Anatomy - MOINA of the Medial Compartment of the Thigh

origin of gracilis

inferior ramus of pubis, ramus of ischium

insertion of gracilis

upper part of shaft of tibia on medial surface

innervation of gracilis

obturator nerve

action of gracilis

• adducts thigh at hip joint

• flexes leg at knee joint

origin of adductor longus

body of pubis, medial to pubic tubercle

insertion of adductor longus

posterior surface of shaft of femur (linea aspera)

innervation of adductor longus

obturator nerve

action of adductor longus

adducts thigh at hip joint and assists in lateral rotation

origin of adductor brevis

inferior ramus of pubis

insertion of adductor brevis

posterior surface of shaft of femur (linea aspera)

innervation of adductor brevis

obturator nerve

action of adductor brevis

adducts thigh at hip joint and assists in lateral rotation

origin of adductor magnus

inferior ramus of pubis, ramus of ischium, ischial tuberosity

insertion of adductor magnus

posterior surface of shaft of femur, adductor tubercle of femur

innervation of adductor magnus

• adductor portion: obturator nerve

• hamstring portion: sciatic nerve

action of adductor magnus

• adducts thigh at hip joint and assists in lateral rotation

• hamstring portion: extends thigh at hip joint

origin of obturator externus

outer surface of obturator membrane and pubic and ischial rami

insertion of obturator externus

medial surface of greater trochanter

innervation of obturator externus

obturator nerve

action of obturator externus

laterally rotates thigh at hip joint
