Includes material from the fields of geology, oceanography, meteorology and astronomy through which we examine the physical laws and natural processes that have helped to shape and change Earth and the universe around it.
Although technically not part of the thigh, the patella, or kneecap, is included in this region as well. Figure 9: Right femur, anterior and posterior views A. Femur Landmarks / Markings : ï· Head: Rounded region at the proximal end of the femur; articulates with the acetabulum of the os coxa.
There are three bones of the os coxae (hip bone) that come together to form the acetabulum. Contributing a little more than two-fifths of the structure is the ischium, which provides lower and side boundaries to the acetabulum. The ilium forms the upper boundary, providing a little less than two-fifths of the structure of the acetabulum. The rest is formed by the pubis, near the midline.
