Flashcards in Test 05.45.Thigh 1 Deck (18):
1

1. How is the femur directed?

Inferomedially

2

2. The femur is about how much a person’s height?

¼

3

3. How does the head of the proximal epiphysis project?

Superomedially and slightly anteriorly

4

4. What is the angle of inclination? How does the angle correlate with age and sex?

Angle of inclination is the angle which the head connects to the shaft through the neck
Angle is widest at birth then decreases with age (narrowest in old age)
Angle less in females because female have wider hips

5

5. Draw and label the following:
Greater and lesser trochanters
Intertrochanteric line anteriorly
intertrochanteric crest posteriorly
linea aspera
Medial and lateral epicondyles
Medial and lateral condyles
Intercondylar fossa
Popliteal surface

6. The superficial fascia is continuous with what? What does it contain a lot of?

Continuous with abdominal fascia
Fat

7

7. What are the nerves that are embedded in the superficial fascia of the thigh? Give levels

Subcostal (T12)
Iliohypogastric (T12, L1)
Ilioinguinal (L1)
Genital Femoral (L1, L2)
Genital branch
Femoral branch
Lateral Femoral Cutaneous (L2, L3)
Femoral (L2, L3, L4)
Lumbosacral Trunk (L4, L5)

Accessory obturator (L3, L4)
Obturator (L2, L3, L4)

8

8. Give five cutaneous nerves of the superficial fascia

Genital branches of genital femoral and ilioinguinal nerves
Femoral branch of genitofemoral
Medial cutaneous branch of femoral
Intermediate cutaneous branch of femoral
Lateral femoral cutaneous nerve

9

9. Where do the genital branches of the genitofemoral and ilioinguinal nerves emerge from? To supply what? Levels?

Come from superficial ring to supply proximal medial thigh
Most of the branches go to genital region

Levels: Genital branches of the genitofemoral (L1,L2) and ilioinguinal (L1) nerves

10

10. What does the femoral branch of the genitofemoral nerve supply? Levels?

Skin over the femoral triangle (proximal part of anterior thigh)
(L1, L2)

11

11. What the medial cutaneous branch of femoral nerve supply?

Skin of medial thigh

12

12. What does the intermediate cutaneous branch of femoral nerve supply?

Skin of distal anterior thigh

13

13. Where does the Lateral femoral cutaneous nerve nerve enter? Supplies? Levels?

Enters the thigh medial to ASIS
Supplies lateral thigh, lateral to the intermediate cutaneous branch of the femoral nerve
(L2,L3)

14

14. What does the posterior femoral cutaneous nerve supply?
Originates from?
What is its course?
Levels?

Supplies posterior thigh and popliteal region
Originates from sacral plexus
Courses inferiorly into the thigh from the gluteal region
(S1, S2, S3)

15

16. What branches does the proximal part of the femoral artery provide?

Superficial epigastric artery
Superficial circumflex iliac artery
Superficial external pudendal artery
Deep external pudendal artery

16

17. What area does the superficial epigastric artery supply?

Goes superiorly to supply skin over the lower abdominal wall

17

18. How does the superficial circumflex iliac artery proceed? What does its path parallel?

Proceeds laterally inferior to the inguinal ligament
Parallels course of the deep circumflex artery

18

19. Where does the great saphenous vein begin and end?
Located in what fascia?
What is a remarkable feature of this vein?
How does it enter the thigh?
Transverse what opening to empty into?

1. Great saphenous v

• Begins in the foot and ascends to its termination at the proximal part of the thigh

• Located in the superficial fascia

• Has valves; more numerous in the leg

• Enters the thigh by passing posterior to the medial condyle of the femur

• Traverses the saphenous opening in the fascia lata to empty into the femoral vein
