Iliopsoas Muscle: flexion and medial rotation of the thigh
• O: Ilium and lumbar vertebrae
• I: femur
Gluteus Maximus: extends the thigh
• O: Ilium, sacrum, coccyx• I: femur
Adductors: Longus and Magnus
• Longus: adducts, flexes, laterally rotates
• Magnus: adducts, anterior flexion; posterior extension
• O: coxal bone• I: femur
• #9 = gracilis• Adducts thigh; flexes
and medially rotates the leg
• O: pubis• I: tibia
MUSCLES THAT MOVE THE LEG
Quadriceps(4): Rectus femoris; vastus lateralis; vastus medialis;
vastus intermedius
Vastus intermedius: under rectus femoris: extends the leg
Hamstrings (3): biceps femoris, semitendinosus, semimembranosus:
extension of thigh, flexion of leg
Tibialis Anterior
• Dorsiflexion; foot inversion
• O: tibia• I: tarsal bones and
first metatarsal
Soleus
• Plantar flexion• O: tibia and fibula• I: calcaneus
