Anatomical Structures, Cell Types, plus Biomarkers (ASCT+B) table for Skeleton, v1.2

Anatomical Structures, Cell Types, plus Biomarkers (ASCT+B) tables (https://humanatlas.io/asctb-tables) aim to capture<br>anatomical human body parts, the typology of cells, and biomarkers used to identify cell types. The tables are<br>authored and reviewed by an international team of experts. This ASCT+B table contains a hierarchical “partonomy” of<br>the human skeleton. The top-level anatomical structure (“AS/1”) is “skeleton” for all structures. The second level<br>(“AS/2”) divides the skeleton into “appendicular skeleton” and “axial skeleton”. The third (“AS/3”) and fourth<br>(“AS/4”) levels further divide the skeleton by body region and sub-region, respectively. The fifth level (“AS/5”)<br>lists individual bones. Finally, the sixth level (“AS/6”) contains bony landmarks and parts of bones. Note that the<br>main purpose of this table is to provide a comprehensive list of bones and their location in the body. Individual<br>bones, bone tissues, and joints might have their own ASCT+B table, which provides more detail about its anatomical<br>structure, cell types, and biomarkers.<br> <br>**Bibliography:** <br><br>* Börner, Katy, Sarah A.
