The mylohyoid line is a bony ridge on the inner surface of the mandible. There are several synonyms for this anatomical feature based on location and function. The submandibular ridge is the portion of the mandible below the mylohyoid line, while the suprahyoid ridge is the portion above it. The mylohyoid groove is a shallow groove that runs parallel to the mylohyoid line and marks the attachment of the mylohyoid muscle. The geniohyoid tubercle is a small bump on the inner surface of the mandible near the midline, which serves as the attachment point for the geniohyoid muscle. These synonyms for the mylohyoid line are important for accurately describing the anatomy of the mandible and surrounding structures.
