Across
- 2. Only abductor of the vocal folds; Attached to the posterior lamina of the cricoid and the muscular process of the arytenoid; Pulls the muscular process of arytenoids posteriorly and medially, redirecting the vocal processes laterally to abduct (draw apart) the vocal folds; Abducts fully for respiration and partially for voiceless sounds
- 5. Thick, strong, ring-shaped, and taller posteriorly;Forms the lower and posterior parts of the wall of the larynx;articulates with the thyroid and arytenoid cartilages
- 6. have an attachment outside the larynx
- 13. nerve that innervates the larynx
- 15. helps with movement during swallowing; round elastic cord, which forms the posterior border of the thyrohyoid membrane and passes between the tip of the superior cornu of the thyroid cartilage and the extremity of the greater cornu of the hyoid bone
- 16. semicircular bone that the larynx is suspended from;serves as a major muscular attachment for many extrinsic muscles of the larynx
- 18. Attached to the anterior muscular process and superior border of the cricoid; Moves muscular process anterolaterally, making the vocal process move medially
- 19. superior to the true vocal folds;not normally active during speech but may be active during effortful speech or vegetative closure (coughing/ clearing, defecating, heavy lifting, bearing down)
- 20. leaf shaped carilage attached to interior of the cricoid cartilage;By directing food/liquid around the airway, the ______ helps protect the airway!
- 22. connects larynx to lungs; windpipe
- 23. arytenoid cartilages articulate with the posterior lamina of the cricoid cartilage at this location
- 24. sudden pressure drop at the level of the vocal folds results in a suction
Down
- 1. inferior to the false vocal folds; sound source for phonation
- 3. muscle attachments within the larynx
- 4. made up of two laminae (plates) that fuse anteriorly to form the laryngeal prominence/ thyroid notch (Adam’s apple); plays a role in the production of the human voice, providing protection and support for the vocal folds
- 7. Attaches the left and right arytenoid cartilages;2 Bellies: Transverse and Oblique; Pulls arytenoids together, causing tighter closure of the vocal folds, especially posteriorly
- 8. a ligament in the neck; It connects the cricoid cartilage to the thyroid cartilage; prevents these cartilages from moving too far apart
- 9. joint that allows for movement;cornu (horns) articulate with the sides of the cricoid cartilage and form this joint
- 10. Attach to anterior arch of cricoid and anterior rim of thyroid; 2 Bellies: Pars recta and Pars oblique; Rocks the thyroid over the cricoid. Since the vocal folds are attached to the interior angle of the thyroid, this action stretches and thins the vocal folds, increasing pitch
- 11. connects the cricoid cartilage with the first ring of the trachea
- 12. Sit on top of the arytenoids (at the apex);anchor for the suprahyoid and infrahyoid
- 14. Small cartilages that sit superiorly to the corniculates; Completely embedded within the aryepiglottic fold; Unclear purpose- may serve to provide additional stability to the laryngeal complex
- 17. Paired, pyramid-shaped cartilages that articulate with the posterior lamina (plates) of the cricoid cartilage at the cricoarytenoid joint;allows rocking and sliding motion
- 21. the voice box that houses the vocal folds
