A systematic listing of names, such as SNOMED CT, is recognized as a nomenclature because it provides a standardized system for naming and classifying concepts in healthcare. This structured approach allows for precise communication about medical diseases, procedures, and other concepts, facilitating information sharing among healthcare professionals.

Nomenclatures like SNOMED CT organize terms in a way that captures detailed relationships and hierarchies, making it easier to document and retrieve clinical information accurately. They serve as a reference for consistent usage, ensuring that everyone interprets the medical terminology uniformly.

In contrast, classification systems categorize data into predefined groups based on similarities and differences, which may not necessarily focus on the naming conventions. Vocabulary may refer to the general set of terms used in a specific field but does not always imply systematic organization or relationship among the terms. Topology typically relates to the study of spatial properties and may not directly apply to the structured naming conventions found in medical terminology.
