There are also two bony ridges connecting the two trochanters; the intertrochanteric line anteriorly and the trochanteric crest posteriorly. The depression in the temporal bone that articulates with the mandibular condyle. The information we provide is grounded on academic literature and peer-reviewed research. ATPase enzyme needed for muscle contraction is located in -. In other words, the lateral surface of the medial condyle (the medial wall of the intercondylar fossa) serves as the point of attachment for the posterior cruciate ligament; while the medial surface of the lateral condyle (the lateral wall of the intercondylar fossa) bears an indentation for the anterior cruciate ligament. The fibular collateral ligament (supporting structure that attaches the fibula to the femur) also has an insertion on the lateral condyle.

Get access to this video and our entire Q&A library, Bones of the Leg and Foot: Names, Anatomy & Functions. 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. The distribution of the weight of the organism is important in order to prevent trauma to supporting structures. When we make evaluative judgments we attempt to state not what is the case (as we do with descriptive claims), but rather, what should be the case and how the world can be better. Long-term symptoms after fracture include muscular weakness, limited standing and walking, gait abnormalities, some intermittent pain, and inability to return to preinjury work. Toward the middle of the shaft, there are three surfaces and three borders. spine or spinal cord is the weakest bone in human body. Fig 2 The posterior surface of the right femur. Patellofemoral articulation, along with the attached quadriceps and patellar tendons, forms the extensor mechanism of the knee. It is a rough area with numerous vascular foramina to accommodate traversing vessels. C. deltoid The lower limb contains 30 bones.
