1570s, from Middle French larynx (16c.), from Modern Latin, from Greek larynx (genitive laryngos) "the upper windpipe," probably from laimos "throat," influenced by pharynx "throat, windpipe."
larynx lar·ynx (lār'ĭngks)
n. pl. lar·ynx·es or la·ryn·ges (lə-rĭn'jēz)
The part of the respiratory tract between the pharynx and the trachea, having walls of cartilage and muscle and containing the vocal cords enveloped in folds of mucous membrane.
Plural larynges (lə-rĭn'jēz) or larynxes
The upper part of the trachea in most vertebrate animals, containing the vocal cords. The walls of the larynx are made of cartilage. Sound is produced by air passing through the larynx on the way to the lungs, causing the walls of the larynx to vibrate. The pitch of the sound that is produced can be altered by the pull of muscles, which changes the tension of the vocal cords. Also called voice box.
