Query Anatomical Pathway Between Entities

Finds the shortest anatomical pathway between two entities (muscles, bones, nerves, etc.) in the knowledge graph. Useful for tracing innervation chains, biomechanical linkages, and anatomical relationships.

Usage

mskPathwayQuery(from, to, hub = NULL, max_depth = 5L)

Arguments

from

Character, the source entity name (e.g., "Biceps Brachii").

to

Character, the target entity name (e.g., "C5").

hub

A PhysioAnnotationHub object (NULL loads default).

max_depth

Integer, maximum BFS depth (default: 5).

Value

A list with:

path

Character vector of entities along the path

predicates

Character vector of relationship types between entities

depth

Integer, path length

description

Human-readable path description

found

Logical, whether a path was found

Clinical Validity

Pathways reflect relationships encoded in the knowledge graph. The shortest path in the KG may not correspond to the most clinically relevant connection. Always verify pathway interpretations against anatomical references.

Examples

if (FALSE) { # \dontrun{
path <- mskPathwayQuery("Biceps Brachii", "C5")
cat(path$description, "\n")
} # }
