What is the hell?

damn is the upper part of the extended part of the nasolacrimal channel, which is known as a tear channel in laid terms. On the other hand, tears are one of the main parts of the tear apparatus. Lakrimal SAC plays a role in the production and outflow of tears in the eyes.

with an oval shape has a damn length of about 0.47 to 0.59 inches (12 to 15 mm). The upper end of the bag has a closed and rounded structure. Its lower end runs into the tear channel. Cover the outer surface of the bag is the fibrous part of the medial palpebral ligament or tendo vineyard , which is responsible for connecting the edge of the edge of the eye level. Muscle responsible for closing the lids - orbicularis Oculi - exceeds the inner surface of the bag.

located in a deep furrow, the lacrimal bag is created by a cheap bone and the front process of Maxilly. The most and least robust bones of the face, the lacrimal bone are located in the jacket from its upper half by opening called Lacrimal Fossa or Fossa for the hell. The lower part of this opening is a place where tears are located.The main process of the maxilla or upper jaw is connected to the formation of SAC by connecting with the inner edge of the longitudinal groove with a cheap sulk or sulcus cheapimalis .

The sacrimal bag connects two parts of the tear apparatus: tear channels and nasolakrimal channel. It drains tears from the surface of the eye through the tear channels, which is equally commonly called lactic channels and tears. These are associated with VAC excellent channel, which travels to it in the middle way and a longer and larger lower channel under the superior channel, which leads in a horizontal course. The tear channel then transports tears from the bag of the donos cavity, the prefix "NASO".

In some cases, the nasolacrimal channel can collect excess tears from the hell. The excess fluid is then placed in the lower nasal, which is the largest of the three nose holes. This explains why the nose begins to run when you scream or have watery eyes because of an allergic reaction. FoldYet tears can also facilitate orbicularis oculi. This happens especially during flashing when the cheap SAC pump internally and externally.
