| Anatomical terminology | |
In anatomy, the endolymphatic sac is a structure in the inner ear. It is a canal that comes out of the posterior wall of the saccule, then is joined by the utriculosaccular duct, and then passes along the vestibular aqueduct, before it ends up at the endolymphatic sac on the posterior surface of the petrous portion of the temporal bone, where it is in contact with the dura mater.
Disorders of the endolymphatic duct include Meniere's Disease and enlarged vestibular aqueduct.
