29. Dissection of Anterior and Medial Thigh

Question 1

The great saphenous vein drains into the popliteal vein in the popliteal fossa. True or False?

Answer 1

False - its runs the entire length of the lower limb and drains into the femoral vein.

Question 2

The lateral border of the femoral triangle is formed by the lateral border of the sartorius muscle. True or False?

Answer 2

False - is formed by the MEDIAL border of the sartorius muscle.

Question 3

The gracilis muscle arises from the bones of the pelvis to insert into the proximal tibia with the semimembranosus and sartorius muscle. True or False?

Answer 3

False - it arises for the bones of the pelvis to insert into the proximal tibia with the SEMITENDINOSUS and sartorius muscle.

Question 4

The obturator externus muscle arises from the obturator membrane and inserts onto the trochanteric fossa, acting to laterally rotate the thighs at the hip joint. True or False?

Answer 4

True

Question 5

The muscles of the anterior compartment of the thigh receive blood from the femoral artery. True or False?

Answer 5

True

Question 6

Answer 7

Pectineus

Question 8

Answer 8

Sartorius

Question 9

What is the correct organisation of the structures of the femoral triangle from lateral to medial?

artery, vein, canal, nerve

artery, vein, nerve, canal

nerve, artery, vein, canal

nerve, vein, canal, artery

vein, nerve, artery, canal

Answer 9

nerve, artery, vein, canal

Question 10

Which nerve innervates all, except one, of the muscles of the medial compartment of the thigh?

Answer 10

Obturator nerve

Question 11

Answer 11

Question 12

Which muscles are contained in the anterior compartment?

Answer 12

Sartorius
Vastus medialis, intermedius & lateralis
Rectus femoris

Question 13

Find the rectus femoris and quadriceps tendon

Answer 13

Question 14

Find the vastus medialis muscle

Answer 14

Question 15

Answer 15

Question 16

Which muscles attach to these points?

Answer 16

Question 17

What blood vessels and nerves are contained in the femoral triangle?

Find iliopsoas muscle

Answer 17

The common femoral artery, common femoral vein and femoral nerve are located within the femoral triangle anterior to the iliopsoas. The lateral femoral cutaneous nerve is between the tensor fascia lata and sartorius muscles.
