Anatomy of the lachrymal tract


Anatomy of the lachrymal tract

The main function of the lacrimal gland - is the development of lacrimal fluid. In addition to the lacrimal gland, lacrimal fluid is produced by special cells, which are located deep in the mucous membrane of the eye (conjunctiva) and are called goblet.


Lacrimal gland lies in the lacrimal gland fossa below the upper edge of the orbit at the outer corner of eye. It consists of lobules. Ducts of the lacrimal glands open into the upper body of the conjunctiva (under the upper eyelid at the outer corner of the eye). By brook lacrimal (the groove along the inner edge of the lower eyelid, between it and the eyeball), a tear comes to tearful lake - at the inner corner of eye. In the inner corner of eye to upper and lower eyelids are the tabs - lacrimal papilla. At the top of the lacrimal papilla is lacrimal point.

Lacrimal point - this is the inlet of the tear ducts. Lacrimal ducts empty into the lacrimal sac. Lacrimal sac passes below a nasolacrimal duct, which opens into the nasal cavity. This channel shows a tear from his eye into the nasal cavity.
