29
Contents of femoral triangle NAVEL
Femoral Nerve Femoral Artery Femoral Vein Empty space Lymphatics
30
Why is empty space important in femoral triangle
To accommodate the increased size of the femoral vessels
31
What is the femoral sheath?
A fibrous tunnel, deep to inguinal ligament
32
3 compartments of femoral sheath
