1

What is the main Artery of the Lower Limb?

The Femoral Artery

2

What is the Femoral Artery a continuation of?

The External Iliac Artery

3

When does the External Iliac Artery become the Femoral Artery?

When it crosses under the Inguinal Ligament, into the Femoral Triangle

4

In the Femoral Triangle, which Artery arises from the Posterolateral aspect of the Femoral Artery?

The Profunda Femoris Artery

5

Where does the Profunda Femoris Artery travel?

Posteriorly and Distally

6

What 3 branches come off of the Profunda Femoris Artery?

1. Perforating Branches
2. Lateral Femoral Circumflex Artery
3. Medial Femoral Circumflex Artery

7

How many Perforating Branches of the Profunda Femoris Artery are there?

3 or 4

8

What do the Perforating Branches of the Profunda Femoris Artery perforate?

The Adductor Magnus

9

After perforating the Adductor Magnus, what do the Perforating Branches of the Profunda Femoris Artery contribute to supplying?

1. The Muscles of the Medial Thigh
2. The Muscles of the Posterior Thigh

10

Where does the Lateral Femoral Circumflex Artery travel?

It Wraps around the Anterior, Lateral Side of the Femur

11

What does the Lateral Femoral Circumflex Artery supply?

Some of the Muscles on the Lateral aspect of the Thigh

12

Where does the Medial Femoral Circumflex Artery travel?

It Wraps around the Posterior Side of the Femur

13

What does the Medial Femoral Circumflex Artery supply?

The Head and Neck of the Femur

14

What is the Clinical Significance of the Medial Femoral Circumflex Artery?

In a Femoral Neck Fracture, this Artery can be easily damaged, and Avascular Necrosis can occur

15

What happens to the Femoral Artery after the Profunda Femoris Artery breaks off from it?

It continues and leaves the Femoral Triangle

16

Where does the Femoral Artery travel, after it has left the Femoral Triangle?

Down the Anterior Surface of the Thigh

17

What is the name of the Tunnel which the Femoral Artery travels via, down the Anterior Surface of the Thigh?

Adductor Canal

18

What does the Femoral Artery supply as it travels down the Anterior Thigh?

The Anterior Muscles of the Thigh

19

Where does the Adductor Canal end?

At the Adductor Hiatus

20

What is the Adductor Hiatus?

An opening in the Adductor Magnus

21

What happens to the Femoral Artery as it reaches the Adductor Hiatus?

It moves through this opening

22

What happens to the Femoral Artery after it leaves the Adductor Hiatus?

It enters into the Posterior Compartment of the Thigh, Proximal to the Knee Joint

23

What is the Femoral Artery known as, from when it leaves the Adductor Hiatus?

The Popliteal Artery

24

What is the Clinical Significance of the Femoral Artery being Superficial?

It is a site of easy access and can be used for a variety of procedures, e.g. Coronary Angiography

25

Other than the Femoral Artery, which Arteries supply the Thigh?

1. Obturator Artery
2. Superior Gluteal Artery
3. Inferior Gluteal Artery

26

Where does the Obturator Artery arise from?

The Internal Iliac Artery

27

In which Region does the Obturator Artery arise?

The Pelvic Region

28

Where does the Obturator Artery travel?

Via the Obturator Canal, to the Medial Thigh

29

As the Obturator Artery enters into the Medial Thigh, what happens to it?

It bifurcates into 2 Branches of the Artery

30

What are the 2 Branches the Obturator Artery bifurcates into?

1. Anterior Branch of the Obturator Artery
2. Posterior Branch of the Obturator Artery
