What are the four mechanisms underlying electrical currents
- Galvanotaxis to attract appropriate cell types
- Activate cells by alerting cell membrane function
- Enhance antimicrobial activity
- Enhance circulation

true
Antimicrobial effects- HVPC and DC both (do not/can) kill bacteria
can
What two currents can kill bacteria
HVPC and DC
Which type of current does NOT kill bacteria
AC (alternating current)
Is the voltage needed to kill microbes feasible in a clinical setting?
no
Although voltage needed to kill microbes is not feasible in the clinical setting, more tolerable voltage can (enhance/reduce) the antibiotic in the destruction of ______
enhance, biofilm
Which term describes the movement of cells in response to the electrical field
galvanotaxis
_____ is the movement of cells in response to the electrical field
galvanotaxis
The rule of thumb regarding polarity and wounds states that
(positive/negative) electrodes promotes healing of inflamed or infected wounds and
(positive/negative) electrodes promote healing of wound without inflammation
negative; positive
In regards to the rule of thumb of polarity and wounds, when would you use negative electrodes
To promote healing of inflamed or infected wounds
In regards to the rule of thumb of polarity and wounds, when would you use positive electrodes
To promote healing of wounds without inflammation
