1. Nasolacrimal duct tube including lachrymal passage

2. The lacrimal Canaliculi form the first part of the nasolacrimal drainage apparatus that drains tears produced by the lacrimal gland.

3. The Canaliculi are segments of the tear duct system that connect the puncta to the lacrimal sac and remaining nasolacrimal duct

4. A mucosal autograft composed of agger nasi cell mucosa was used to reconstruct the lacrimal sac mucosa in a young woman with a Cicatrised lacrimal sac and obstructed nasolacrimal system

5. The lacrimal drainage apparatus consists of the puncta on the upper lid and the lower lid, the canaliculi, the common Canaliculus, the lacrimal sac, and the nasolacrimal duct

6. Aims A study was designed to evaluate the influence of head conformation on the course of the nasolacrimal drainage system (NDS) in 31 Brachycephalic and 15 mesocephalic cats using computed tomography (CT), CT-dacryocystography and anatomical methods.

7. ‘Some posit that it crosses the membrane at the channel periphery or traverses the Canaliculus.’ ‘The lacrimal drainage apparatus consists of the puncta on the upper lid and the lower lid, the canaliculi, the common Canaliculus, the lacrimal sac, and the nasolacrimal duct.’
