fem·o·ral tri·an·gle

[TA]
a triangular space at the upper part of the thigh, bounded by the sartorius and adductor longus muscles and the inguinal ligament, with a floor formed laterally by the iliopsoas muscle and medially by the pectineus muscle; the branches of the femoral nerve are distributed within the femoral triangle; it is bisected by the femoral vessels, which enter the adductor canal at the triangles apex.

femoral triangle

a wedge-shaped depression formed by the muscles in the upper thigh at the junction between the anterior abdominal wall and the lower limb through which the femoral nerve, artery, and vein and lymphatic vessels pass.

femoral triangle

inverted triangular-shaped area at anterior aspect of upper thigh; bounded proximally by inguinal ligament, laterally by medial border of sartorius, medially by medial border of adductor longus; it contains (from superior to deep) skin and superficial fascia, lymphatic vessels and nodes, upper part of the great saphenous vein, femoral branch of genitofemoral nerve, branches of ilioinguinal nerve, femoral vessels and muscle tissue (adductor longus, pectineus, psoas major, iliacus)

triangle

a three-cornered object, figure or area, as such an area on the surface of the body capable of fairly precise definition. Called also trigone.

facial triangle
a triangular area whose points are the basion and the alveolar and nasal points.
femoral triangle
