| Muscle | Action | Origin | Insertion | Innervation | Blood supply |
|---|---|---|---|---|---|
| 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 |
