Normal Laryngeal Histology
The seven cartilages are the epiglottis (elastic type), thyroid (hyaline type), cricoid (hyaline type), arytenoid (hyaline type), corniculate (elastic type), cuneiform (elastic type), and triticeous (hyaline type).
Is cricoid cartilage Adam's apple?

Larynx. The epiglottis is elastic cartilage and has fenestrations , which usually contain seromucous glands, and may serve as a conduit for carcinomas to enter the preepiglottic space. The arytenoid cartilages are small hyaline cartilages associated with mucoserous glands and are important in phonation.
