The mylohyoid line is a bony ridge on the internal surface of the body of the mandible. The mylohyoid line extends posterosuperiorly. The mylohyoid line continues as the mylohyoid groove on the internal surface of the ramus. The mylohyoid muscle originates from the anterior (front) part of the mylohyoid line. [1]
The oblique ridge is found on the occlusal surfaces of maxillary molars. It is formed by the union of the distal cusp ridge of the mesiolingual cusp and the triangular ridge of the distobuccal cusp. The oblique ridges usually forms the distal boundary of the central fossa.
The following outline is provided as an overview of and topical guide to human anatomy: . Human anatomy is the scientific study of the morphology of the adult human.It is subdivided into gross anatomy and microscopic anatomy.

The submental space is a fascial space of the head and neck (sometimes also termed fascial spaces or tissue spaces). It is a potential space located between the mylohyoid muscle superiorly, the platysma muscle inferiorly, [1] under the chin in the midline.
Its medial surface forms part of the lateral wall of the nasal cavity; at its upper part is a rough, uneven area, which articulates with the ethmoid, closing in the anterior ethmoidal cells; below this is an oblique ridge, the ethmoidal crest, the posterior end of which articulates with the middle nasal concha, while the anterior part is termed ...
The pterygomandibular raphe (pterygomandibular fold [1] or pterygomandibular ligament) is a thin [2] tendinous band of buccopharyngeal fascia.It is attached superiorly to the pterygoid hamulus of the medial pterygoid plate, and inferiorly to the posterior end of the mylohyoid line of the mandible.
Diagram of medial surface of the mandible, showing the slanting attachment of mylohyoid (the mylohyoid line). This arrangement means that the apices of posterior teeth are more likely to be below the level of mylohyoid, so a periapical abscess associated with posterior teeth is more likely to spread into the submandibular space.
