Ischiocondylar part of adductor magnus
Pars ischiocondylaris adductoris magni
- Synonym: Hamstring part of adductor magnus
Definition
Ischiocondylar part of adductor magnus | |
Origin | Ischial tuberosity |
Insertion | Adductor tubercle of femur |
Artery | Obturator artery |
Innervation | Obturator nerve (L2-L4) |
Action | Hip joint - Thigh extension, thigh internal rotation Entire muscle: Pelvis stabilization |
The ischiocondylar part of the adductor magnus (a.k.a. the harmstring part) refers to the portion of the adductor magnus muscle. It lies deep in the medial compartment of thigh and functions as both a powerful adductor and a weak extensor of the hip joint.
Origin
From the ischial tuberosity (in common with the hamstring group of muscles).
Insertion
To the adductor tubercle on the medial condyle of the femur via a rounded tendon.
Some fibres form the adductor hiatus, a gap between the tendinous insertion of the hamstring part below and the adductor part of the muscle above. The femoral vessels pass through the hiatus to become the popliteal vessels.
Innervation
The ischiocondylar (hamstring) part of adductor magnus is innervated by the sciatic nerve whereas the adductor part is innervated by the obturator nerve.
