Peroneus brevis
Origin: lateral distal 2/3 of shaft of fibula
Insertion: base of fifth metatarsal
Action: E version of foot; assist plantar flexion of ankle
Peroneus tertius
Origin; anterior distal shaft of Sevilla

Action: E version of foot; assess Dorsiflexion of ankle
Quadricep rectus femoris
Origin: AIIS anterior inferior iliac spine
Insertion: patella and tuberosity of tibia, via patellar ligament
Action: extends knee; flexes hip
Vastus medialis
Origin: posterior femur
Insertion: patella and tuberosity of tibia via the patellar ligament
Action extends need
Vastus intermedius
Origin: anterior femur
Insertion: patella and tuberosity of tibia via patellar ligament
Action: extends knee
Vastus lateralis
Origin: posterior femur
Insertion: patella and tuberosity of tibia via the patellar ligament
Action: extends knee
Sartorius
Origin: ASIS anterior superior iliac spine
Insertion: Pes anserious - medial proximal tibial shaft
Action: flexes, abducts, And laterally rotates thigh at hip; medially rotates leg during knee flexion
Tensor fascia Latae
Origin: iliac crest - ASIS to PSIS
Insertion: lateral condyle of tibia via iliotibial tract
Action: flexes, abducts, and medially rotates thigh
Pectineus
Origin: anterior pubis
Insertion: upper medial and posterior shaft of femur
Action: flexes, adducts, and medially rotates thigh at hip
Adductor Magnus
Origin: anterior pubis to ischial tuberosity
Insertion: linea aspera; adductor tubercle of femur
Action: adducts hip; assist in lateral rotation, flexion (anterior fibers), and extension (posterior fibers) of hip
Gracilis
Origin: anterior pubis
Insertion: Pes anserinus - medial proximal tibial shaft
Action: flexes, adducts, and medial rotates thigh at hip; flexes Knee
The only adductor to attach to pubis and tibia
Shares attachment with adductor longus
Adductor longus
Origin: anterior pubis
Insertion: metal shaft of posterior femur
Action: adducts thigh at hip; laterally rotates thigh
Shares attachment with gracilis
Adductor Brevis
Origin: anterior pubis
Insertion: proximal shaft of posterior femur
Action: adducts thigh at hip; assist in lateral rotation of thigh
Psoas Major
Origin vertebral bodies, intervertebral disc, anterior transverse processes of T12-L5
Insertion: lesser trochanter of the femur
Action: flexes hip; flexes lumbar vertebrae; controls rate of extension of lumbar vertebrae; Proximates lumbar vertebrae toward femur
Iliacus
Origin: inner surface of iliac fossa
Insertion: lesser trochanter of femur
Action: flexes hip
