An anatomy chart of the groin area should include the muscles and tendons that attach to the crease where the inner thigh meets the body around the external genitals, explains the MendMeShop. Groin muscles include the hip adductor and hip flexor muscle groups.Continue Reading
The hip adductor muscles are a group of muscles located on the inner thigh, starting in the groin and extending to the inside of the knee, describes the MendMeShop. The short adductor muscles include the pectineus, adductor brevis and adductor longus, and the long adductors are the adductor magnus and gracilis muscles. All adductors attach the pelvis to the femur bone, except the gracilis muscle, which attaches to the tibia bone. Together, the adductors bring the legs together and rotate the hip inwards. The term "groin muscles" commonly refers to these muscles, notes About.com.
The hip flexor muscles lift the upper leg and externally rotate the spine and thigh bone, notes the MendMeShop. Flexor muscles include the outer hip muscle, or fasciae latae; the rectus femoris; sartorius; the psoas major; and the iliacus, or psoas minor. Together, the psoas major and the iliacus make up the iliopsoas. The iliopsoas are deep-set muscles at the front of the pelvis.Learn more about Muscles
