where is the eustachian tube located in the ear
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]
Utricle (ear) The utricle, or utriculus (Latin: utriculus, diminutive of uter, meaning "leather bag"), along with the saccule, is one of the two otolith organs located in the vertebrate inner ear. The utricle and the saccule are parts of the balancing apparatus (membranous labyrinth) located within the vestibule of the bony labyrinth (small oval chamber).[1] These use small stones and a viscous fluid to stimulate hair cells to detect motion and orientation. The utricle detects linear accelerations and head-tilts in the horizontal plane.
