lachrymal organs are a combination of anatomical structures that produce tears and assign them to an excess of the nasal cavity.They are a pair formation.In order to carry out their functions in connection with the anatomical location of these agencies share in the lacrimal apparatus and slezosekretorny.Allocates secret comprises incorporating enzymes that not only moisturize corneas, but also protects it from inflammation.Tear fluid during blinking uniformly distributed over the surface.
lachrymal glands, which secrete a watery secretion containing a potent antibacterial substance acts as lysozyme, are located in the recesses of the orbit bone over the outer edge of the eye.Their length is about 2 centimeters, and they have a great similarity with the almonds.Lachrymal glands consist of two parts: the orbital (top) and palperbalnoy (bottom), which are separated by a tendon muscle that raises the upper eyelid.In addition, there are additional lacrimal glands.They are mainly located in the conjunctiva of the upper arch.
In order to effectively moisturize the eyeball requires no more than 1 ml a day of tears, and generate additional glands.If there are no abnormalities, they excel with their functions.The main lacrimal glands begin their work, if there are any irritants that cause increased tearing.This happens when exposed to various irritants, foreign body in the cornea or conjunctiva, severe pain, too bright blinding light, an excess of emotion.
lachrymal path are rather complex anatomical education, which consists of many elements.It is for him tear fluid moves into the conjunctival sac, and then discharged into the nasal cavity.From their normal functioning depends largely on the health of this important body is the eye.
tear ducts of 12 units located in each gland and it is for him a secret through the holes provided in the roof of the upper eyelid, enters into the conjunctival sac.On the inner edge of the upper and lower eyelids are small lumps with holes, which are called lacrimal points.Gathered in the lacrimal lake excess secretion through them is carried away by the tear ducts, which are also called tubules.Then he falls into a kind of a collector - the lacrimal sac, and then into the nasal cavity, where it evaporates, moistening it is in the air.
Malfunctions lacrimal organs can be caused by many factors, including inflammation of the lacrimal gland.In this case the tear fluid produced may be too small so much.The main symptoms of disease of the lacrimal glands are: watery eyes, a feeling of friction in the eyes, swelling of the upper eyelid.In acute inflammatory conditions, patients have pain, chronic diseases are none.
lachrymal gland with age produce less secret.This is especially true for women during hormonal changes.There is a decrease in the amount of tears and Sjögren's syndrome - disease rheumatoid nature is not entirely clear from the causes of.
Naturally, when the number of allocated secret weeping greatly increased.A similar phenomenon occurs when the eye injury, burns, foreign bodies, irritation, for example, when cleaning the onions, etc.Thus the body reacts to protect the eye.Inflammation of the lacrimal glands often occurs during the development of infectious diseases such as influenza, mumps, scarlet fever.If swelling of the lacrimal gland is painless and lasts long enough, it is possible to suspect the presence of chronic diseases, such as tuberculosis, diseases of the circulatory system, syphilis and others.
