Adductor magnus (Musculus adductor magnus)
Educational content only — not medical advice.
Anatomy
The largest medial thigh muscle: a giant triangle from pubis and ischium to the whole linea aspera and adductor tubercle — its upper part adductor, its lower (hamstring) part ischial — a double-identity muscle.
Origin & insertion
Inferior pubic ramus, ischial ramus and tuberosity along a continuous line.
Action
Powerfully adducts and steadies the thigh in push-off; its hamstring portion genuinely extends the hip.
Innervation
Obturator nerve (adductor part) and tibial nerve (hamstring part) — a true neural split.
Clinical notes
Its distal opening (adductor hiatus) transmits the femoral vessels to the popliteal fossa; deep-squat strain is the classic "upper inner thigh" pain of weightlifters.
