| Name: | endolymphatic sac |
|---|---|
| Synonyms: | |
| Definition: | Pouch at the end of the endolymphatic duct that helps regulates pressure on the inner ear. The endolymphatic sac is separated from the endolymphatic duct by a dynamic lamellar barrier. The lamellar barrier is composed of long, thin lamellar sheets that form tongue-and-groove structure or interwoven broadly overlapping structures. In adults, the endolymphatic duct and sac are partially encased within the temporal bone such that the distal end of the endolymphatic sac protrudes out of the temporal bone into the cranial cavity . |

Note that the bearer of the quality is the whole, not the part. Formally: If a bearer entity e has fewer parts of type X at time t, then the number of instances x of X at t such that x part_of e is < n, where n is either the normal number for comparable entities, or n is stated explicitly. This case includes the limit case, where the bearer lacks all parts of the specified type. |
