Anatomical site

An anatomical site is defined as a specific part, region, or location within the body, such as an organ, tissue, or limb (National Cancer Institute, 2024). It serves as a descriptive category in medical coding, pathology, and clinical trials to specify where a disease is located or where a therapeutic intervention is applied. Unlike therapeutic targets such as receptors, enzymes, or transporters, an anatomical site is a macro-scale physical structure and does not possess a specific molecular sequence or biochemical function that can be directly modulated by a drug. Because it represents a physical space rather than a functional biological molecule, it does not have associated molecular classifications, signaling pathways, or direct drug-binding mechanisms. Consequently, this term is considered an incorrect entry for a database of molecular therapeutic targets and is instead used for topographical classification (MeSH, 2024).
