Balanitis xerotica obliterans (BXO) or Lichen sclerosus (LS) of the genitalia is a chronic and progressive inflammatory disorder involving the skin of the penis. It commonly affects the foreskin but may also affect the penis and urinary opening as well as the urine tube (urethra).
A long, thin, strap-like muscle; runs diagonal over anterior thigh. O- anterior superior iliac spine I- medial tibial surface A- flexes leg, flexes & laterally rotates thigh
The majority of the muscle rests on the medial side of the thigh, covering nearly half of its anterior surface. The action of this muscle is to adduct and rotate the thigh and extend the shank. The remaining muscles of the thigh are located on the medial surface. This group of muscles originates on the pelvic girdle and inserts on the femur. These muscles act across the hip joint, and their major action is adduction of the thigh. The medial surface of the thigh, posterior to the sartorius and quadriceps group is covered by the gracilis. The gracilis adducts and retracts the leg.
