Lower Limb

Question 1

2.Profunda femoris vein
3.Medial and lateral circumflex femoral vein
4.deep external pudendal vein
5. Direct muscular tributes

Question 3

Largest muscle in extensor compartment of thigh

Answer 3

Quadriceps femoris

Question 4

Course of the femoral vein

Answer 4

Begins :lower end of adductor canal
Ascends in adductor canal
Enter femoral triangle
Transverse the intermediate compartment of femoral sheath
Continues as external iliac vein behind the inguinal ligament medial to the midinguial point

Question 5

Longest cutaneous nerve in the body

Answer 5

Saphenous nerve

Question 6

How does the femoral artery enter the femoral triangle

Answer 6

Behind the inguinal ligament at midinguinal point

Question 7

Course of femoral artery

Answer 7

Runs downward and medially successively thro the femoral triangle and adductor canal
At lower end of adductor canal
Leaves the thigh thro the adductor hiatus ( a tendinous opening in the adductor magnus )
To enter popliteal fossa where it continues as the popliteal artery

Question 8

Femoral artery branch of

Answer 8

External iliac artery

Question 9

Branches of the femoral artery in the femoral triangle

Answer 9

Three superficial
Three deep branches

Question 10

Branches in the adductor canal

Answer 10

1. Muscular branches
2. Descending genicular artery

Question 11

Three superficial branches of the femoral artery

Answer 11

Superficial epigastric artery
Superficial external pudendal artery
Superficial circumflex iliac artery

Question 12

Three deep branches of femoral artery

Answer 12

Profunda femoris artery
Deep external pudendal artery
Muscular branches

Question 13

Course of deep external pudendal artery

Answer 13

Arises below the sexpa.
Passes medially deep to the spermatic cord or round ligament of uterus

Supplies the scrotum or labium majus

Question 14

Course of descending genicular artery

Answer 14

Leaves canal by descending within substance of vastus medialis
Divides into articular & saphenous branches
Saphenous artery accompanies saphenous nerve ( emerge through roof of adductor canal )

Question 15

Artery compressed against the
femoral head at the midinguinal point to control the
bleeding in the distal part of the limb.

Answer 15

Femoral artery

Question 16

Pulsations of the femoral artery felt in

Answer 16

Femoral triangle

Question 17

where is femoral triangle located

Answer 17

On the front of the upper one third of the thigh
Below the inguinal ligament

Question 18

Boundaries of the inguinal ligament

Answer 18

Lateral : medial border of sartorius
Medial : medial border of adductor longus
Base : inguinal ligament
Apex : formed by meeting point of 2 borders
Floor : gutter shaped and muscular
( medial to lateral )
1.Adductor longus
2.Pectineus
3.Psoas major (tendon )
4.Illiacus
Roof :fascia Lata with saphenous opening
Superficial fascia and it’s contents

Question 19

Contents of the femoral triangle

Answer 19

1.Femoral artery & branches
2.Vein & tributaries
3.Femoral nerve
4.Deep inguinal lymph nodes
5.Lateral cutaneous nerve of thigh
6.Femoral branch of genitofemoral nerve
7. Fibrofatty tissue
8. Femoral sheath

Question 20

Femoral vein and artery relation

Answer 20

Artery passes downward and medially in triangle .
Artery lies lateral to vein at base .
At apex it lies anterior to the vein .

Question 21

Largest branch of the femoral artery

Answer 21

Profunda femoris

Question 22

Where does the profunda femoris arise from

Answer 22

Arises :Lateral side of f.artery
3.5cm below inguinal ligament
Course Spirals medially behind vessels
Gives rise to medial and lateral circumflex artery
Medial circumflex disappears between psoas major and pectineus
Lateral b/w anterior and post divisions of femoral nerve

Question 23

Dex pudendal artery course

Answer 23

Pierces fascia lata
Passes medially behind the spermatic cord

Question 24

Compartments of the femoral sheath
Divided by

Answer 24

Lateral = femoral artery , femoral branch of genito femoral nerve
Intermediate = vein
Medial = small and known as femoral Canal

By anteroposterior septa

Question 25

What is also known as femoral canal

Answer 25

Medial compartment of the femoral sheath

Question 26

What is femoral sheath

Answer 26

Funnel shaped fascial sheath enclosing the upper 3-4 cm of the femoral vessels
