external ontology notes

this class denotes a combination of fibrous PC + PC sac (itself a combination of cavity, epithelium and connective tissue). Many sources use the term 'pericardium' to denote either just the serous membrane (ZFA) or the epithelium (GO)

In GO the concept of pericardium is developmental implicitly epithelial, but here it represents a multi-tissue structure encompassing the sac (epithelium plus connective) and cavity

we follow FMA in dividing pericardium into pericardial sac and fibrous pericardium
