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.
Scarpa's belief that the fascia stops hernias from forming is not thought to be true today. Some anatomists suggest the membranous superficial fascia is the scaffold which attaches the skin to the deeper structures so that the skin does not sag with gravity but still stretches as the body flexes or changes shape with exercise.

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.
In front, it is continuous with the dartos fascia of the penis and Scarpa's fascia upon the anterior wall of the abdomen; . On either side it is firmly attached to the margins of the rami of the pubis and ischium, lateral to the crus penis and as far back as the tuberosity of the ischium.
