The anterior cervical triangle (Cervical triangle I) is an unpaired thyroid triangle located on the anterior surface of the neck. The base of the triangle is directed from the manubrium of the sternum downward, the lateral side is directed towards the medial surface of the sternocleidomastoid muscle, and the apex is directed upward and back, to the base of the skull.

The superficial formations located in the anterior region of the neck include the superior laryngeal nerve, blood vessels and the annular muscle. The deep structures of this area include the following formations: peripharyngeal ring. Esophagus, windpipe, thyroid gland. Glossopharyngeal nerve, upper cervix and parotid salivary gland, internal jugular vein and laryngeal vessels.
