Conjunctival fornix

Conjunctival fornix

The conjunctival fornix is ​​an anatomical structure that connects the upper and lower parts of the eyeball. It is located in the anterior part of the orbit, behind the lacrimal sac and orbit. The study of the conjunctival vault is an important element in the study of the anatomy of the eye and serves as the basis for further research in the field of ophthalmology.

general description

The vault is the structure connecting the upper and lower walls of the orbit. In humans, it is shaped like a semicircle and consists of several layers of tissue, including fascia, adipose tissue and membrane. The location of the arch provides it with a special function - it protects the eyeball from injury when the head is displaced or hit. In addition, the arch performs a shock-absorbing and supporting function.

An important feature of the arch is that its structure can change with age, and in young people it can be distinguished better than in older people. The thickness of the arch varies from 4 mm in childhood to 6-8 mm in adults. Also, its shape is not always the same and can vary depending on the side of the body (right and left).

In addition to the eye area, the fornix relates to the frontal bone (pineal fossa), cerebellum, etc. There is only one point of intersection with other brain structures - the sphenoid-mastoid suture. The anterior part of the fornix includes other structures such as the choroid, retina, episcleral tendon
