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

10 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

11 Hamstring Muscles  Origin: Back of Pelvis  Insertion: Tibia (inside & outside)  Biceps Femoris Outside hamstring muscle  Semimembranosus Inside hamstring muscle  Semitendinosus Middle hamstring muscle

13 Lower Leg  Gastrocnemius (Calf)  Tibialis Anterior  Extensor Digitorum Longus  Peroneus Longus  Peroneus Brevis

14 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)

15 Tibialis Anterior  Function: flexes the foot muscle on your shin bone Origin: Tibia Insertion: Metatarsal

16 Extensor Digitorum Longus  Function: Moves your toes/digits 2-5 Origin: top of tibia and fibula Insertion: Phalanges (2-5) Located next to tibialis anterior on the outside of the leg

17 Peroneus Longus  Function: Flexes the foot; arch support muscle (side of leg) Origin: Fibula Insertion: Big toe (1 st metatarsal)

18 Peroneus Brevis  Function: Flexes foot; arch support muscle Origin: shaft of fibula Insertion: your little toe (outside lower leg)
