Hi Phil,
You can use this to get the list of all anatomy entity classes
AnatomyData["Classes"]
For each of them you can get a list of the corresponding entities e.g. for Bones
EntityClass["AnatomicalStructure", "Bones"]["Entities"]
Any of them can be passed to AnatomyPlot3D
e.g. for FrontalBone
AnatomyPlot3D[Entity["AnatomicalStructure", "FrontalBone"]]
You can get also get the list of properties e.g. for FrontalBone
Entity["AnatomicalStructure", "FrontalBone"]["Properties"]
To get an Association
of all the classes and entities
entities = <|CanonicalName@# -> EntityClass["AnatomicalStructure", CanonicalName@#][
"Entities"]|> & /@ AnatomyData["Classes"] // Association;
Then e.g. for Arteries
entities["Arteries"]
