Ciaccio's glands are a tiny glandular structure located in the mucous membrane of the top of the larynx. These glands were first discovered and named by Italian anatomist, Salvatore Ciaccio in 1893. Also known as the glandulae laryngis, these glands play an important role in keeping the larynx moist and lubricated, preventing dryness, and minimizing irritation. Synonyms for Ciaccio's glands include laryngeal glands, laryngeal mucous glands, larynx glands, and glandulae laryngicae. These synonyms are often used interchangeably in medical literature and research papers, where the focus is on the anatomy and function of the larynx.
