large, leaf shaped piece of elastic cartilage that is covered with epithelium. |
epiglottis |
|
Ring of hyaline cartilage that forms the inferior wall of the larynx. |
Cricoid cartilage |
|
triangular pieces of mostly hyaline cartilage located at the posterior, superior border of the cricoid cartilage. |
arytenoid cartilages |
|
horn-shaped pieces of elastic cartilage, are located at the apex of each arytenoid cartilage. |
Corniculate cartilages |
|
club-shaped elastic cartilages anterior to the corniculate cartilages, support the vocal folds and lateral aspects of the epiglottis. |
Cuneiform cartilages |
