2.
In which of the two positions is injury more likely?
Correct Answer
B. Plantarflexion
Explanation
In dorsiflexion, the ankle is locked. In plantarflexion, the ankle can freely invert or evert.
3.
Which of the following is not a thickening of the knee?
Correct Answer
A. Plantar aponeurosis
Explanation
Plantar aponeurosis is the most superficial ligament responsible for maintaining the longitudinal arch of the foot.
4.
What is the superior lateral boundary of the popliteal fossa?
Correct Answer
A. Biceps femoris
Explanation
Gastrocnemius is inferior.
Semi muscles are superior and medial.
5.
What is the correct order of structures in the knee from superficial to deep?(Dr. A said sciatic nerve during lab but the lecture slides say tibial nerve)
Correct Answer
D. Sciatic nerve, popliteal vein, popliteal artery
Explanation
The popliteal artery lies right on top of the femur and is likely ruptured when the femur is broken.
6.
Which has cutaneous distribution?
Correct Answer
B. Inferior gluteal nerve
Explanation
The correct answer is the Inferior gluteal nerve. The cutaneous distribution refers to the area of the skin that is supplied by a particular nerve. The Inferior gluteal nerve innervates the skin over the gluteal region, which is the area of the buttocks. The Superior gluteal nerve also innervates the gluteal region, but it does not have a cutaneous distribution. The Sciatic nerve, on the other hand, is a large nerve that runs down the back of the thigh and does not have a cutaneous distribution in the gluteal region.
7.
Which does not allow for extension of the knee?
Correct Answer
A. Biceps femoris
Explanation
Anterior thigh muscles (Quadriceps) extend the knee.
Posterior thigh muscles (Hamstrings: semi t. semi m. & biceps femoris) flex the knee.
8.
Which is not a branch (or a branch of a branch) of the sciatic nerve?
Correct Answer
B. SapHenous nerve
Explanation
The saphenous nerve branches off the of the femoral nerve. It can be seen in the anterior thigh with its fellow branch, the nerve to vastus medialis.
9.
The quadriceps share a common ________ while the hamstrings share a common ______.
Correct Answer
A. Insertion; origin
Explanation
The point of insertion for the quads is the tibial tuberosity. The quads meet at the quadriceps tendon.
The origin for the hamstrings is the ischial tuberosity.
10.
The superior tibiofibular joint is a _______ joint. The inferior tibiofibular joint is a _______ joint.
Correct Answer
D. Synovial; fibrous
Explanation
Neither move much but they are not the same type of joint, which I thought was interesting.
11.
Which is not part of the floor of the femoral triangle?
Correct Answer
C. Deep fascia of the thigh
Explanation
The roof of the femoral triangle is deep fascia of the thigh.
12.
Your center of gravity runs posterior to the hip joint, anterior to the knee, and anterior to the ankle.
Correct Answer
A. True
Explanation
The statement is true because the center of gravity is the point at which the body's mass is evenly distributed. In the human body, the center of gravity is typically located in the lower abdomen, slightly posterior to the hip joint. It is important to note that the center of gravity is not fixed and can change depending on body position and movement. In standing position, the center of gravity is anterior to the knee and ankle, which helps maintain balance and stability.
13.
Which does not allow for medial rotation of the thigh?
Correct Answer
A. Gluteus maximus
Explanation
Gluteus maximus, piriformis, and triceps coxae laterally rotate the thigh.
Different portions of gluteus medius rotate the thigh medially and laterally.
Gluteus medius, minimus, and maximus are important in abducting the hip.
14.
Which of the following does not pass through the adductor canal?
Correct Answer
E. Sciatic nerve
Explanation
The femoral artery and vein, saphenous nerve, and nerve to vastus medialis pass through the adductor canal.
Adductor canal terminates in the popliteal fossa.
15.
The femoral nerve serves an important role in proprioception of the knee.
Correct Answer
A. True
Explanation
The femoral nerve is a major nerve in the leg that provides sensory information to the knee joint. Proprioception refers to the body's ability to sense the position and movement of its parts. Since the femoral nerve innervates the muscles around the knee joint and provides sensory feedback, it plays a crucial role in proprioception of the knee. Therefore, the statement is true.
16.
Which of the following run behind the lateral malleolus? (posterior)
Correct Answer
B. Short sapHenous vein
Explanation
This was an example question during the September 3rd lecture.
17.
Which is more likely to be damaged?
Correct Answer
A. Medial Meniscus
Explanation
The MCL is attached to the medial meniscus, whereas the lateral meniscus does not have any attachments.
18.
Which of the following is not innervated by the common fibular nerve?
Correct Answer
C. Flexor hallicus longus
Explanation
The tibial nerve innervates flexor hallicus longus as well as the rest of the tarsal tunnel (tibialis posterior and flexor digitorum longus).
The common fibular nerve innervates tibialis anterior as well as extensor hallicus longus, extensor digitorum longus, tibialis anterior, and the peroneals
The peroneals is another name for the fibularis longus and brevis.
