How it works
The larynx drawn three times: from the front, from behind, and cut in half down the middle. Eighteen parts to find and name, from the hyoid bone at the top to the trachea below.

Outside: three big cartilages, three small pairs
From the front, top to bottom: hyoid bone, thyrohyoid membrane, thyroid cartilage, cricothyroid ligament, cricoid cartilage, trachea. The epiglottis rises behind the hyoid. From behind, an arytenoid sits on each side of the cricoid, with a corniculate cartilage on its tip and a cuneiform cartilage in the fold above.
Inside: two pairs of folds
The cut shows two ridges on the side wall. The upper is the vestibular fold and the lower is the vocal fold, with the ventricle between them. The space above both is the vestibule.
- Thyroid is the shield, cricoid is the ring: the only cartilage that goes all the way round.
- False above, true below: the vestibular fold sits over the vocal fold.
Questions and answers
What are the nine cartilages of the larynx?
Three single ones, the thyroid, the cricoid and the epiglottis, and three pairs: the arytenoid, corniculate and cuneiform cartilages. The hyoid bone above the larynx is a bone, not one of its cartilages.
What is the difference between true and false vocal cords?
The true vocal cords, or vocal folds, are the lower pair. They move and vibrate to make the voice. The false vocal cords, or vestibular folds, lie just above them and stay still, helping to guard the airway.
What is the Adam's apple?
The laryngeal prominence: the bump at the front of the neck where the two plates of the thyroid cartilage meet. It is usually easier to see in adult men.
Can I use this page to correctly label the features of the larynx?
Yes, for practice. The drawings are our own and not a copy of any textbook figure, so the page is not an answer key: your course figure may show a different view or ask for other names.
