GA 1 Femoral triangle

Question 1

What are the boundaries of the femoral triangle?

Answer 1

Floor: Pectineus and iliopsoas muscles

Roof: fascia Lata

Base: inguinal ligament

Lateral wall: Sartorius

Medial wall: adductor longus

Question 2

What are the contents of the femoral triangle?

Answer 2

NAVEL towards the navel

• Femoral Nerve
• Femoral Artery
• femoral Vein
• femoral canal (Empty space) with deep inguinal Lymph nodes

Question 3

Boundaries (description of location)

(femoral triangle)

Answer 3

Subfascial space

triangular depression

superomedial 1/3 thigh

Question 4

Femoral sheath

Answer 4

funnel-shaped fascial tube (prolongation of transversalis fascia)

encloses proximal parts of femoral vessels and femoral canal. (allows femoral vessels to glide smoothly deep to ingiunal ligament)

ends 4-10 cm distal to inguinal L.

Question 5

What are the three femoral sheaths and what’s in them?

are any outside of them?

Answer 5

Question 6

femoral canal

Answer 6

• part of femoral sheath
• contains a few lymph vessesl, loose CT and fat
• allows femoral vein to expand during increased venous return
• extends distally to saphenous opening
• proximal opening 1 cm wide (femoral ring)

Question 7

Femoral ring

Answer 7

small opening covered by parietal peritoneum (1 cm wide)

(proximal opening to femoral canal)

Question 8

Femoral Hernia?

Answer 8

Question 9

Direct vs indirect ingiunal herniae?

???????

Question 10

Inguinal lymph nodes location and drain?

Answer 10

Question 11

Superficial inguinal lymph nodes

Answer 11

Question 12

Deep inguinal lymph nodes

Answer 12

Question 13

Femoral nerve spinal roots?

Answer 13

L2-L4

Question 14

Femoral nerve supplies what muscles?

Answer 14

anterior thigh muscles, and hip and knee joints

• Iliacus
• Sartorius
• Quadriceps femoris
• Pectineus

Question 15

What is the largest branch of lumbar plexus?

Answer 15

Femoral nerve

Question 16

Where does the femoral nerve start and end?

Answer 16

forms in abdomen within psoas major

enters thigh just lateral to midpoint of inguinal L.

later to femoral vessels.

Question 17

what is a part of the saphenous nerve?

Answer 17

terminal cutaneous branch

Question 18

What innervates 1-7?

Answer 18

Question 19

Which map is this and what causes this particular pattern?

Answer 19

Dermatomes

Limb rotation more lumbar contributions visible anteriorly and sacral posteriorly

Question 20

What can an Anterior hip dislocation affect?

Answer 20

femoral nerve and lateral femoral cutaneous nerve

Question 21

What is meralgia paresthetica

Answer 21

Compression of lateral femoral cutaneous nerve as it passes under inguinal ligament causes pain/numbness along lateral thigh

Question 22

Saphenous nerve

Answer 22

Question 23

Adductor canal starts and ends?

Answer 23

begins and femoral triangle apex

ends at adductor hiatus

Question 24

adductor canal contents?

Answer 24

Question 25

Where is the adductor hiatus and what happens here?

Answer 25

opening in tendon of adductor magnus

femoral vessels reach popliteal fossa (posterior knee and leg) via this arch way

Question 26

Femoral artery location from entry to exit?

Answer 26

Question 27

Cannulation of femoral vessels?

Answer 27

Question 28

Where does the profunda femoris a. descend?

what does it give rise to?

Answer 28

• behind adductor longus

In femoral triangle it gives rise to medial and lateral circumflex femoral arteries

Question 29

What are the branches off of profunda femoris called?

Answer 29

Question 30

Medial circumflex femoral artery

Answer 30

Question 31

Lateral circumflex femoral arteries?

Answer 31

Question 32

lateral circumflex femoral named branches?

Answer 32

Question 33

What supply adductors and hamstring muscles? (arterial)

Answer 33

Question 34

femoral vein location?

Answer 34

enters triangle medial to femoral artery

lies deep to femoral artery toward femoral triangle apex

Question 35

What is the clinical significance of the great saphenous vein?

Answer 35
