Name the vascular structures that traverse the submandibular triangle

The vascular structures that traverse the submandibular triangle are:

1. Facial artery: This artery arises from the external carotid artery, passes through the submandibular gland, and then loops over the mandible at the anteroinferior edge of the masseter muscle. It supplies blood to the structures of the face.

2. Facial vein: This vein begins near the angle of the eye and runs a course that is generally parallel to the facial artery. It drains blood from the areas of the face that are supplied by the facial artery.

3. Submental artery: This is a branch of the facial artery that runs forward on the mylohyoid muscle and supplies the surrounding muscles and the integument.

4. Submental vein: This vein accompanies the submental artery and drains into the facial vein.

5. Anterior and posterior facial veins: These veins drain the facial structures and empty into the internal jugular vein.

6. Lymphatic vessels: These vessels drain lymph from the facial structures into the submandibular lymph nodes.

The vascular structures that traverse the submandibular triangle are:

1. Facial artery: This artery arises from the external carotid artery, passes through the submandibular gland, and then loops over the inferior border of the mandible at the anterior edge of the masseter muscle. It supplies blood to the structures of the face.

2. Facial vein: This vein begins near the angle of the eye and runs a course that is generally parallel to the facial artery. It also passes through the submandibular triangle.

3. Submental artery: This is a branch of the facial artery that runs forward on the mylohyoid muscle and supplies the surrounding muscles, and the skin and subcutaneous tissue of the chin and lower lip.

4. Submental vein: This vein accompanies the submental artery and drains into the facial vein.

5. Anterior and posterior facial veins: These veins drain the facial structures and pass through the submandibular triangle.

6. Submandibular lymph nodes: These are not vascular structures, but they are important structures that are found in the submandibular triangle. They receive lymph from the surrounding structures.
