Adductor brevis distal attachment
Pectineal line and proximal part of linea aspera of femur
Adductor brevis innervation
Obturator nerve, branch of, anterior division (L2, L3, L4)
Adductor brevis main action
Adducts thigh; to
some extent flexes it
Adductor magnus proximal attachment
Adductor part: inferior ramus of pubis, ramus of ischium

Adductor magnus distal attachment
Adductor part: gluteal tuberosity, linea aspera, medial supracondylar line
Hamstring part: adductor tubercle of femur
Adductor magnus innervation
Adductor part: obturator nerve (L2, L3, L4), branches of posterior division
Hamstring part: tibial part of sciatic nerve (L4)
Adductor magnus main action
Adducts thigh Adductor part: flexes thigh Hamstrings part: extends thigh
Gracilis proximal attachment
Body and inferior ramus of pubis
Gracilis distal attachment
Superior part of medial surface of tibia
Gracilis innervation
Obturator nerve (L2, L3)
Gracilis main action
Adducts thigh; flexes leg; helps rotate leg medially
