Definition of conduction in English:


Line breaks: con|duc¦tion
Pronunciation: /kənˈdʌkʃ(ə)n


[mass noun]
1The process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
More example sentences
  • In solids that conduct electricity, heat conduction is further enhanced by the drift of free electrons.
  • Under equal electrochemical potential gradients, conduction of protons across ion channels occurs at a rate typically an order-of-magnitude higher than that of other small ions.
  • Vanadium-vanadium bonds are stable below the transition temperature, which ‘lock’ the electrons and prevent conduction.
1.1The process by which sound waves travel through a medium.
More example sentences
  • Deafness, therefore, is caused by conduction deafness.
  • We have seen how the normal outer and middle ears participate in sound conduction.
  • Furthermore a database having typical sound conduction components for a number of typical hearing impairments is provided.
1.2The transmission of impulses along nerves.
More example sentences
  • Disturbances in this ration can alter cardiac rhythms, transmission and conduction of nerve impulses, and muscle contraction.
  • Local anesthetics block the generation and conduction of all nerve impulses - sensory, motor, and autonomic - depending on the site of injection.
  • Its most important action is its ability to block the initiation or conduction of the nerve impulse following local application.
1.3The conveying of fluid through a channel.
More example sentences
  • This number is explained in terms of channel architecture and conduction mechanism.
  • The results show a dislocation of the nanotube indicative of a possible disassembly process that may influence the channel conduction.
  • Carbon nanotubes, unmodified (pristine) and modified through charged atoms, were simulated in water, and their water conduction rates determined.


mid 16th century (in the senses 'provision for safe passage' and 'leadership'): from Latin conductio(n-), from the verb conducere (see conduct).
