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 collagens are triple helices, and the differences lie in the make-up of the alpha peptides created in step 2. Collagen has an unusual amino acid composition and sequence: Cortisol stimulates degradation of (skin) collagen into amino acids. Most collagen forms in a similar manner, but the following process is typical for type I: Vitamin C deficiency causes scurvy, a serious and painful disease in which defective collagen prevents the formation of strong connective tissue. Gums deteriorate and bleed, with loss of teeth; skin discolors, and wounds do not heal. Prior to the 18th century, this condition was notorious among long-duration
