Limbus

Limbus (from Latin limbus - edge, border) in anatomy means the edge or border of an organ or structure.

For example, the limb of the sclera of the eye (limbus sclerae) is the junction of the transparent cornea and the white membrane of the eye (sclera). The scleral limb separates the cornea from the sclera and contains small blood vessels that provide nutrition to these structures of the eye.

The term limbus is also used to refer to the edge of other anatomical structures such as the lungs, spleen, kidneys and uterus. The limbus performs an important function - it delimits and connects adjacent anatomical formations of organs and tissues.

Limbo is the edge or boundary of something. In anatomy, the limbus is the edge or border, for example, the limbus of the sclera of the eye, which is the junction of the cornea with the eyeball. The limbus can be either thin or thick, and also have different shapes and sizes.

The limbus is an important anatomical element of the eye, as it protects the eyeball from external influences and maintains its shape. In addition, the limbus is involved in the formation of a visual image, since light passes through it, which then hits the retina.

However, the concept of limbus exists not only in anatomy. In literature, limbo is often called a state when a person is on the border between life and death. This may be due to various reasons such as illness, injury or accident. In this case, limbo can mean a moment when a person’s life is under threat, but there is still a chance to save it.

In general, limbo is a concept that has wide application in various areas of life. It can be used to describe boundaries and edges, as well as to indicate a state where a person is balancing between life and death.

The limbus is the part of the eye that comes into contact with the tear fluid, the sclera, and the cornea. This anatomical structure plays an important role in maintaining the health of the ocular surface. Perhaps many of you are familiar with dry eye syndrome, which is characterized by a lack of tear secretion. If you have such a problem or are simply interested in the structure of the human eye, then the article below will help you understand more about the limbus.

**Limb is an edge**   Translated from Latin as edge. The term was first coined by **Hippocrates of Caesarea in the fourth century BC**. He used it to detect pain that usually occurs after prolonged exposure to the sun or severe hypothermia. In the first case, not only the skin, but also the tissue in the internal organs of the body peels from direct sunlight. It begins to cause discomfort, which resembles a sharp pain. The second case is much simpler and is associated with a drop in body temperature, that is, the person freezes.

*The limbic system of the brain is involved in the regulation of almost all vital functions*

The limbus is also used in ophthalmology, where the term refers to the posterior surface of the cornea. It is usually divided into three zones:

- the anterior limb of the cornea is a continuation of the white shell in the anterior part of the sclera and is separated from it by the optic bone disc; - the middle limbus is located in the center of the cornea; - the posterior limbus is a continuation of the cornea and passes into its posterior wall.

A more detailed study of the structure of the body showed that this system has anatomical significance, since its name is almost identical to the name of the ancient sea god of love - **Limpos**. This is the external embodiment of emotions and impulses among the inhabitants of the Mediterranean. He was depicted as a deity wearing the color saffron, which, according to many scientists and psychologists of this period, was a symbol of sensuality and was associated with the emotional reaction of the human soul.
