Structure is similar to that of the hand, with adaptations for supporting weight These situations are classified as mixed deformities. D. 9 The knee joint is a relatively unstable hinge joint formed by the interaction of three bones: femoral condyles articulate with the tibial plateau (tibiofemoral joint) and the patella (patellofemoral joint). These are the femur, patella, tibia, fibula, tarsal bones, metatarsal bones, and phalanges (see Chapter 8.1 Figure 8.2 ). D. pectoralis tibia.

These are (from cranial to caudal) the plantaris muscle, the lateral head of gastrocnemius, and the popliteus muscle. The femur or thigh bone is found in the upper leg and is the longest bone in the body. 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. The neck itself is anteverted (rotated laterally) at a variable angle between 10 15o (angle of torsion). And the leg is specifically located between the knee joint and the ankle joint. What bones are visible from the anterior view of the skull. While the cruciate and meniscofemoral ligaments provide support within the synovial joint capsule, more robust ligaments are situated outside the capsule to keep the bones in line. The distal end of the femur has a rich blood supply arising from the popliteal vessels and the deep perforators. Neck of femur fractures (NOFs) are increasingly common and tend to be sustained by the elderly population as a result of low energy falls in the presence of osteoporotic bone. It is the weight-bearing component of the knee joint. Does not articulate with the knee E. all of the above, The most common athletic knee injury is the damage to the The entire leg region comprises two joints, the knee joint, and the ankle joint.

There is another albeit minimal blood supply arising from the obturator artery and traveling along the ligament of the head of the femur. E. glenoid cavity, Which of the following surface features occur on the ulna? They also form some kinds of white blood cells. 2. The patella does not join with the tibia bone.

The Golden Rule is a classic example of a normative principle: We should do to others what we would want others to do to us. The femoral head articulates with the hip via the acetabulum; giving rise to the hip joint (femoroacetabular joint). As the name implies, an articulation is where two bone surfaces come together (articulus = "joint"). B. extensor digitorum longus C. coracoidal These cookies do not store any personal information.
