Lower Limb Anatomy MCQs 3

The biceps femoris muscle:

• Flexes the hip

• Flexes the knee and laterally rotates the leg

• Is innervated by the obturator nerve

• Inserts onto the tibial tuberosity

• Is located in the anterior thigh compartment

The popliteal artery:

• Is a direct continuation of the femoral artery

• Divides into the anterior and posterior tibial arteries

• Supplies the anterior compartment of the leg

• Passes anterior to the knee joint

• Gives off the deep femoral artery

The medial collateral ligament (MCL) of the knee:

• Is attached to the lateral meniscus

• Is not connected to the joint capsule

• Prevents valgus deformity

• Is tight in knee flexion

• Originates from the fibula

The anterior compartment of the leg:

• Contains the tibialis posterior muscle

• Is innervated by the tibial nerve

• Contains muscles responsible for dorsiflexion

• Is supplied by the posterior tibial artery

• Contains the peroneus longus muscle

The femoral nerve:

• Is a branch of the sacral plexus

• Innervates the adductor magnus

• Supplies the quadriceps femoris muscle

• Passes through the adductor canal

• Provides cutaneous innervation to the medial thigh

The lateral compartment of the leg:

• Contains the tibialis anterior muscle

• Contains muscles responsible for plantarflexion

• Is supplied by the superficial peroneal nerve

• Contains the deep peroneal nerve

• Contains the extensor digitorum longus muscle

The pes anserinus:

• Is a bony prominence on the femur

• Consists of the tendons of the semimembranosus, gracilis, and sartorius

• Is located on the lateral side of the knee

• Includes the tendons of the sartorius, gracilis, and semitendinosus

• Provides attachment for the quadriceps muscle

The fibular head:

• Serves as the attachment for the biceps femoris tendon

• Is the origin of the tibialis anterior muscle

• Articulates with the medial condyle of the tibia

• Provides attachment for the anterior cruciate ligament

• Receives blood supply from the posterior tibial artery

The acetabulum:

• Is located on the distal femur

• Is completely covered by articular cartilage

• Is deepened by the acetabular labrum

• Articulates with the greater trochanter

• Provides insertion for the rectus femoris muscle

The deep femoral artery:

• Is a direct continuation of the femoral artery

• Supplies the muscles of the anterior compartment of the leg

• Gives off perforating branches to supply the thigh

• Passes through the adductor hiatus

• Supplies the skin over the knee
