Muscles of the medial compartment of the thigh groin muscles (only thigh has medial compart) All adduct the tight at hip (when riding horse: pectineus (also flex thigh at hip, adductor longus (also flex thigh at hip, * gracilis also crosses knee joint to flex leg. Deep group: adductor brevis flexes thigh, ** adductor magnus extends thigh. Insertion: along lesser trochanter to linea aspera on posterior femur. Action: adducts, flexes and medially rotates the thigh. Origin: inferior ramus and body of pubis and ischial ramus. Action: adducts thigh, flexes and medially rotates the leg (walking) Origin: ischial and pubic rami, and ischial tuberosity. Insertion: linea aspera; supracondylar line and adductor tubercle of the femur. Action: anterior fibers adduct and medially rotate and flex thigh; posterior fibers is synergistic with hamstrings during thigh extension.
