Question 1

The adductor magnus is innervated by which nerve?

Accepted Answer

C

Question 2

Which of the following muscles is NOT attached to the linea aspera?

Accepted Answer

The vastus intermedius muscle is not attached to the linea aspera; it originates from the anterior and lateral surfaces of the femur.

Question 3

Tapping the patellar ligament in a normal individual stimulates reflex contraction of the muscles that insert on the patella. Destruction of which of the following nerves would eliminate the knee jerk response?

Accepted Answer

The femoral nerve is responsible for innervating the quadriceps femoris muscle group, which is involved in the knee jerk (patellar) reflex. Destruction of the femoral nerve would eliminate this reflex response.

Question 4

The anterior and posterior tibial arteries begin at the level of the:

Accepted Answer

The anterior and posterior tibial arteries begin at the level of the popliteus muscle, where the popliteal artery divides into these two branches.

Question 5

The short head of the biceps femoris muscle functions in:

Accepted Answer

The answer of The short head of the biceps femoris...

Question 6

Which of the following muscles originates from the ischial tuberosity?

Accepted Answer

The inferior gemellus muscle originates from the ischial tuberosity.

Question 7

Which of the following is an important bony relationship of the common fibular nerve?

Accepted Answer

The common fibular nerve winds around the neck of the fibula, making it an important bony landmark for this nerve.

Question 8

Which of the following muscles is in the lateral compartment of the leg?

Accepted Answer

The fibularis brevis muscle is located in the lateral compartment of the leg, which is primarily responsible for eversion of the foot.

Question 9

The fibularis brevis muscle functions in:

Accepted Answer

The fibularis brevis muscle, located on the lateral side of the leg, primarily functions in plantarflexion and eversion of the foot. Plantarflexion refers to the movement that decreases the angle between the sole of the foot and the back of the leg, as in pressing down on a gas pedal. Eversion is the movement of the sole of the foot away from the median plane.

Question 10

Which two muscles attach to the iliotibial tract (band)?

Accepted Answer

The iliotibial tract (band) is attached to by the gluteus maximus and tensor fascia latae muscles. These muscles work together to stabilize the knee and hip during activities.

Question 11

The 'keystone' bone(s) of the transverse arch is/are the:

Accepted Answer

The keystone bones of the transverse arch of the foot include the cuneiforms 1, 2, 3, and the metatarsals 1-5. These bones play a crucial role in maintaining the structure and function of the transverse arch.

Question 12

Which of the following tarsal bones transmits the weight of the body from the tibia to all other weightbearing bones of the foot?

Accepted Answer

The talus is the tarsal bone that transmits the weight of the body from the tibia to the other weightbearing bones of the foot. It sits directly below the tibia and is a key bone in the ankle joint, playing a crucial role in the distribution of weight and movement.

Question 13

The gluteus maximus muscle is innervated by which nerve?

Accepted Answer

The gluteus maximus muscle is innervated by the inferior gluteal nerve.

Question 14

The prominent feature of the proximal end of the tibia is/are the:

Accepted Answer

The proximal end of the tibia is characterized by its condyles, which are the medial and lateral condyles. These structures articulate with the femur to form the knee joint.

Question 15

Which of the following statements concerning the superficial venous drainage of the lower limb is INCORRECT?

Accepted Answer

The great saphenous vein terminates at the femoral vein, not the external iliac vein.

Question 16

All the following muscles function in lateral rotation of the thigh at the hip joint EXCEPT:

Accepted Answer

The gluteus minimus primarily functions in medial rotation and abduction of the thigh, not lateral rotation, unlike the other muscles listed which assist in lateral rotation of the thigh at the hip joint.

Question 17

The calcaneonavicular (spring) ligament is important for maintaining which arch(es) of the foot?

Accepted Answer

The calcaneonavicular (spring) ligament supports the medial longitudinal arch of the foot.

Question 18

Which of the following muscles extends the femur and flexes the knee?

Accepted Answer

The semimembranosus is a hamstring muscle that extends the femur at the hip and flexes the knee.

Question 19

Which of the following bones is NOT part of the lateral longitudinal arch?

Accepted Answer

The navicular bone is part of the medial longitudinal arch, not the lateral longitudinal arch. The lateral arch consists of the calcaneus, cuboid, and the fourth and fifth metatarsals.

Question 20

The lateral plantar artery is a branch of which artery?

Accepted Answer

The lateral plantar artery is a branch of the posterior tibial artery. It is one of the terminal branches, with the other being the medial plantar artery, and it supplies the lateral part of the sole of the foot.
