The hip flexors can be found connecting the top of the femur, which is the largest bone in the body, to the lower back, hips, and groin. This ball-and-socket joint -- the body's largest -- fits together in a way that allows for fluid movement. The femur is the upper leg bone or thigh. The articular cartilage is kept slick by fluid made in the synovial membrane (joint lining). The hip muscles encompass many muscles of the hip and thigh whose main function is to act on the thigh at the hip joint and stabilize the pelvis.Without them, walking would be impossible. This anatomical atlas was especially designed for a specific public (radiologists, surgeons, rheumatologists and physicians specializing in musculoskeletal imaging). 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.

Michael Menna, DO, is a board-certified, active attending emergency medicine physician at White Plains Hospital in White Plains, New York. Orthopaedics & Traumatology: Surgery & Research, 103(1), S161-S169. Loss of blood flow causes the head of the femur to stop and the bone tissue dies, known as osteonecrosis. At the end of this module, there are 3D reconstructions of the hip joint (hip bone and femur) as a review of musculoskeletal anatomy. Amphibians and reptiles have relatively weak pelvic girdles, and the femur extends horizontally. The femur is extremely hard and not easy to break. You will be required to label the fovea capitis, lateral epicondyle, linea aspera, intertrochanteric line, intertrochanteric crest, adductor tubercle, greater trochanter, lesser trochanter etc. Below the greater trochanter is the lesser trochanter, situated at the base of the neck of the femur. There are two other protrusions near the top of the femur, known as the greater and lesser trochanters. A cross section of the shaft in the middle is circular but flattened posteriorly at the proximal and distal aspects. Femur quiz for anatomy and physiology! The proximal part of the right femur. The hip joint is a ball-and-socket joint; the round head of the femur rests in a cavity (the acetabulum) that allows free rotation of the limb. Try again to score 100%. It has rounded edges on either side of the knee joint, known as the condyles. The femur is the longest and strongest bone in the body, and it takes a great deal of force to break it.

That thin strip of bone is femoral neck. This manifests clinically as a shortened and externally rotated lower limb. It has a circular head that looks like a mushroom ballooning out of one corner. It acts as the site of origin and attachment of many muscles and ligaments, and can be divided into three parts; proximal, shaft and distal. The greater trochanter attaches to tendons that connect to the gluteus minimus and the gluteus medius muscles. The bones together make up the hip. The ventral and dorsal aspect of the distal part of the right thigh bone. A human male adult femur is about 19 inches long and weighs a little more than 10 ounces. The femur is the only bone in the thigh and the longest bone in the body. These fractures often involve the cartilage surface of the knee joint and are most commonly seen in people with severe osteoporosis or those who have previously undergone total knee replacement surgery. The proximal end of the femur (the part closest to the heart) is the head of the femur. In primitive tetrapods, the main points of muscle attachment along the femur are the internal trochanter and third trochanter, and a ridge along the ventral surface of the femoral shaft referred to as the adductor crest. There are also two bony ridges connecting the two trochanters; the intertrochanteric line anteriorly and the trochanteric crest posteriorly. Synovial fluid is what allows us to flex our joints under great pressure without wear. STUDY. Created by.
