antidromy
|an-ti-dro-my|
/ænˈtɪdrəmi/
movement in opposite direction
Etymology
'antidromy' originates from Greek, specifically the word 'antidromos', where 'anti-' meant 'against' and 'dromos' meant 'running or course'.
'antidromos' passed into New Latin/Neo-Latin forms (e.g. 'antidromia') and was later adopted into English as 'antidromy' to name the phenomenon of opposite-direction conduction.
Initially it meant 'running or moving against (a direction)', and over time it evolved to denote specifically 'conduction or movement opposite the normal direction' (especially in physiology).
