The patella (kneecap) is the largest sesamoid bone of the body. Which bone does the femur articulate with at the proximal end? While several ossification centers (points of . The rounded, proximal end is the head of the femur, which articulates with the acetabulum of the hip bone to form the hip joint. The femur articulates proximally with the acetabulum of the pelvis forming the hip joint, and distally with the tibia and patella to form the knee joint. The posterior (Front part) foot is formed by the seven tarsal bones. Senior Content Specialist | Updated On - Oct 25, 2022. C. synchondrosis All rights reserved. The depth of each facet is minimally enhanced by incomplete, cartilaginous rings known as menisci (singular, meniscus). B. intervertebral C. clavicle The fibular collateral ligament (supporting structure that attaches the fibula to the femur) also has an insertion on the lateral condyle. The mechanism of injury is typically a high velocity from the distal end of the bone that is transmitted proximally. Copyright The ball of the hip joint is made by the femoral head while the socket is formed by the acetabulum. Where does the femur articulate with the femur? right and wrong, good and bad. Required fields are marked *. Fig 2 The posterior surface of the right femur. The problem arises if there is damage to the neck of the femur; this could compromise the blood supply to the femoral head and lead to avascular necrosis. Not only are there age-related differences in the angle of inclination, but there is also significant sexual dimorphism related to this anatomical feature as well. An electric .. is formed by the movement of electric charges from one place to another. The extracapsular ligaments supporting the knee are the two collateral ligaments (one on either side of the joint) and the patellar ligament (anteriorly). Keep in mind, however, that the term describes the shape of a bone, not its size. Lack of relaxation between successive stimuli in sustained muscle contraction is known as. Joints can be classified structurally as? Over time, the malalignment can result in the destruction of the joint surfaces and the progression of osteoarthritis.

A sesamoid bone is a type of short bone. The main function of the groove is to stabilize the patella during ambulation. At its proximal end, the spherical head of the femur articulates with the acetabulum ( hip socket) of the os coxa ( hip bone) to form the . An ideal angle between the inferior margin of the femoral neck and the medial surface of the femoral shaft should be between 120 and 130 degrees. E. sheath, the dense layer of connective tissue that surrounds the entire skeletal muscle is the This problem has been solved! The medial wall of the fossa is formed by the lateral surface of the medial condyle, while the lateral wall is formed by the medial surface of the lateral condyle. The projection at the inferior end of the greater sciatic notch is the ischial spine. Does not articulate with the knee The head of the femur will articulate with the acetabulum of the hip bone. This ligamentoriginates from the acetabular notch and accommodates the artery of the ligament of head of the femur. B. medial end of clavicle The bones that articulate with the tibia are the femur, fibula, and talus. The most lateral aspect (the part closest to the greater trochanter) is known as the base of the femoral neck or the basicervical portion of the neck is the widest part of the neck of the femur. D. immobilization of the joint The blood supply of the proximal femur is of particular medical interest because of its susceptibility to damage. The tibia is the larger, weight-bearing bone located on the medial side of the leg, and the . There is another albeit minimal blood supply arising from the obturator artery and traveling along the ligament of the head of the femur. acetabulum The hip bone is part of the axial skeleton. A femoral neck fracture associated with low-velocity injuries often occurs on a background of osteopenia (decreased bone density); which may either be age or diet related. Branches arising from the deep femoral artery (also known as profunda femoris) also anastomose with both circumflex femoral arteries, as well as the inferior gluteal artery to form the cruciate anastomosis. However, extreme variation of the angle of inclination could change this relationship and increase the amount of stress across the neck of the femur. A. sternocleidomastoid Our experts can answer your tough homework and study questions. B. lateral meniscus 5 Which of the following surface features occur on the ulna? As you can see, the femur can have a lot of anatomical landmarks. The femur or thigh bone is found in the upper leg and is the longest bone in the body. The femur (/ f i m r /; pl.

D. supporting ligaments What bones does the fibula articulate with? 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. This information is intended for medical education, and does not create any doctor-patient relationship, and should not be used as a substitute for professional diagnosis and treatment.
