Neurovascular Structures & Relationships in Anteromedial Thigh

Question 1

Describe the retro inguinal space

Answer 1

The retroinguinal space is deep to the inguinal L.
2 compartments: Muscular and vascular
Important passageway that connects the trunk with the lower limb

Question 2

Muscular compartment of retro inguinal space contains:

Answer 2

Iliacus
Psoas major
Femoral N

Question 3

Vascular compartment of retro inguinal space contains:

Answer 3

Femoral A
Femoral V
Femoral canal.
All of these are encapsulated by the femoral sheath.

Question 4

What happens to the Femoral N once it enters the femoral canal

Answer 4

It divides into several branches to the anterior thigh muscles
Sends articular branches to hip and knee joints
Provides several cutaneous branches to anteromedial side of thigh

Question 5

What is the terminal cutaneous branch of the femoral N

Answer 5

The saphenous N.
It descends thru the femoral triangle, acompanies the Femoral A & V thru adductor canal and becomes superficial when it passes thru sartorius and gracilis.

Question 6

What does the saphenous N supply

Answer 6

Skin and fascia on the anteromedial aspect of knee, leg, and foot

Question 7

When the Femoral V pops out of the femoral sheath through the saphenous opening, what is it called?

Answer 7

Great Saphenous V

Question 8

3 compartments of the femoral sheath

Answer 8

Lateral: femoral A
Intermediate: femoral V
Medial: femoral canal

Question 9

What forms the floor of the femoral triangle

Answer 9

Iliopsoas laterally and pectineus medially

Question 10

What forms the roof of the femoral triangle

Answer 10

fascia lata, cribiform fascia, subq tissue, and skin

Question 11

Adductor canal provides an intermuscular passageway for what?

Answer 11

Femoral A & V
Saphenous N
N. to vastus medialis

delivers the femoral vessels to the popliteal fossa where they become popliteal vessels
