It contains the submandibular gland (salivary), and lymph nodes. The facial artery and vein also pass through this area. The boundaries of the submandibular triangle are: Superiorly – body of the mandible. Anteriorly – anterior belly of the digastric muscle. Posteriorly – posterior belly of the digastric muscle. Carotid Triangle The carotid triangle of the neck has the following boundaries: Superior – posterior belly of the digastric muscle. Lateral – medial border of the sternocleidomastoid muscle. Inferior – superior belly of the omohyoid muscle. The main contents of the carotid triangle are the common carotid artery (which bifurcates within the carotid triangle into the external and internal carotid arteries), the internal jugular vein, and the hypoglossal and vagus nerves . Submental Triangle The submental triangle in the neck is situated underneath the chin. It contains the submental lymph nodes, which filter lymph draining from the floor of the mouth and parts of the tongue. It is bounded: Inferiorly – hyoid bone. Medially – midline of the neck. Laterally – anterior belly of the digastric Muscular Triangle The muscular triangle is situated more inferiorly than the subdivisions. It is a slightly ‘dubious’ triangle, in reality having four boundaries. The muscular triangle contains some muscles and organs – the infrahyoidmuscles, the pharynx, and the thyroid, parathyroid glands. The boundaries of the muscular triangle are: Superiorly – hyoid bone. Medially – imaginary midline of the neck. Supero-laterally – superior belly of the omohyoid muscle. Infero-laterally – inferior portion of the sternocleidomastoid muscle. 🔊Music: Royalty Free Music from Bensound www.bensound.com
