Gracilis
Origin: Inferior ramus of pubis
Insertion: Proximal, medial shaft of the tibia at pes anserinus tendon
Action: - Hip adduction
- Hip medial rotation
- Knee flexion
- Knee medial rotation when flexed
Adductor Longus
Origin: Pubic tubercle
Insertion: Medial lip of linea aspera
Action: - Hip adduction
- Hip medial rotation
- Hip flexion (assist)
Adductor Magnus
