1

What is the name of the deep fascia of the leg which covers the thigh and gluteal muscles?

What does this aid in?

Fascia Lata

Venous Return

2

The femoral neurovascular bundle travels beneath what structure?

The inguinal ligament

3

From laterally to medial, name the structures the pass through the inguinal ligament.

Femoral Nerve
Femoral Artery
Femoral Vein
Inguinal Lymph Nodes

(Remember NAVL)

4

The ________ vein quickly branches off the femoral vein and passes through the _______ canal

Saphenous

Femoral

5

What are the THREE main nerves of the lower extremity?

From which plexus do they originate?

Obturator (Lumbar Plexus)

Femoral (Lumbar Plexus)

Sciatic (Sacral Plexus)

6

T/F: All motor and almost all sensory BELOW THE KNEE in innervated by branches of the femoral nerve

False

It is innervated by the sciatic nerve

7

The femoral nerve is a branch of the ________ plexus and supplies the _________ compartment of the thigh.

Which lumbar vertebrae is this derived from?

Lumbar Plexus

Anterior Compartment

L2, L3, L4

8

The sciatic nerve is derived from the ________ plexus and will supply the __________ compartment of the thigh and lower leg

Lumbosacral Plexus

Posterior Compartment

9

What are the 'roots' of the lumbosacral plexus?

L4
L5
S1
S2
S3
S4

10

The gluteal and sub-gluteal muscles are innervated by branches of the _______ plexus

Sacral

11

T/F: External genitalia are innervated by the lumbar plexus?

False

They are innervated by the sacral plexus

12

Which fibers of the sacral plexus compose the pudendal Nerve?

S2, S3, S4

Remember.... "S2, S3, S4 keep you pudendum off the floor"

13

Holding the hips in flexion for and extended period of time could injury what nerves?

Femoral Nerve
Obturator Nerve

14

Applying deep lateral lower leg pressure for an extended period of time could injury which nerve of the lower leg?

Common Fibular Nerve

15

Which branch of the common illiacs supplies the gluteal and subgluteal muscles?

Internal Illiac

16

Which branch of the common illiacs supplies blood to the legs?

External illiac

17

Which TWO branches of the posterior internal illiac supply the gluteal muscles?

Superior gluteal artery
Inferior gluteal artery

18

Which branch of the anterior internal illiac supplies the perinuem and the external gentilia?

Internal Pudenal Artery

19

Which branch of the anterior interior illiac supplies the adductor muscles?

Obturator Artery

20

The external illiac artery becomes the _______ artery once it passes through the ________ ligament

Femoral Artery

Inguinal Ligament

21

Which branches of the femoral artery supply the head and neck of the femur?

Medial Femoral Artery
Lateral Femoral Circumflex

22

Which branch of the femoral artery supplies the adductors, hamstrings, and quadriceps?

Deep Femoral Artery

23

As the femoral artery continues to travel inferiorly down the leg, it will eventually become what artery?

The Popliteal Artery

24

The popliteal artery will give off what branches, which supply the knee?

Geniculars

25

As the popliteal artery travels inferiorly it will split into what TWO arteries?

Where and what do each of these supply?

Anterior Tibal Artery
- Anterior Leg muscles

Posterior Tibal Artery
- Flexor Muscles, arch of the feet

26

The obturator artery travels through which foramen of the pelvis?

Obturator Foramen

27

T/F: The obturator artery supplies blood to the femoral head

True

What may happen to the femoral if its blood supply is compromised?

What are causes of this?

Avascular Necrosis

Femoral Neck Fx (Trauma)
Radiation & Chemotherapy
Steroid Use
Alcohol Abuse

29

The great saphenous vein empties into the _________ vein and the small saphenous vein empties into the _________ vein

Great saphenous vein empties into the femoral vein

Small saphenous vein empties into the popliteal vein

30

Is the femoral vein a deep or superficial vein?

Saphenous vein?

Femoral Vein: Depp

Saphenous Vein: Superficial
