The olfactory bundle, also known as the olfactory tract, pertains to a key neural structure involved in the sense of smell. Aside from its primary name, there are several synonyms that can be used to refer to this sensory pathway. One such synonym is the olfactory nerve tract, which highlights the connection between the olfactory system and the brain. Another synonym is the fila olfactoria, a Latin phrase that emphasizes the importance of these neural fibers in relaying information from the nose to the brain. Lastly, the term olfactory pathway can be used interchangeably, emphasizing the sequential route by which odor information is processed within the brain.
