CROSS-SPECIES ANATOMY - ANNOTATIONS

The Basic subset of the UBERON integrated, cross-species anatomy ontology is downloaded weekly from http://berkeleybop.org/ontologies/uberon/basic.obo. For more information about this ontology see the "About" page on the UBERON website at http://uberon.github.io/about.html.

Definition:The upper dilated end of the nasolacrimal duct that is lodged in a deep groove formed by the lacrimal bone and frontal process of the maxilla; it connects the lacrimal canaliculi, which drain tears from the eye's surface, and the nasolacrimal duct, which conveys this fluid into the nasal cavity; like the nasolacrimal duct, the sac is lined by stratified columnar epithelium with mucus-secreting goblet cells, and is surrounded by connective tissue.
Synonyms:exact_synonym: lachrymal sac;   lacrymal sac
