The middle layer of the heart, consisting of cardiac muscle.[AAO]
Robust muscular tunic of the heart which forms the basic part of its walls. Its external surface is covered by the pericardium and its internal one by the endocardium. [Dorian_AF, Elsevier's_encyclopaedic_dictionary_of_medicine, Part_B:_Anatomy_(1988)_Amsterdam_etc.:_Elsevier][VHOG]
TODO - check 'Myocardum proper' in FMA. We superclass the more generic class for now. FMA has is_a muscle layer - should we add this? ZFA and BTO both have is_a 'cardiac muscle' (tissue?). But in U we also follow FMA and have cardiac muscle tissue of myocardium (there is also Fibrocollagenous connective tissue of myocardium), which would be identical (see issue-10). Note that GO also treats left/right ventricular cardiac muscle tissue synonymous with ventricular myocardium
