English: This diagram shows the anatomy of the ball and socket joint found in the hip. A ball and socket joint is a type of synovial joint in which the round surface of one bone fits into a round depression of another bone. 1.) The femur 2.) Femoral neck 3.) Femoral head 4) Acetabulum 5.) Acetabular Labrum 6.) Pelvis.
3D model of human hip bone. The ischium forms the lower and back part of the hip bone and is located below the ilium and behind the pubis. The ischium is the strongest of the three regions that form the hip bone. It is divisible into three portions: the body, the superior ramus, and the inferior ramus. The body forms approximately one-third of ...
In vertebrate anatomy, the hip, or coxa [1] (pl.: coxae) in medical terminology, refers to either an anatomical region or a joint on the outer (lateral) side of the pelvis.. The hip region is located lateral and anterior to the gluteal region, inferior to the iliac crest, and lateral to the obturator foramen, with muscle tendons and soft tissues overlying the greater trochanter of the femur. [2]
The gluteal muscles include the gluteus maximus, gluteus medius, gluteus minimus, and tensor fasciae latae.They cover the lateral surface of the ilium.The gluteus maximus, which forms most of the muscle of the buttocks, originates primarily on the ilium and sacrum and inserts on the gluteal tuberosity of the femur as well as the iliotibial tract, a tract of strong fibrous tissue that runs ...
The superior border is free; it is thick and irregular, and marked near the center by an impression for the insertion of the piriformis.. The inferior border corresponds to the line of junction of the base of the trochanter with the lateral surface of the body; it is marked by a rough, prominent, slightly curved ridge, which gives origin to the upper part of the vastus lateralis.
The external obturator muscle acts as a lateral rotator of the hip joint. As a short muscle around the hip joint, it stabilizes the hip joint as a postural muscle. [6] It also helps to abduct the hip joint when in flexion. [7] And it helps to stabilise the head of the femur in the socket during flexion and internal rotation as it's posterior ...

As the hip flexes, the tension in the ligament is reduced and the amount of possible rotations in the hip joint is increased, which permits the pelvis to tilt backwards into its sitting angle. Lateral rotation and adduction in the hip joint is controlled by the strong transversal part, while the descending part limits medial rotation. [4]
