Knee And Leg MCQ Quiz: Test!

The correct answer is the Medial malleolar artery. The Posterior tibial artery gives rise to several branches, including the Peroneal artery, Medial plantar artery, and Lateral plantar artery. However, the Medial malleolar artery is not a branch of the Posterior tibial artery.

The great saphenous vein terminates by piercing the saphenous opening and draining into the femoral vein. This means that the great saphenous vein, after traveling up the leg, passes through a specific opening called the saphenous opening and empties its contents into the femoral vein. This is an important aspect of the superficial drainage of the lower limb as it allows for the return of deoxygenated blood from the lower limb back to the heart for oxygenation.

The calcaneal branches are derived from the posterior tibial.

The popliteal artery is not the most superficial structure of the popliteal fossa.

The popliteal fossa is a diamond-shaped space located at the back of the knee joint. It is bounded by various structures. The inferior border of the popliteal fossa is formed by the heads of the Gastrocnemius muscle, which is the largest muscle in the calf region. The heads of the Gastrocnemius muscle originate from the femur and merge to form the Achilles tendon. This muscle plays a crucial role in the movement of the foot and ankle. Therefore, it is correct to say that the inferior border of the popliteal fossa is made up of the heads of Gastrocnemius.

PL attaches to the 1st metatarsal and medial cuneiform
PL is important in maintaining the transverse arch of the foot
PL & PB have a shred synovial sheath at the ankle

The popliteal fossa is a diamond-shaped space located at the back of the knee joint. It contains various structures including the short saphenous vein, superficial and deep lymph nodes, and the plantaris muscle. However, the superficial peroneal nerve is not contained within the popliteal fossa. It is a branch of the common peroneal nerve that runs superficially down the leg and supplies sensation to the anterior and lateral aspects of the leg and foot.

The question is asking for a branch of the Posterior tibial artery that is not included in the given options. The options include Peroneal artery, Medial malleolar branch, Lateral calcaneal branches, and Medial plantar artery. The correct answer is Medial malleolar branch, which means that this branch is not a part of the Posterior tibial artery.

The tendon of FHL passes below the malleolus The medial collateral ligament (deltoid ligament) is the stronger of the two The posterior tibial artery is separated from the medial malleolus by the tendons of Tibialis posterior and FDL.

The correct answer explains that the stability of the weight bearing flexed knee is provided by the Posterior cruciate ligament. This means that when the knee is bent and supporting weight, the Posterior cruciate ligament helps to prevent excessive movement or instability in the joint. It plays a crucial role in maintaining the structural integrity and function of the knee during weight-bearing activities.

The Deep peroneal nerve provides cutaneous innervation to the skin of the 1st dorsal webspace

The correct answer states that Peroneus brevis attaches distally to the lateral border of the base of the 5th metatarsal. This is an accurate statement about the muscles of the lateral compartment of the leg. The attachment of Peroneus brevis to the 5th metatarsal is important for the function of the muscle in eversion of the foot and stabilization of the ankle joint.

The correct answer is that the peroneal artery lies medial to the fibula. This means that the artery is positioned on the side of the leg that is closer to the body's midline, rather than on the outer side where the fibula is located. This anatomical knowledge is important for understanding the location and course of the peroneal artery in relation to other structures in the leg.

The transverse arch is supported by the ligaments of Peroneus longus and Tibialis posterior acting like a stirrup across the arch. This means that these ligaments provide support and stability to the transverse arch, helping to maintain its shape and prevent it from collapsing. The ligaments act like a stirrup, similar to how a stirrup supports the foot in a horse's saddle, providing additional reinforcement to the arch.

The Popliteus muscle does not attach distally to the posterior tibia distal to the soleal line.

The correct answer is Extensor digitorum longus & Peroneus tertius. These two muscles share a synovial sheath, which is a protective covering that surrounds the tendons of the muscles. This synovial sheath helps to reduce friction and allows for smooth movement of the tendons.

The Posterior tibial artery is separated from the medial malleolus by the tendons of Tibialis posterior and Flexor digitorum longus. The artery lies between the tendons of FDL and Flexor hallucis longus distal to the malleolus

The peroneal bursa does not communicate with the synovial cavity of the knee. Bursae are small fluid-filled sacs that reduce friction between tissues such as bones, tendons, and muscles. In the knee joint, the suprapatellar bursa is located above the patella, the gastrocnemius bursa is located behind the knee, and the anserine bursa is located on the medial side of the knee. However, the peroneal bursa is not directly connected to the synovial cavity of the knee.

The Anterior tibial artery is crossed by the tendon of EHL at the ankle. EHL initially lies lateral before crossing and becoming medial.

It originates beneath the fibrous arch of soleus and the distal border of soleus
It descends between TA and EDL in the leg before being crossed by EHL in the ankle to lie between it and TA
It terminates as Dorsalis pedis
