A triangular space located at the top of the thigh beneath the skin and the fascia lata. The base of the triangle is the inguinal ligament. The medial side is the adductor longus muscle, which meets the lateral side (the sartorius muscle) at the apex of the triangle approx. 4 cm down the thigh. The inside (deep) wall of the femoral triangle is formed by the iliopsoas and pectineus muscles. Running through the femoral triangle are the femoral nerve and the femoral sheath. See: femoral sheath

The triangular region of the neck, bounded by the inferior border of the mandible, the stylohyoid muscle and the posterior belly of the digastric muscle, and the anterior belly of the digastric muscle; it is one of three triangles included in the anterior triangle of the neck. This was formerly called the submaxillary triangle.
A superficial region under the chin with its base being the hyoid bone and its right and left walls being the right and left anterior bellies of the digastric muscle. The front wall of the triangle is skin; the back wall is the outer surface of the mylohyoid muscle.
