🇬🇧
/ˌveɪzəˈməʊʃən/
rhythmic movement of blood-vessel tone
Etymology
'vasomotion' is formed from the combining prefix 'vaso-' (from Latin 'vas', meaning 'vessel') and the English word 'motion' (from Latin 'motio', 'movere', meaning 'to move').
'vas-' originates from Latin 'vas' meaning 'vessel'; the prefix 'vaso-' entered New/Modern Latin and was adopted into English medical formation. 'Motion' comes from Latin 'motio' via Old French and Middle English into modern English, combining to form the compound 'vasomotion' in medical usage.
Originally the components literally conveyed 'movement of a vessel'; in modern medical usage the compound has come to mean specifically the rhythmic changes in vascular tone and diameter rather than any general movement of a vessel.
