Preferred Label : endolymphatic sac;
Uberon definition : From the posterior wall of the saccule a canal, the ductus endolymphaticus, is given
off; this duct is joined by the ductus utriculosaccularis, and then passes along the
aquaeductus vestibuli and ends in a blind pouch, the endolymphatic sac, on the posterior
surface of the petrous portion of the temporal bone, where it is in contact with the
dura mater. Studies suggest that the endolymphatic duct and endolymphatic sac perform
both absorptive and secretory, as well as phagocytic and immunodefensive,functions
. [WP,unvetted].;
Uberon synonym : saccus endolymphaticus;
Uberon Homology note : Many adult anamniotes have an endolymphatic duct that opens onto the surface of the
head. In other vertebrates, it either is lost or forms a small, deeply seated endolymphatic
sac.[well established][VHOG];
