  1. Muscles of the Hip, Leg, & Foot

  2. Hip • Gluteus Maximus • Butt • Gluteus Medius

  3. Gluteus Maximus • Function: Extends and rotates the thigh • Origin: Pelvis and sacrum • Insertion: Femur (posterior)

  4. Gluteus Medius • Function: Extends and rotates the thigh • Sits above the gluteus maximus • Origin: pelvis (posterior) • Insertion: top of femur

  5. Upper Leg • Sartorius • “Hacky-Sack” Muscle • Quadriceps Muscles • Quads • Hamstring Muscles • Hammies

  6. Sartorius • Function: flexes lower leg • Longest muscle in the body (anterior) • Origin: pelvis • Insertion: medial side of tibia

  7. Quadriceps Muscles • Quadriceps • 4 muscles make up the “Quad” on the anterior side of leg • Function: Extends the leg & knee and flexes of the hip & thigh

  8. Quadriceps • Origin: Lower part of the pelvis and top of the femur • Insertion:patella (knee cap) • Rectus Femoris • Located next to the sartorius • Vastus Lateralis • Located on the outside of your thigh • Vastus Medialis (VMO) • Located on the inside of your thigh • Vastus Intermedius • Located next to the vastus lateralis

  9. Hamstring Muscles • 3 muscles make up the hamstring • It is located on the posterior side of the leg • Function: Flexes the leg and extends the thigh

  10. Hamstring Muscles • Origin: Back ofPelvis • Insertion:Tibia(inside & outside) • Biceps Femoris • Outside hamstring muscle • Semimembranosus • Inside hamstring muscle • Semitendinosus • Middle hamstring muscle

  11. Lower Leg • Gastrocnemius (Calf) • Tibialis Anterior • Extensor Digitorum Longus • Peroneus Longus • Peroneus Brevis

  12. Gastrocnemius • Function: (posterior) extends or depresses the foot when standing or walking; points the foot down • Origin: bottom of the femur • Insertion: heel bone (calcaneus)

  13. Tibialis Anterior • Function: flexes the foot muscle on your shin bone • Origin: Tibia • Insertion: Metatarsal

  14. Extensor Digitorum Longus • Function: Moves your toes/digits 2-5 • Origin: top of tibia and fibula • Insertion: Phalanges (2-5) • Located next to tibialisanterior on the outside of the leg

  15. Peroneus Longus • Function: Flexes the foot; archsupport muscle (side of leg) • Origin: Fibula • Insertion: Bigtoe (1st metatarsal)

  16. Peroneus Brevis • Function: Flexesfoot; archsupport muscle • Origin: shaft of fibula • Insertion: your little toe (outside lower leg)
