QUIZ 6 ARTERIAL SUPPLY

Question 1

• the continuation of the external iliac artery as it enters the thigh; the name changes as it passes deep to the inguinal ligament
• the femoral artery continues to the adductor hiatus; after the artery passes through the adductor hiatus the name changes to the popliteal artery

Answer 1

Femoral Artery / Superficial Femoral Artery

Question 2

• the lateral branch from the femoral artery near the inguinal ligament
• a small cutaneous artery
• supplies the skin over the anterior superior iliac spine and the inguinal
  ligament
• similar course as the deep circumflex iliac artery

Answer 2

Superficial Circumflex Iliac Artery

Question 3

• the anterior branch from the femoral artery near the inguinal ligament
• a small cutaneous artery
• supplies the skin of inferomedial abdomen

Answer 3

Superficial Epigastric Artery

Question 4

• the medial branch from the femoral artery near the inguinal ligament
• a small cutaneous artery
• divides into superficial and deep branches
• supply the skin of the urogenital triangle

Answer 4

External Pudendal Artery

Question 5

• large posterolateral branch from the femoral artery, 1-2” distal to the
  inguinal ligament

Answer 5

Profunda Femoris Artery / Deep Femoral Artery

Question 6

• last branch of the femoral artery, just proximal to the adductor hiatus
• is part of the genicular anastomosis since both of its branches enter this anastomosis

Answer 6

Descending Genicular Artery / Highest Genicular Artery

Question 7

• passes superficially through the subsartorial fascia and at the medial
  knee region, continues with the saphenous nerve for a short distance
• a branch joins the genicular anastomosis

Answer 7

Saphenous Artery

Question 8

• passes distally, to the knee and joins the genicular anastomosis

Answer 8

Articular Artery

Question 9

• this major branch of the femoral artery passes posterior, intermediate to the pectineus muscle and the adductor longus muscle; it then passes inferiorly, anterior to both the adductor brevis and adductor magnus muscles (these are posterior to adductor longus muscle), to its termination

Answer 9

Profunda Femoris Artery / Deep Femoral Artery

Question 10

• a branch classically from the lateral aspect of the profunda femoris artery
• occasionally from the femoral artery
• divides into 3 terminal branches

Answer 10

Lateral Femoral Circumflex Artery

Question 11

• passes superolaterally along the femoral intertrochanteric line
• supplies the greater trochanter and the head and neck of the femur
• joins the trochanteric anastomosis

Answer 11

Ascending Branch of the LFCA

Question 12

• passes anterolaterally around the femur at the distal edge of the proximal extremity
• provides muscular branches
• joins the cruciate anastomosis

Answer 12

Transverse Branch of the LFCA

Question 13

• passes inferiorly in the anterior compartment of the thigh, intermediate to the rectus femoris muscle and vastus intermedius muscles at their lateral edges, near vastus lateralis muscle
• provides muscular branches and joins the genicular anastomosis

Answer 13

Descending Branch of the LFCA

Question 14

• a branch classically from the medial side of the profunda femoris artery
• occasionally from the femoral artery
• divides into 3 terminal branches

Answer 14

Medial Femoral Circumflex Artery

Question 15

• passes superolaterally along the intertrochanteric crest of the femur
• supplies the greater trochanter and the head and neck of the femur
• joins the trochanteric anastomosis

Answer 15

Ascending Branch of the MFCA

Question 16

• passes posterolaterally around the femur at the inferior edge of the proximal extremity
• provides muscular branches
• joins the cruciate anastomosis

Answer 16

Transverse Branch of the MFCA

Question 17

• passes inferiorly in the medial compartment of the thigh
• provides muscular branches
• adductor brevis muscle is the landmark for the first, second and third perforating arteries of profunda femoris artery

Answer 17

Descending Branch of the MFCA

Question 18

• the profunda femoris artery gives rise to 4 perforating branches; the
  fourth is the termination of the profunda femoris artery
• all branches pass posterolaterally and pierce the adductor magnus muscle near its area of insertion on the femoral shaft
• adductor brevis muscle is the landmark for the first, second and third perforating arteries of profunda femoris artery

Answer 18

Perforating Arteries of Profunda Femoris

Question 19

• arises and passes proximal to the superior border of the adductor brevis m.

Answer 19

First Perforating Artery

Question 20

• arises at and pierces the adductor brevis muscle, usually near the midportion of the muscle belly
• supplies the nutrient artery to the femur

Answer 20

Second Perforating Artery

Question 21

• arises and passes distal to the inferior border of the adductor brevis m.

Answer 21

Third Perforating Artery

Question 22

• the termination of the profunda femoris artery
• located just proximal to the adductor hiatus
• anastomoses with branches of the popliteal artery

Answer 22

Fourth Perforating Artery

Question 23

• a. of the medial femoral compartment; has anterior and posterior branches
• exits the pelvis via the obturator canal
