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.
Stickler syndrome are involved in the production of type II and type XI collagen. Collagens are complex molecules that provide structure and strength to connective tissue (the tissue that supports the body's joints and organs). Mutations in any of these genes disrupt the production, processing, or assembly of type II or type XI collagen. Defective collagen molecules or reduced amounts of collagen affect the development of bones and other connective tissues, leading to the characteristic features of Stickler syndrome. Other, as yet unknown, genes may also cause Stickler syndrome because not all individuals with the condition have mutations in one of the
