This document discusses the anatomy of the anterior region of the neck, including the subhyoid bursa, thyroid and cricoid cartilages, anterior triangle boundaries defined by the digastric and omohyoid muscles, subdivisions within the triangle, and the suprahyoid and infrahyoid regions containing specific muscles like the digastric, stylohyoid, mylohyoid, and geniohyoid. It concludes with some notes on applied anatomy like anterior midline swellings and procedures like tracheostomy.
