It is reinforced along the anteroposterior axis by the linea aspera.
In humans, the efficiency of the abductor mechanism is increased by the high angle of this structure's neck, and its bicondylar angle is much higher than in apes. It is laterally rotated by the popliteus muscle, and the obturator externus inserts on this bone's trochanteric fossa. It is reinforced along the anteroposterior axis by the linea aspera. This bone's distal end has a high lateral lip where it articulates with the largest sesamoid bone in the human body, and connects to the cartilaginous medial and lateral menisci. Its head, which contains the fovea capitis, articulates with the lunate surface of the acetabulum. For 10 points, identify this bone which is connected by the anterior and posterior cruciate ligaments to the tibia, the longest bone in the body.
