Pathway crosswalk, v1.1

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 table provides a crosswalk between structures in the<br>blood vasculature, lymph vasculature, and peripheral nervous system (PNS) ASCT+B tables. The Relationship column<br>indicates the relationship between Structure1 and Structure2. In this version of the crosswalk, there are three types<br>of relationships: (1) “adjacent_to” is being used here for neurovascular bundles; (2) “connects_to” indicates arterial<br>vessels that connect to venous structures; and (3) “anastomosis_to” is used for anastomoses, where vessels connect to<br>form loops.

[解剖结构、细胞类型及生物标志物（Anatomical Structures, Cell Types, plus Biomarkers，简称ASCT+B）表格](https://humanatlas.io/asctb-tables)旨在收录人体解剖部位、细胞分类体系以及用于识别细胞类型的生物标志物。该类表格由国际专家团队共同撰写并审核。
本对照表用于建立血管系统、淋巴系统及外周神经系统（Peripheral Nervous System，简称PNS）的ASCT+B表格中各类结构间的关联对应关系。
“关联关系”列用于说明结构1与结构2之间的关联类型。
本版对照表共包含三类关联关系：(1) “adjacent_to” 用于指代神经血管束；(2) “connects_to” 用于表示连接静脉结构的动脉血管；(3) “anastomosis_to” 用于描述血管吻合现象，即多条血管相互连接形成环状结构。
