What is the tear bone?

Lacrimal bone is one of the 22 skull bones and is in fact the smallest of these bones. It is located in orbit or eye outlet, it is a flat, quadrangle bone found on the side of the socket closest to the nose. Its boundaries touch four other bones of the skull: ethmoid and frontal bones of the skull and Maxilla and lower nasal bones of the face. On the surface of the lacrimal bone, which is directed outward from the nose, there are two structures important for the eye function. It is a tear that collects excessive tears that have been removed from the eye by the lacrimal ducts, and the nasal canals that transmit tears from the tear from the tear to the nasal fossa, the cavity immediately behind the nose. The remaining 14 are found in the face. These bones are shaped and supported by jaw, upper lips, faces, nose and eye outlet. The large cavity, which is in orbit, consists of several adjacent bones, including a sacrimal bone. They also intersect into the creation of this outlet, are sphenoid, ethmoid, maxilla, zygomatic, frontal and palatine bones.

The great bone corresponds to the inner corner of the eye along the side of the nose bridge. On the front of this bone is Maxilla, the bone of the face that felt immediately below the eye socket. The long front or front limit of the tear bone is articulated with the surface on Maxille known as the front process.

along the edge of the bone, which is the deepest in the eye socket, is the ethmoid bone of the skull. The narrow upper edge of the sacrimal bone is equal to the front bone, the large bone of the skull that forms the forehead. A similarly narrow lower limit encounters the lower nasal cona, a curly projection of the named bostipro its similarity to the coast, which is located inside the nasal cavity behind the nose.

This four -sided bone, long from top down and narrow from side to side, acts as structural support for the tear gland, which consists of tear channels, tear bag and nasolakrimal channels. The canalicles are found close to the tear bones and carry tears PRYČ from the eyeball to the hell, the structure simply superficial to the top of the cheap bone. When located at the upper end of the nasal canals, the tear is like a pelvis in which tears are collected before emptying into the nasolacal canals, which monitor the length of the tear bone down and store tears in the nasal cavity.
