The articulation of bones means the joining together of two bones to form a joint. The patella is the kneecap and articulates with the distal femur. Where the femur articulates with the tibia, the bones form the knee joint. It is associated with a crescent-shaped, rough, depression known as the trochanteric fossa, found on the medial surface of the apophysis. D. manubrial Open fractures need to be cleaned and treated right away, since they come with a high risk of infection or other complications. 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). Patients may provide a history of trauma and associated pain from the injury. Patellofemoral articulation, along with the attached quadriceps and patellar tendons, forms the extensor mechanism of the knee. It is known as the groove for popliteus.

It functions as the point of insertion for the superior and inferior bands of the iliofemoral ligament which is attached to the tubercle proximally and distally respectively. 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 pelvic girdle is formed by a single hip bone. Our experts can answer your tough homework and study questions. The tendons of sartorius and gracilis muscles also pass over (but have no attachments) to the medial condyle of the femur. Below the ankle is the foot. Forming a joint, termed as tibiofibular joint, and the lower end of the bone is projected beyond the end of tibia, forming the lateral malleolus. The interaction of these three bones requires numerous ligaments to prevent disarticulation (separation of the bones that interact at their joint).

C. sacrum copyright 2003-2023 Homework.Study.com. The femur is the longest bone in the human skeleton. Ans. Ethical claims are not simply descriptive claims about the world. The intertrochanteric line starts anteriorly on a tubercle on the apex of the greater trochanter, near the intersection between the shaft and neck of the femur. Save my name, email, and website in this browser for the next time I comment. Integrates with the joint capsule. Note that the wording of the dictionary definition may vary from the wording below. 3 Introduction.
