Study Notes
Mylohyoid Ridge
- Origin of attachment for the mylohyoid muscle, contributing to the floor of the anterior part of the mouth.
Submandibular Fossa (SMF) & Sublingual Fossa (SLF)
- Submandibular fossa: Site of the submandibular salivary gland.
- Sublingual fossa: Location for the sublingual salivary gland.
Mandibular Foramen
- Positioned at the midpoint of the ramus of the mandible with a slanted/oblique opening.
- Serves as a passage for the inferior dental nerve and artery.
Features of the Mandible
- Forms the lower jaw; a single, horseshoe-shaped bone recognized as the largest and strongest bone of the face.
- Comprised of a horizontal body and two rami (right and left), it is the only movable bone in the skull.
- Articulates with the temporal bone through the temporomandibular joint (TMJ).
Key Parts of the Mandible
- Body: The horizontal portion, fused midline, U-shaped.
- Ramus: Vertical components on either side of the body, containing the condyle and coronoid process.
- Coronoid Process: Sharp, beak-like structure for the temporalis muscle insertion.
- Condyle: Roller-shaped process articulating with the mandibular fossa of the temporal bone.
- Alveolar Process: Houses eight teeth on each side, made of two bone plates—facial and lingual.
External Features
- External Oblique Ridge: Ridge originating from the mental tubercle, sweeping upward to the ramus.
- Mental Foramen: Located at the midpoint of the inferior border; transmits the mental nerve and artery.
- Mental Protuberance: Triangular bone elevation known as the chin, flanked by mental tubercles.
Internal Features
- Digastric Fossae: Depressions marking bony origins for the anterior belly of the digastric muscle.
- Mental Spine (Genial Tubercles): Can have up to four spines; upper aspect serves as the origin for the genioglossus muscle and the lower aspect for the geniohyoid muscle.
