Submandibular Triangle - Divisions - Posterior Part

Posterior Part

The posterior part of this triangle contains the external carotid artery, ascending deeply in the substance of the parotid gland

This vessel lies here in front of, and superficial to, the internal carotid, being crossed by the facial nerve, and gives off in its course the posterior auricular, superficial temporal, and internal maxillary branches: more deeply are the internal carotid, the internal jugular vein, and the vagus nerve, separated from the external carotid by the Styloglossus and Stylopharyngeus, and the hypoglossal nerve
