These are the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges (see Figure 6.51). THE femur consists of the diaphysis, the proximal epiphysis that extends through a neck to a (spherical) head - which articulates it with the bone hip or bone coxal - and the distal epiphysis that divides into two condyles, which attach to the tibia and patella. Continuation of the tendon of the semimembranosus muscle. Therefore the head of the femur may slip off of the supporting neck, thus the term slipped capital femoral epiphysis (or slipped upper femoral epiphysis) was coined. E. sheath, the dense layer of connective tissue that surrounds the entire skeletal muscle is the These are (from cranial to caudal) the plantaris muscle, the lateral head of gastrocnemius, and the popliteus muscle. B. lateral meniscus Ques. Distally, the linea aspera widens and forms the floor of thepopliteal fossa, the medial and lateral borders form the medial and lateral supracondylar lines.

The groove is continuous with the lateral lip of the linea aspera. All three bones that form the hip bone contribute to creating the acetabulum. The largest, longest, and strongest bone in the human body, it articulates with the os coxa at the hip and with the tibia at the knee. A person of 1.80 m have a femur of approximately 50 cm. This axis can be identified by drawing a vertical line from the center of the femoral head to the center of a horizontal line across the tibial plateau (the center of the knee joint line). This feature contributes to the difference in gait between the two sexes. Boney, saddle-shaped structure on the superior surface of the body of the sphenoid .

Find out more about the anatomy of the hip and knee joints using the following study units: The patella articulates with the patellar surface of the distal femur. D. pectoralis Although it does not directly articulate, some argue that the patella could be classified as a bone that articulates with the tibia because the two are loosely connected by the patellar tendon. Lower Extremity: The Fibula and Foot. Fig 6 Posterior surface of the distal right femur. The femur or thigh bone is found in the upper leg and is the longest bone in the body. Long-term symptoms after fracture include muscular weakness, limited standing and walking, gait abnormalities, some intermittent pain, and inability to return to preinjury work. It is comprised of two bones: the thighbone or femur, and the pelvis, which is made up of three bones called ilium, ischium and pubis. The hip joint is the junction where the hip joins the leg to the trunk of the body. The flat popliteal surface lies between them. The ilium, ischium, and pubis are joined together where the femur articulates with them . The lateral condyle also has a shallow groove below the lateral epicondyle through which the popliteal tendon travels. While these factors have been identified, a precise cause underlying these observations has not been found. Please see the table below that summarizes the ligaments associated with each joint. The medial apophysis is smaller, more conical, and extends in the posteromedial plane. And the leg is specifically located between the knee joint and the ankle joint. ; Ankle joint - articulates with the talus . The leg: Tibia and fibula in anatomical position with parts labeled. The fibula is the smaller lateral bone in the lower leg . At the superior (proximal) end of the tibia, a pair of flattened condyles articulate with the rounded condyles at the distal end of the femur to form the knee joint or tibiofemoral joint. Figure 2: The sacroiliac joint. Each articulation contains the names of two bones (or sockets).For example, the hip joint is known as the acetabulofemoral joint since it is where the acetabulum ("acetabulo-") of a coxal bone articulates with the head of the femur ("-femoral").
