The femoral triangle (or Scarpa's triangle) is an anatomical region of the upper third of the thigh. It is a subfascial space which appears as a triangular depression below the inguinal ligament when the thigh is flexed, abducted and laterally rotated.
The nerve enters Scarpa's triangle by passing beneath the inguinal ligament, just lateral to the femoral artery. In the thigh, the nerve lies in a groove between iliacus muscle and psoas major muscle , outside the femoral sheath , and lateral to the femoral artery.
Medial and inferior to the pubic tubercle, in the male, Scarpa's fascia changes as it continues over the scrotum and forms dartos tunic. This layer is highly infiltrated by elastic and smooth muscle fibers and contains a minimal amount of fat. Scarpa's fascia ends inferior to the inguinal ligament fusing with the fascia lata of the thigh.
It is thinner and more membranous in character than the superficial fascia of Camper, and contains a considerable quantity of orange elastic fibers.. It is loosely connected by areolar tissue to the aponeurosis of the external oblique muscle, but in the midline it is more intimately adherent to the linea alba and the pubic symphysis, and in the male, it is prolonged on to the dorsum of the ...

This structure demarcates the superior border of the femoral triangle. [4] It demarcates the inferior border of the inguinal triangle . The midpoint of the inguinal ligament, halfway between the anterior superior iliac spine and pubic tubercle, is the landmark for the femoral nerve.
In addition to being continuous with itself between the scrotum and the penis, it is also continuous with Colles' fascia of the perineum and Scarpa's fascia of the abdomen. [1] The dartos lies just below the skin, which places it just superficial to the external spermatic fascia in the scrotum and to Buck's fascia in the penile shaft.
Inguinal triangle is labeled in green. Borders: inferior epigastric artery and vein: labeled at center left, and run from upper right to bottom center. inguinal ligament: not labeled on diagram, but runs a similar path to the inguinal aponeurotic falx, labeled at bottom. rectus abdominis muscle: runs from upper left to bottom left.
