Muscles and their function and location
Across
- 7. Origin: sphenoid and lateral pterygoid plate, insertion: condyle, Function: move mandible laterally, protrude mandible, and move condyle forward and down
- 8. Pulls ribs and sternum out and up
- 9. Midline of mandible and travels thru intrinsic muscles, Function: protrude and depress tongue
- 13. Move ribcage down as a unit
- 16. Origin: sternum and clavicle, insertion: mastoid process
- 19. Origin: temporal bone and inferior of parietal, Insertion: top and ramus of mandible, Function: elevate mandible
- 20. Tongue muscle that runs side to side and narrows and elongates the tongue
- 22. Origin: front edge of coxal (hip) bones, Insertion: sternum and 5-7 costal cartilages, Function: lowers ribs and sternum and forces abdominal wall inward
- 23. Origin: inner surface of mandible, Insertion: hyoid, Function: depress mandible
- 24. Origin: hyoid, Insertion: midline raphe
- 26. Elevates and widens the pharynx
- 27. Origin: maxilla and palatine bone, Insertion: angle and ramus, Function: elevate and protrude mandible
- 29. Origin: thyroid and cricoid, Insertion: midline raphe
Down
- 1. Muscles of the tongue that include superior longitudinal, inferior longitudinal, vertical, and transverse
- 2. Tongue muscle that goes back to front and pulls tip and sides of tongue up + shortens tongue
- 3. Move ribcage up as a unit
- 4. Midline of soft palate and sides of tongue, Function: elevate posterior part of the tongue
- 5. Muscles of the tongue that include styloglossus, palatoglossus, hyoglossus, and genioglossus
- 6. From the styloid process of the temporal bone to the sides of the tongue, Function: retracts tongue
- 10. Origin: upper surface of coxal (hip) bones and costal cartilages, Insertion: abdominal aponeurosis, Function: pulls front and side abdominal wall inward
- 11. Origin: zygomatic arch, Insertion: angle and ramus of mandible, Function: elevate mandible
- 12. Same origin, insertion, and function as mylohyoid but innervated by C1
- 14. Pull lower ribs down and force abdominal wall inward
- 15. Origin: ribs 2-5, Insertion: scapula, Function: elevates ribs
- 17. Origin: hamulus (hooks) and mandible, Insertion: midline raphe
- 18. Tongue muscle that runs from oral surface to mandibular surface and flattens/broadens the tongue
- 21. Hyoid and sides of posterior portion of tongue, Function: depress and retract tongue
- 25. Origin: lower border of mandible, Insertion: hyoid bone tendon, Function: depress mandible
- 28. Tongue muscle that goes back to front and pulls tip of tongue down + shortens tongue
