relating atrium and ventricle
Etymology
'auriculoventricular' originates from New Latin/medical Latin, specifically from the combining form 'auriculo-' from Latin 'auricula' (meaning 'little ear', used for the atrium) and 'ventricular' from Latin 'ventriculus' (meaning 'little belly' or 'ventricle'), with the adjectival suffix '-ar'.
'auriculoventricular' was formed in medical New Latin by combining 'auriculo-' + 'ventricular' (compare New Latin 'auriculoventricularis') and was adopted into modern English medical terminology without major change.
Initially it denoted 'pertaining to the auricle (atrium) and the ventricle'; this core meaning has been retained in current medical usage.
