femoral traingle, adductor canal, vessels, nerves ant med thigh

Question 1

boundaries of femoral triangle

Answer 1

1. superior- inguinal ligament
2. medial- lateral border adductor longus
3. lateral- medial border of sartorial
4. roof- fascia lata
5. floor- pectinous, illopsoas

Question 2

contents femoral triangle

Answer 2

NAVL

1. femoral nerves as divides into cutaneous and motor branches
2. femoral artery with branches
3. femoral vein
4. lymphatics

Question 3

femoral sheath

Answer 3

• contain femoral artery and vein
• prolongation of transversals fascia from abdomen
• *femoral nerve is not located within sheath

Question 4

femoral canal

Answer 4

• medial to femoral vein
• 3rd partitioned area
• location of deep inguinal lymph nodes
• entrance of canal is femoral ring
• **fat or guts can protrude through there (femoral hernia)

Question 5

femoral nerve location

Answer 5

• courses in groove where illiacus and psoas major muscles join

Question 6

adductor canal boundaries

Answer 6

anteromedially- sartorius (roof) and vasoadductor membrane
anterolaterally- vastus medialis
posteriorly- adductor longus superiorly and adductor magnus inferiorly

Question 7

content of adductor canal

Answer 7

1. femoral artery
2. femoral vein
3. motor nerve to vastus medialis (from femoral nerve)
4. saphenous nerve (femoral nerve)

Question 8

branches of femoral artery

Answer 8

1. superficial circumflex iliac
2. superficial epigastric
3. superficial external pudendal
4. deep external pudendal
5. profunda femoral artery
6. descending genicular

Question 9

branches of profunda femoral artery

Answer 9

1. lateral femoral circumflex
2. medial femoral circumflex
3. perforating arteries (1-4)

Question 10

branches of lateral femoral circumflex

Answer 10

1. ascending
2. transverse
3. descending

Question 11

branches of descending genicular artery

Answer 11

1. articular branches

2. saphenous branchs

Question 12

cruciate anastomosis

Answer 12

1. transverse branch of lateral femoral circumflex
2. medial femoral circumflex
3. 1st perforating artery

Question 13

genicular anastomosis

Answer 13

1. descending branch of lateral femoral circumflex

2. articular branch of descending genicular artery

Question 14

femoral vein

Answer 14

• continuation of popliteal vein above adductor hiatus

- receives tributaries from vena comitantes from femoral artery and greater spahenous vein in femoral triangle

Question 15

popliteal fossa boundaries

Answer 15

superolateral- tendon of biceps femurs
superomedial- semimembranous and semitendinosus
inferolateral- lateral head gastrocnemius
inferomedial- medial head gastrocnemius
roof- popliteal fascia of fascia lata
floor- posterior surface of capsule of knee and popliteus muscle

Question 16

contents of popliteal fossa

Answer 16

1. termination of posterior femoral cutaneous nerve
2. division sciatic nerve into tibial and common fibular components
3. muscular and cutaneous branches of tibial nerve
4. cutaneous branches of common fibular nerve
5. popiteal vein and tributaries
6. popliteal artery and branches
7. popliteal lymph nodes, lymphatic vessels and fat
