Musculoskeletal 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 describes relationships between anatomical<br>structures in the muscular system and skeleton ASCT+B tables. This includes (1) bone “adjacent_to” bone crosswalks and<br>(2) muscle “attached_to” bone, ligament, tendon, fascia, or skin crosswalks. The bone “adjacent_to” relationships may<br>indicate a joint and joining structures. The “attached_to” relationships have a “Relationship2” value of<br>“has_muscle_origin” or “has_muscle_insertion”. The focus of this initial version of this crosswalk table is the upper<br>extremities, but it will be expanded in the future to other parts of the body.
