The medial compartment of thigh is one of the
fascial compartments of the thigh and contains the
hip adductor muscles and the
gracilis muscle
The gracilis muscle (; Latin for "slender") is the most superficial muscle on the medial side of the thigh. It is thin and flattened, broad above, narrow and tapering below.
Structure
It arises by a thin aponeurosis from the anterior margins o ...

The
obturator nerve
The obturator nerve in human anatomy arises from the ventral divisions of the second, third, and fourth lumbar nerves in the lumbar plexus; the branch from the third is the largest, while that from the second is often very small.
Structure
The ob ...
is the primary nerve supplying this compartment. The
obturator artery
The obturator artery is a branch of the internal iliac artery that passes antero-inferiorly (forwards and downwards) on the lateral wall of the pelvis, to the upper part of the obturator foramen, and, escaping from the pelvic cavity through the obt ...
is the blood supply to the medial thigh.
The muscles in the compartment are:
*
gracilis
*
adductor longus
In the human body, the adductor longus is a skeletal muscle located in the thigh. One of the adductor muscles of the hip, its main function is to adduct the thigh and it is innervated by the obturator nerve. It forms the medial wall of the fem ...
*
adductor brevis
The adductor brevis is a muscle in the thigh situated immediately deep to the pectineus and adductor longus. It belongs to the adductor muscle group. The main function of the adductor brevis is to pull the thigh medially. The adductor brevis ...

adductor magnus Adductor may refer to:
* One of the anatomical terms of motion
* Adductor muscle (disambiguation)
* Adductor canal
The adductor canal, also known as the subsartorial canal or Hunter’s canal, is an aponeurotic tunnel in the middle third of the th ...
The
obturator externus muscle
The external obturator muscle, obturator externus muscle (; OE) is a flat, triangular muscle, which covers the outer surface of the anterior wall of the pelvis.
It is sometimes considered part of the medial compartment of thigh, and sometimes c ...
is sometimes considered part of this group,
and sometimes excluded.
(Spatially, it is in this location, but functionally, it is more similar to the other
lateral rotator group
The lateral rotator group is a group of six small muscles of the hip which all externally (laterally) rotate the femur in the hip joint. It consists of the following muscles: piriformis, gemellus superior, obturator internus, gemellus inferior, q ...
muscles).
The
pectineus is sometimes included in this group,
and sometimes excluded.
It has the same function as the others in this group, but different innervation – namely, the femoral nerve.
