Where is the crus of fornix located in relation to the body of fornix?

The crus of fornix is located posterior to the body of the fornix. The fornix is a C-shaped bundle of nerve fibers that acts as a major output tract for the hippocampus. It is divided into two crura (the plural of crus) that extend posteriorly into the brain. The body of the fornix is a central part of the structure that connects the two crura.

In anatomical terms, the superior structure is often referred to as being "above" or "anterior", while the inferior or more distal structures are considered to be "below" or "posterior." In this context, since the crura project posteriorly from the body of the fornix, the position of the crura is indeed described as posterior relative to the body. Understanding this spatial relationship is important for appreciating how various structures in the brain are interconnected and how they contribute to functions such as memory and spatial navigation.
