Module 2

Question 1

Saphenous Opening

Answer 1

Gap in the fascia lata below medial part of inguinal ligament

Pierced by the great saphenous vein, superficial inguinal ligament, efferent lymphatics from superior inguinal lymph nodes

Question 2

Femoral Triange

Answer 2

Boundaries: Inguinal ligament, sartorious, adductor longus, pectineus, skin & superficial fascia with its contents

Question 3

Contents of the femoral triangle

Answer 3

Femoral artery
Femoral vein
Femoral sheath
Genitofemoral N
Femoral N & Branches
Lateral Cutaneous N 
Deep Inguinal Lymph Node

Question 4

Femoral Sheath

Answer 4

A funnel shaped sheath which descends from the lower part of abdomen to surround upper most 4cm of femoral vessels in femoral triangle

Question 5

Femoral Ring

Answer 5

L: Genitofemoral N & Femoral Artery
I: Femoral Vein
M: Deep Lymph or Nodes of Rosenmuller

Question 6

Function of the femoral sheath

Answer 6

Allow for smooth and easy gliding of the femoral vessels during movement of thigh and hip joint

Question 7

Femoral Canal

Answer 7

Rectangular shaped compartment within femoral triangle

Question 8

Femoral Ring - Boundaries

Answer 8

Inguinal ligament, pectineal ligament, laclunar ligament, femoral vein

Question 9

Superficial Branches of Femoral Artery & Structures they pierce

Answer 9

Superficial epigastric artery - pierces upwards and medially to supply infra-umbilical part of anterior abdominal wall

Superficial Circumflex Iliac Artety - pierces fascia lata laterally to the saphenous opening to supply the vastus lateralis muscle

Superficial external pudendal artery pierces cribiform fascia and passes medially in front of spermatic cord or round ligament of uterus to supply external genital organs

Question 10

Deep External Pudendal Artery

Answer 10

Branch of femoral that passes medially across the pectineus and adductor longus and supplies the external genitalia

Question 11

Deep Profunda Femoris Arty

Answer 11

Largest branch of the femoral artery and follows the femoral artery and branches laterally. Branches - medial and lateral circumflex femoral artery ad 4 perforating arteries

Question 12

Descending Genicular Artery

Answer 12

Originates from the femoral artery and gives off a musculocutaneous and saphenous branch

Question 13

Femoral Vein

- beginning, termination, tributaries & valves

Answer 13

Upward continuation of the popliteal vein through the adductor opening and continues as external iliac vein behind the inguinal ligament, medial to the femoral artery.

Tributaries - profunda vein, medial & lateral circumflex femoral vein, deep pudendal vein, great saphenous vein, muscular vein

Question 14

Femoral Nerve - course and relations

Answer 14

Arises from dorsal divisions of ventral rami of L2-4 and enter the thigh behind the midpoint of the inguinal ligament to the femoral artery outside the femoral sheath between iliacus and psoas major muscle before ending in saphenous nerve

Question 15

Muscular Branches of Femoral N

Answer 15

Iliacus
Pectineus
Vascular branch to femoral A

Int. Cutaneous nerve of thigh
Medial cutaneous N of thigh
N to Sartorious

Question 16

Articular branches of the femoral nerve

Answer 16

N to Sartorious - supplies hip joint
N to Rectus Femoris - supplies hip
N to 3 vastus muscles - supplies knee
