Muscles of the hip Muscles of the hip In human anatomy, the muscles of the hip joint are those muscles that cause movement in the hip. Most modern anatomists define 17 of these muscles, although some additional muscles may sometimes be considered. These are often divided into four groups according to their orientation around the hip joint: the gluteal group, the lateral rotator group, the adductor group, and the iliopsoas group. The muscles of the hip consist of four main groups The gluteal muscles include the gluteus maximus, gluteus medius, gluteus minimus, and tensor fasciae latae. They cover the lateral surface of the ilium.
Collagen, type XI, alpha 2 Collagen, type XI, alpha 2 Collagen alpha-2(XI) chain is a protein that in humans is encoded by the "COL11A2" gene. The COL11A2 gene produces one component of this type of collagen, called the pro-alpha2(XI) chain. Type XI collagen adds structure and strength to the tissues that support the body's muscles, joints, organs and skin (the connective tissue). Type XI collagen is normally found in cartilage as well as the fluid that fills the eyeball, the inner ear, and the center portion of the discs between the vertebrae in the spine (nucleus pulposus). Type XI collagen also helps maintain the spacing
