What is the histological structure of the Eustachian tube?
The Eustachian tube connects the middle ear to the nasopharynx, playing a role in equalizing ear pressure. It is lined by a pseudostratified ciliated columnar epithelium with goblet cells that produce mucus. The submucosa contains seromucous glands, lymphatic tissue, and a cartilaginous skeleton, which provides structural support and helps in the tube's opening and closing mechanism.
