What is fornix?

In anatomy, Fornix is ​​any structure in the shape of an arch found in the body, but the most common use is to refer to the fornix located in the brain. It is a bundle of C -shaped fibers, also known as axons that transmit signals from hippocamp to other parts of the brain, including septal cores and hypothalamus. This fornix resembles a couple of C -shaped objects located at an angle and touches the upper edge. The lower edges of both objects move outwards, causing both hemispheres of the brain. They then come together and meet at their upper edge, join together to form the body, and then again divide when they reach the rear end and create the front columns. This structure is located in midbrain and makes its arch directly above thalamus.

Fornix is ​​a Latin word for an arch or safe, and this brain structure is thus named only because of its unique shape. Although the exact function and importance in general brain physiology is not clear, it has been shown that surgicalTranssection - fornix cutting along the body - can cause memory loss in humans. There is some debate on what type of memory is influenced by this damage, but it has been found that it correlates most of the memory of evocation than the recognition. This means that IT damage can cause difficulty in raising long -term information, such as details of past events, but has little effect on the ability to recognize objects or known situations.

While the most common definition will refer to this particular brain structure, the term itself can also be used to refer to other structures similar to the arc in the body. Two of the most remarkable are the uterine fornix, which includes several recessed areas placed in the deepest part of the vagina and is created by a protrusion of the cervix into the vaginal cavity and fornix conjunctivae, which refers to a series of accent membrane inserts in the eye. In general, if the term is used without any previous orThe following word, but simply recorded as Fornix, almost inevitably refers to the above brain structure.
