Anatomy study note · Lower limb
Adductor magnus
A large triangular muscle with an adductor part and a hamstring part. The adductor hiatus in its insertion lets the femoral vessels pass into the popliteal fossa.
Key points
- Two parts, two nerves (obturator + tibial part of sciatic).
- → linea aspera + adductor tubercle.
- Adductor hiatus → femoral vessels become popliteal.
- Limb muscles: in situ from limb-bud mesenchyme.
- Upper limb bud C4–T2; lower limb bud L2–S2.
- Skeletal muscle: multinucleated, peripheral nuclei, striated.
- Epimysium → perimysium → endomysium.
