fornix
In neuroanatomy, this term refers to a specific white matter tract. It is used almost exclusively in medical, psychological, or biological contexts to describe the structural connectivity of the limbic system. Because it refers to a unique anatomical structure, it is typically treated as a singular entity in clinical descriptions.
In architectural history, the term describes a vaulted arch or gateway. This usage is highly specialized and primarily found in texts concerning Roman antiquity or classical architecture, where it distinguishes a specific type of curved masonry from general arches.
