E. acromial process and the manubrium, The clavicle articulates with the scapula The mechanism of injury is typically a high velocity from the distal end of the bone that is transmitted proximally. The tibia, or shin bone, spans the lower leg, articulating proximally with the femur and patella at the knee joint, and distally with the tarsal bones, to form the ankle joint. The femur begins to develop between the 5th to 6th gestational week by way of endochondral ossification (where a bone is formed using a cartilage-based foundation).

Femur anatomy is so unique that it makes the bone suitable for supporting the numerous muscular and ligamentous attachments within this region, in addition to maximally extending the limb during ambulation. It also serves as the anterior attachment of the hip joint capsule. The zygomatic bone articulates with the sphenoid bone, maxilla, frontal bone, and temporal bone to form the lateral wall of the floor of the orbit, part of.

The head of the fibula forms the proximal end and articulates with the underside of the lateral condyle of the tibia. However, extreme variation of the angle of inclination could change this relationship and increase the amount of stress across the neck of the femur. The pelvis features two cup-shaded depressions called the acetabulum, one on either side of the body. C. vertebra There are 30 bones present in total in the lower limbs of the human body. Anteriorly, the shaft is smooth and devoid of distinguishing features. D. protrusion of the nucleus pulposus Supports the knee joint posteriorly. Thefemuris the only bone in the thigh and the longest bone in the body. In addition, the fibula is not a weight-bearing structure (the tibia is the weight-bearing bone of the lower leg). Neurovascular structures at risk include the femoral nerve and artery. On the other hand, the anterior surface is flattened, located within the joint capsule, and meets the proximal end of the femoral shaft at the intertrochanteric line. As you can see, the femur can have a lot of anatomical landmarks. It will also discuss the blood supply of the femur and summarize the points of muscular and ligamentous attachment. What are the bones present in the foot? The femur is the single bone of the thigh. Please note that the mechanical axis of the femur differs from the anatomical axis of the femur (a line running from the center of the greater trochanter, along the femoral shaft, and ending at the center of the knee joint line). B. bacterial infection The caudal aspect of the surface forms part of the floor of the popliteal fossa. Foot. Next to the femoral neck, there are two protrusions known as greater and lesser trochanters which serve as sites of muscle attachment. We use cookies to improve your experience on our site and to show you relevant advertising.

The largest, longest, and strongest bone in the human body, it articulates with the os coxa at the hip and with the tibia at the knee. This triangular bone is suspended within the tendon of the rectus femoris muscle from above, and the patellar tendon arising from below. While the apex and anterior aspect of the lesser trochanter are course to touch, the bony projection is smooth elsewhere. The tibial plateau also serves as the point of attachment for the anterior and posterior cruciate ligaments that insert on the contralateral wall of the intercondylar fossa. The femur is the single bone of the thigh. E. transformation of fibrocartilage to hyalin, The knee joint is stabilized by _____ major ligaments? The talus (or ankle bone) is an irregularly shaped bone that links the foot and the leg through the ankle joint. It is associated with a crescent-shaped, rough, depression known as the trochanteric fossa, found on the medial surface of the apophysis. The femur is the single bone of the thigh. It also accounts for the characteristic inward bulging at the knees. (3 Marks). The femoral neck is about 5 cm long and can be subdivided into three regions.

It is bowed anteriorly, which contributes to the weight bearing capacity of the bone. D. manubrial The acetabulum is a cup-shaped groove that receives the head of the femur, and is formed by the fusion of the three pelvic bones: the ischium, ilium, and pubis. Surgery is often needed to fix a broken femur. This manifests clinically as a shortened and externally rotated lower limb. These retinacular arteries eventually form their own intracapsular anastomosis within the capsule. The extracapsular fractures are also called basicervical fractures, while intracapsular fractures are transcervical and subcapital. D. navicular There are also two bony ridges connecting the two trochanters . D. femur, At the end of each muscle, the collagen fibers form a? Lower Extremity: Femur, Patella, Tibia.
