Anatomical Structures, Cell Types, plus Biomarkers (ASCT+B) table for Skeleton, v1.0

[Anatomical Structures, Cell Types, plus Biomarkers (ASCT+B) tables](https://humanatlas.io/asctb-tables) aim to<br>capture 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.

解剖结构、细胞类型及生物标志物表格（Anatomical Structures, Cell Types, plus Biomarkers，简称ASCT+B）（https://humanatlas.io/asctb-tables）旨在收录人体解剖结构、细胞分型以及用于鉴定细胞类型的生物标志物。
该表格由国际专家团队联合撰写并审核。
本ASCT+B表格涵盖了人体骨骼的层级化部分-整体分类结构（partonomy）：其顶层解剖结构（AS/1）为覆盖所有相关结构的“骨骼”；第二层（AS/2）将骨骼划分为“附肢骨骼”与“中轴骨骼”；第三层（AS/3）与第四层（AS/4）则分别依照身体区域与子区域对骨骼进行逐级细分；第五层（AS/5）列出单块骨骼；最终第六层（AS/6）则收录骨骼解剖标志点与骨骼亚结构。
需注意，本表格的核心目标是提供一份完整的骨骼列表及其在人体中的位置信息。
单块骨骼、骨组织及关节可拥有专属的ASCT+B表格，此类表格可提供其解剖结构、细胞分型及生物标志物的更为详尽的信息。
