Muscles of the Hip, Leg, & Foot
Hip
Gluteus Maximus Butt
Gluteus Medius
Gluteus Maximus Function: Extends
and rotates the thigh Origin: Pelvis and
sacrum Insertion: Femur
(posterior)
Gluteus Medius Function:
Extends and rotates the thigh Sits above the
gluteus maximus Origin: pelvis
(posterior) Insertion: top of
femur
Upper Leg
Sartorius “Hacky-Sack” Muscle
Quadriceps Muscles Quads
Hamstring Muscles Hammies
Sartorius Function: flexes
lower leg Longest muscle in
the body (anterior) Origin: pelvis Insertion: medial
side of tibia
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
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
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
Hamstring Muscles Origin: Back of Pelvis Insertion: Tibia (inside & outside)
Biceps Femoris Outside hamstring muscle
Semimembranosus Inside hamstring muscle
Semitendinosus Middle hamstring muscle
Lower Leg
Gastrocnemius (Calf) Tibialis Anterior Extensor Digitorum Longus Peroneus Longus Peroneus Brevis
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)
Tibialis Anterior Function: flexes
the foot muscle on your shin bone Origin: Tibia Insertion:
Metatarsal
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
Peroneus Longus Function: Flexes
the foot; arch support muscle (side of leg) Origin: Fibula Insertion: Big toe
(1st metatarsal)
Peroneus Brevis Function: Flexes
foot; arch support muscle Origin: shaft of
fibula Insertion: your
little toe (outside lower leg)
