The thigh is the part of lower limb located between the hip and the knee. It can be divided into anterior, medial and posterior compartments that surround the femur. These compartments are formed by the inter muscular septa that originates on the inner surface of fascia lata and attach to the linea aspera of the femur
Anterior compartment of thigh or extensor compartment
Anterior compartment includes the anterior thigh muscles which and extension as action on knee joint and flexion on hip joint. The flexors of hip include the pectineus, iliopsoas, sartorius. Extensors at knee joint is Quadriceps femoris. Quadriceps is a four group of muscles namely vastus lateralis, vastus medialis, vastus intermedius and rectus femoris. They connect to the patella via the quadriceps tendon which then extend to insert at the tuberosity of tibia. It receives innervation by Femoral Nerve. Sartorius originate from the ASIS and insert at the superior, medial surface of tibia and is innervated by femoral nerve.Medial compartment of thigh or adductor compartment
There are five muscles in the group; gracilis, obturator externus, adductor brevis, adductor longus and adductor magnus . All the medial thigh muscles are innervated by the Obturator nerve which arises from the lumbar plexus. Adductor Magnus is the largest muscle in the medial compartment of thigh. It is comprised of two parts- an adductor component and a hamstring component. These muscles originate from pelvis and attach on the femur. Gracilis is the most superficial and medial of the muscles. It crosses at both hip and knee joint. It leads to adduction of thigh at the hip and flexion of the leg at the knee.Front and medial side of Thigh FAQs
