Muscles attached to the lower incisor area / anterior mandible (genial tubercles):
Show answer and explanation
Correct answer: D. Geniohyoid and genioglossus
- A. Incorrect. Palatoglossus is a tongue/palate muscle. Digastric attaches to the lower mandible and hyoid — not the genial tubercles.
- B. Incorrect. Mylohyoid originates from the mylohyoid line — not the genial tubercles. Masseter attaches to the mandibular ramus.
- C. Incorrect. Buccinator and mentalis attach to the lips/cheek — not the anterior mandibular spine.
- D. Correct. The GENIAL TUBERCLES (small bony spines on the inner surface of the anterior mandible, near the midline) serve as attachment points for: GENIOHYOID (superior and inferior tubercles) — pulls the hyoid bone forward, and GENIOGLOSSUS (superior and inferior tubercles) — the main tongue protrusion muscle. Both originate from the genial tubercles (mental spine).
