Pectineus- Adducts hip
- Flexes hip
- Pectineal line of pubic bone- Upper medial shaft of femur (pectineal line)- Femoral nerve: L2,3,4
- Medial circumflex femoral artery
- Obturator artery
Adductor brevis- Adducts hip
- Laterally rotate hip
- Flexes hip
- Anteroinferior pubic ramus- Pectineal line
- Superomedial part of linea aspera
- Obturator nerve: L2,L3,L4- Medial circumflex femoral artery
- Obturator artery
Adductor longus- Adducts hip
- Laterally rotate hip
- Flexes hip
- Anterior body of pubis- Middle third of linea aspera- Obturator nerve: L2, L3, L4- Medial circumflex femoral artery
- Obturator artery
Adductor magnus- Adducts hip
- Superior vertical fibres flex hip
- Vertical fibres extend hip
- Anteroinferior pubic ramus
- Ischial tuberosity
- Medial linea aspera
- Adductor tubercle
- Obturator nerve: L2,3,4
- Vertical or hamstring portion innervated by tibial nerve: L2, L3, L4
- Medial circumflex femoral artery
- Inferior gluteal artery
- Obturator artery
Gracilis- Adducts hip
- Flexes knee
- Medially rotates knee when flexed
- Lower margin of pubic bone- Superomedial shaft of tibia- Obturator nerve: L2,3,4- Obturator artery
- Medial circumflex femoral artery
Obturator externus
- Lateral rotation of hip
- Assists hip adduction
- Obturator membrane
- Anterior obturator foramen
- Posteromedial surface of greater trochanter of femur- Obturator nerve: L2,3,4
- Vertical or hamstring portion innervated by tibial nerve: L2, L3, L4
- Obturator artery
- Medial circumflex femoral artery
