The lacrimal drainage structures begin to form during the fifth week of gestation as a crease between the frontonasal and maxillary processes, the nasolacrimal groove. A solid cord of ectodermal tissues separates from the surface and enters this groove. This tissue canalizes and forms the lacrimal sac and nasolacrimal duct On the nasal surface of the body of the maxilla, in front of the opening of the sinus is a deep groove, the lacrimal groove (or lacrimal sulcus), which is converted into the nasolacrimal canal, by the lacrimal bone and inferior nasal concha; this canal opens into the inferior meatus of the nose and transmits the nasolacrimal duct.. Additional image lacrimal groove: [TA] the groove in the nasal surface of the maxilla that, together with the lacrimal bone, forms the fossa for the lacrimal sac.

In front of the lacrymal crest is a longitudinal groove, the lacrimal sulcus (sulcus lacrimalis), the inner margin of which unites with the frontal process of the maxilla, and the lacrimal fossa is thus completed. The upper part of this fossa lodges the lacrimal sac, the lower part, the naso-lacrimal duct The nasolacrimal groove extends between the developing lower lateral nose and the medial orbit. The ectoderm along the floor of each groove thickens to form a solid epithelial cord, which then detaches from the groove and canalizes to form the nasolacrimal duct and lacrimal sac.

Nasolacrimal canal - Wikipedi

The lacrimal sac contributes to the production of tears. The lacrimal sac is the upper widened part of the nasolacrimal duct, which is known as the tear duct in layman's terms. In turn, the tear duct is one of the main parts of the lacrimal apparatus. The lacrimal sac plays a role in the production and drainage of tears in the eyes Notch signaling in the division of germ layers in bilaterian embryos Bilaterian embryos are triploblastic organisms which develop three complete germ layers (ectoderm, mesoderm, and endoderm). While the ectoderm develops mainly from the animal hemisphere, there is diversity in the location from where the endoderm and the mesoderm arise in relation to the animal-vegetal axis, ranging from.
