Submandibular Triangle

The submandibular triangle is a small area on the front surface of the neck, bounded below by the hyoid bone, behind and on the sides by the corner of the lower jaw. In front of it is the chin bone, with which it can be connected in several places. Also above it is the thoracic triangle - the sternocleidomastoid trunk.

The submandibular triangle contains the following structures:

The submandibular gland (glandula submandibularis) is a glandular organ located in the submandibular canal on the inner surface of the buccal-pharyngeal fascia. It produces a secretion that contains lysozyme, helps destroy bacteria and maintains the health of the oral mucosa. The submandibular canal (canalis pterygoideus major) is a long narrow canal lying between the hyoid and submandibular bones. Inside it pass the sublingual artery and vein, the facial branches of the mandibular and maxillary nerves. The lower jaw (mandibula) is the chewing bone, the part of the lower jaw that articulates with the temporal joint and is connected to the zygomatic arches at the base of the skull. Musculature: subcutaneous muscle of the neck (m. platysma), digastric muscle (m. digastricus) and other lesser-known muscles located in the area. Fat cell



**Submandibular triangle** is the name given to the triangle located below the jaw. It is part of the so-called “neck” of the human body. This triangle contains a large number of muscles, ligaments, vessels and nerves that ensure the normal functioning of the human maxillofacial system.

The submandibular **triangle consists of three muscles**: - Submandibular muscle (m. submandibularis) - Mylohyoid muscle (mm. mylohyoideus) - Anterior abdominal wall (M. frontalis) It also has tendons, vessels and nerves. This triangle also contains the **submandibular tubercle** (tuberculum submandebulare), which is an anatomical landmark for dentistry and osteopathy.

Functions of the submandibular triangle: - Provides movement of the tongue. - Supports jaw function during chewing. - Participates in the formation of speech. - Protects the main arteries and veins of the neck.
