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)
- A.
Popliteal artery, popliteal vein, sciatic nerve
- B.
Popliteal vein, popliteal artery, sciatic nerve
- C.
Sciatic nerve, popliteal artery, popliteal vein
- D.

Which has cutaneous distribution?
- A.
Superior gluteal nerve
- B.
Inferior gluteal nerve
- C.
Sciatic nerve
Correct Answer
B. Inferior gluteal nerveExplanation
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.Rate this question:

Which does not allow for extension of the knee?
- A.
Biceps femoris
- B.
Vastus lateralis
- C.
Rectus femoris
Correct Answer
A. Biceps femorisExplanation
Anterior thigh muscles (Quadriceps) extend the knee.
Posterior thigh muscles (Hamstrings: semi t. semi m. & biceps femoris) flex the knee.Rate this question:

Which is not a branch (or a branch of a branch) of the sciatic nerve?
- A.
Tibial nerve
- B.
Saphenous nerve
- C.
Common fibular nerve
- D.
Sural nerve
Correct Answer
B. SapHenous nerveExplanation
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.Rate this question:

- 9.
The quadriceps share a common ________ while the hamstrings share a common ______.
- A.
Insertion; origin
- B.
Origin; insertion
Correct Answer
A. Insertion; originExplanation
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.Rate this question:

Your center of gravity runs posterior to the hip joint, anterior to the knee, and anterior to the ankle.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
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.Rate this question:

Which does not allow for medial rotation of the thigh?
- A.
Gluteus maximus
- B.
Gluteus minimus
- C.
Tensor fascia latae
- D.
Gluteus medius
Correct Answer
A. Gluteus maximusExplanation
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.Rate this question:

- C.
Saphenous nerve
- D.
Nerve to vastus medialis
- E.

The femoral nerve serves an important role in proprioception of the knee.
- A.
True
- B.
False
Correct Answer
A. TrueExplanation
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.Rate this question:

Which of the following is not innervated by the common fibular nerve?
- A.
Peroneals
- B.
Tibialis anterior
- C.
Flexor hallicus longus
Correct Answer
C. Flexor hallicus longusExplanation
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.Rate this question:
