who identified the tube connecting the ear and throat
Eustachian tube The Eustachian tube /juːˌsteɪ.ʃən/, also known as the auditory tube or pharyngotympanic tube,[1] is a tube that links the nasopharynx to the middle ear. It is a part of the middle ear. In adult humans the Eustachian tube is approximately 35 mm (1.4 in) long and 3 mm (0.12 in) in diameter.[2] It is named after the sixteenth-century anatomist Bartolomeo Eustachi.[3]
Larynx The larynx (/ˈlærɪŋks/; plural larynges; from the Greek λάρυγξ lárynx),[1] commonly called the voice box, is an organ in the neck of tetrapods involved in breathing, sound production, and protecting the trachea against food aspiration. The larynx houses the vocal cords, and manipulates pitch and volume, which is essential for phonation. They are situated just below where the tract of the pharynx splits into the trachea and the esophagus.
