What is the role of Gracilis in hip and knee joint?

Gracilis acts on the hip and knee joints, resulting in several movements: Strong leg flexion and medial (internal) rotation around the knee joint when the knee is in a semiflexed position. Weak thigh flexion and adduction around the hip joint, simply aiding the other, more powerful thigh adductors.

What muscle extends from the coxal bone to the tibia?

Gracilis extends from the coxal bone to the tibia and thanks to it, you are capable of thigh adduction and flexion, as well as leg flexion and medial (internal) rotation. These actions have several important roles, for instance to balance the trunk during walking. Key facts about the gracilis muscle. Origin.

What muscle is the Pes Anserinus?

S artorius muscle. G racilis muscle. S emitendinosus muscle. Pes anserinus, and hence the gracilis muscle, attaches to the medial surface of proximal tibia inferior to the condyle.

What is the most superficial muscle in the medial thigh?

Relations. Gracilis is the most superficial muscle of the medial (adductor) compartment of the thigh. It is overlaid superficially by the skin and subcutaneous tissue, while its medial part is also covered by the deep layer of fascia lata.

How to test gracilis?

To test the anatomy and range of movements of the gracilis, the patient needs to flex the leg against resistance and rotate it medially. This combination evidentiates the location of the gracilis tendon superomedially to the popliteal fossa of the knee. It is the most medial and anterior, or upper, tendon of this region. The gracilis can be palpated all the way to its origin if the tendon is traced proximally. Testing the movements of the gracilis is carried out by flexing the patient’s knee to approximately ninety degrees, internally rotating the leg, and maintaining these positions while adducting the thigh.

Which tendon is more proximally attached to the pes anserinus?

Within the pes anserinus, the gracilis tendon attaches more proximally than the tendons of semitendinosus and sartorius. Some tendinous fibers of the gracilis slip into the deep fascia of the lower leg while others can often blend with the tendon of the medial head of gastrocnemius muscle .

Which tendon passes through the medial condyle of the femur?

The muscle fibers travel inferiorly and eventually blend into a round tendon which courses posterior to the sartorius tendon and passes the medial condyle of femur. At the level of the proximal part of tibia, the gracilis tendon curves and then fans out around the medial condyle of tibia.

Where does the Sartorius muscle originate?

The sartorius muscle originates by a round tendon from the anterior superior iliac spine and the upper half of the notch between the anterior superior iliac spine and the anterior inferior iliac spine. The fibers form a thin, flat muscle, which extends inferomedially across the anterior surface of the thigh.

Which muscle is deep to the sartorius?

Deep to the sartorius is the quadriceps femoris muscle. As it crosses from the lateral to the medial side of the thigh, the sartorius muscle crosses the surfaces of the iliopsoas, pectineus and adductor longus muscles. The tensor fasciae latae muscle originates just lateral to the proximal attachment of the sartorius muscle.

What muscle is the pes anserine bursa located at?

The pes anserine bursa located at the insertion of the sartorius muscle can become inflammed (pes anserine bursitis) when chronically overstrained (e.g. when jogging or breaststroking).

What is the longest muscle in the human body?

Sartorius muscle (Musculus sartorius) The sartorius muscle is the longest muscle in the human body. Together with the quadriceps femoris, it belongs to the anterior muscles of the thigh. The sartorius muscle has an oblique course throughout the thigh; it arises from the anterior superior iliac spine, crosses to the medial side of the thigh, ...

What is the pes anserinus?

The inserting tendons of these three muscles form a wide aponeurotic sheath called the pes anserinus. Some fibers from the inferior part of the tendon blend with the medial collateral ligament of the knee joint, and the deep fascia over the medial aspect of the leg, while some superior fibers blend with the knee joint capsule. These connections contribute to the medial stability of the knee joint.

Which muscle is the medial margin of the adductor longus muscle?

The triangle is completed superiorly by the inguinal ligament and medially by the medial margin of the adductor longus muscle. The structures found within the triangle, the femoral artery, vein and nerve, therefore, lie medial to the sartorius. The femoral artery continues inferiorly, deep to the sartorius.

Where does the Tensor Fasciae Latae originate?

The tensor fasciae latae muscle originates just lateral to the proximal attachment of the sartorius muscle. The medial edge of the sartorius forms the lateral border of an important anatomical space known as the femoral triangle.

Which muscles assist with flexion of the thigh at the hip?

Gluteus Maximus. Semitendinosus. Semimembranosus. Biceps femoris (long head) Adductor magnus (posterior) Pectineus , sartorius, and psoas minor also assist with flexion of the thigh at the hip. Muscle Pain Information: The rectus femoris muscle contributes to weak, stiff, painful knees.

Which fasciae assist with extension of the knee through the iliotibial band?

Tensor fasciae latae assists with extension of the knee through the iliotibial band.
