Femoral triangle

The femoral triangle is a depressed area of the thigh lying distal to the inguinal fold. Its apex is distal, its limits are the medial margin of sartorius laterally, the medial margin of adductor longus medially and the inguinal ligament proximally (the base). Its floor is provided laterally by iliacus and psoas major, medially by pectineus and adductor longus. The femoral vessels, passing from midbase to apex, are in the deepest part of the triangle. Lateral to the artery the femoral nerve divides. The triangle also contains fat and lymph nodes. 

The femoral triangle is an area in the inguinal region that is shaped like an upside-down triangle. The femoral triangle contains the femoral nerve, artery, and vein, and the lymphatics. The femoral triangle is an area in the inguinal region that is shaped like an upside-down triangle and is bordered by the sartorius muscle, adductor longus muscle and inguinal ligament.

1. Femoral nerve: Originates as a branch of the lumbar plexus. The femoral nerve is not contained within the femoral sheath.

2. Femoral artery: Continuation of the external iliac artery. The femoral artery is located midway between the anterior superior iliac spine and the pubic symphysis.

3. Femoral vein: Continues as the external iliac vein.

4. Lymphatics.
