| FEMORAL TRIANGLE: |
| Location
and boundaries |
|
|
 Location:
Anteromedial in the upper thigh |
| |
Bounded by:
Superiorly, the inguinal ligament extending
from the anterior superior iliac spine to the pubic tubercle.
Laterally, medial border of sartorius.
Medially, medial border of adductor longus.
Roof (anterior): fascia lata pierced in
the region of saphenous opening to form cribriform fascia.
Floor (posterior): adductor
longus, pectineus, iliopsoas.
Apex continues into the adductor canal.

CONTENTS
OF THE FEMORAL TRIANGLE |
 |
Hover
over the hotspots to show names |
- Femoral vein (C)and its proximal tributaries.
- Femoral artery (B)and its proximal branches.
- Femoral nerve (A) and its branches.
- Inguinal lymph nodes.

FEMORAL SHEATH |
 |
Formed
by fascia transversalis anteriorly and fascia iliaca posteriorly.
Divided into
three compartments by two antero-posterior septa.
- Medial compartment is
called the femoral canal.
- Middle (intermediate)
compartment contains the femoral vein.
- Lateral compartment contains
the femoral artery and femoral branch of genitofemoral nerve.

|
| THE FEMORAL CANAL |
|
Is the medial compartment of the femoral sheath (A)
Allows expansion of the vein e.g. during exercise.
It
contains:
- fat,
- loose connective tissue,
- lymph vessels connecting deep
inguinal to external iliac nodes
- nodes of Cloquet.
Identify the muscles labelled 1 and 2 which form
boundaries of the femoral triangle and the contents labelled A to D
.
