Study Notes
The Mandible: Overview
- Largest and strongest facial bone.
- Horseshoe-shaped, single bone forming the lower jaw.
- Only movable bone of the skull.
- Articulates with the temporal bone via the temporomandibular joint (TMJ).
- Attachment point for masticatory and other muscles.
Mandible: Main Parts
- Body: Horizontal portion, fused anteriorly forming a U-shape.
- Ramus (Rami - plural): Ascends vertically from the body's posterior aspect; topped by the condyle and coronoid process.
- Coronoid Process (CP): Sharp, beak-like process; temporalis muscle insertion point.
- Condyle (H): Roller-shaped head articulating with the temporal bone's mandibular fossa; supported by the neck (N).
- Alveolar Process (AP): Houses 16 teeth (8 per side); consists of facial (lateral) and lingual (medial) plates joined by bony septa.
External Features of the Mandible
- External Oblique Ridge: Bone ridge originating at the mental tubercle, sweeping upwards and backwards to form the ramus's anterior border.
- Mental Foramen: Located midway between inferior border and alveolar crest (near the second premolar); transmits mental nerve and artery.
- Mental Protuberance (Chin): Triangular bone elevation.
- Mental Tubercles: Small elevations on either side of the mental protuberance.
Internal Features of the Mandible
- Digastric Fossae: Small depressions on either side of the midline; origin of the anterior belly of the digastric muscle.
- Mental Spines (Genial Tubercles): Up to four separate spines or a single fused spine; origin of the genioglossus (upper) and geniohyoid (lower) muscles.
- Mylohyoid Ridge: Attachment origin for the mylohyoid muscle (anterior floor of mouth).
- Submandibular Fossa (SMF): Location of the submandibular salivary gland.
- Sublingual Fossa (SLF): Location of the sublingual salivary gland.
- Mandibular (Inferior Dental) Foramen: Oblique opening midway on the ramus; passage for the inferior dental nerve and artery; covered anteriorly by the lingula.
