    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.  

  • Pubourethral triangle

    A triangular space in the perineum bounded laterally by the ischiocavernous muscle, medially by the bulbocavernous muscle, and posteriorly by the superficial transverse perineus muscle.  

  • Posterior cervical triangle

    The triangular region wrapping around the side of the neck bounded by the upper border of the clavicle, the posterior border of the sternocleidomastoid muscle, and the anterior border of the trapezius muscle.  

  • Triangle of petit

    The space above the hip bone between the exterior oblique muscle, the latissimus dorsi, and the interior oblique muscle.  

  • Occipital triangle of the neck

    The triangle bounded by the sternocleidomastoid, the trapezius, and the omohyoid muscles.  

  • Mylohyoid triangle

    The triangular space formed by the mylohyoid muscle and the two bellies of the digastric muscle.  

  • Lumbocostoabdominal triangle

    The triangle bounded in front by the obliquus abdominis extemus, above by the lower border of the serratus posterior inferior and the point of the 12th rib, behind by the outer edge of the erector spinae, and below by the obliquus abdominis internus.  

  • Inferior carotid triangle

    The triangular space bounded by the middle line of the neck, the sternomastoid muscle, and the anterior belly of the omohyoid muscle.  

  • Frontal triangle

    The triangle bounded by the maximum frontal diameter and the lines joining its extremities and the glabella.  

  • Facial triangle

    The triangle bounded by the lines uniting the basion and the alveolar and nasal points, and one uniting the nasal and basion.
