and lateral supracondylar lines. They contribute to an anastomotic ring around the femoral neck. Is Costco a good place to buy patio furniture? Attached to the free edges of the acetabular labrum.
