Adductor Magnus Muscle -

Because the hamstring portion crosses the knee joint and inserts at the adductor tubercle, it assists in knee flexion, though this is a minor role compared to the true hamstrings.

The adductor magnus has two distinct heads of origin:

The adductor magnus is deep to the gracilis and adductor longus. To palpate it:

Although less commonly strained than the adductor longus, the adductor magnus can be injured during forceful eccentric contractions (e.g., sudden change of direction, wide-based split). Symptoms include deep medial thigh pain, weakness in adduction, and tenderness near the ischial tuberosity or linea aspera. adductor magnus muscle

An injury to the Hamstring part of the Adductor Magnus can mimic a standard hamstring strain, causing pain deep in the back of the thigh or

The adductor magnus is the largest and most powerful muscle in the medial (inner) compartment of your thigh. It is a complex "composite" muscle, meaning it has two distinct parts with different origins, nerve supplies, and functions. 1. Functional Anatomy The muscle is divided into two main sections: Adductor (Pubofemoral) Part: Origin: Inferior pubic ramus and ischial ramus. Insertion: Linea aspera of the femur (posterior side).

Function: Primarily adducts the thigh (pulls it toward the midline) and assists in hip flexion. Hamstring (Ischiocondylar) Part: Origin: Ischial tuberosity (your "sit bone"). Because the hamstring portion crosses the knee joint

Insertion: Adductor tubercle on the medial condyle of the femur (near the knee).

Function: Adducts the thigh and acts as a powerful hip extensor, especially during squats. 2. Key Nerve & Blood Supply

Innervation: It has a dual supply. The adductor part is controlled by the obturator nerve ( L2cap L sub 2 L4cap L sub 4 Symptoms include deep medial thigh pain, weakness in

), while the hamstring part is controlled by the tibial division of the sciatic nerve ( L4cap L sub 4 S3cap S sub 3

Blood Supply: Primarily supplied by the deep femoral artery (profunda femoris) via its perforating branches. 3. Clinical Significance Adductor Strain - StatPearls - NCBI Bookshelf

The adductor magnus has two distinct heads:

| Head | Origin | |------|--------| | Adductor (pubofemoral) head | Inferior ramus of pubis & ramus of ischium | | Hamstring (ischiocondylar) head | Ischial tuberosity |
