1. FSN must include the word 'structure', 'entire' or 'part' for concepts that are following the SEP model.
For example,
- Liver structure (body structure)
- Entire liver (body structure)
- Liver part (body structure)
2. All descriptions for Entire concept must contain the word 'Entire'.
For example,
FSN | PT | SYN |
---|---|---|
Entire liver (body structure) | Entire liver | |
Entire thumb (body structure) | Entire thumb | Entire first digit of hand |
3. The word 'structure' can be omitted for synonyms.
For example,
FSN | PT | SYN | SYN |
---|---|---|---|
Liver structure (body structure) | Liver structure | Liver | |
Thumb structure (body structure) | Thumb structure | First digit of hand | Thumb |
S concepts are usually named x structure (body structure) or structure of x (body structure). E concepts are usually named entire x (body structure) or x entire (body structure). P concepts are usually named x part (body structure) or part of x (body structure).
Plurals
Outside the anatomy section of SNOMED CT, plurals were primarily used as headers, while the individual concept names were singular. In the anatomy section, we have taken plurals to represent meaningful differences from their singular counterparts.
For example, Skin structure of all fingers in the FSN would mean more than one finger, while Skin of finger would not imply more than one.
