this represents a part of the entire arch mesenchyme (UBERON:0010046), and is therefore a superclass of the individual arch mesenchyme classes. Alternate definition: primordial embryonic connective tissue associated with the branchial arches, consisting of mesenchymal cells supported in interlaminar jelly, that derive mostly from the mesoderm and contribute to facial and cranial nerve-associated structures.
