Across
- 1. an electrical circuit consisting of two poles that operate independently of other circuits
- 4. normal and sufficient nerve supply to a muscle, body area, and so on
- 5. total contraction of a muscle achieved through the recruitment and contraction of all motor units
- 8. both phases are equal
- 10. the faculty or incorrect healing of bone
- 12. value takes into account the current's amplitude and duration
- 15. the CNS process of filtering out a continuous, nonmeaningful stimulus
- 17. points that according to the theory of acupuncture, connect skin areas to deeper energy channels, stimulating master points results in systemic changes

Down
- 2. one-half of its complete cycle and takes into account the amount of time the current is flowing
- 3. a slow-healing or nonhealing break in the skin
- 6. an imaginary shell in which the electrons responsible for chemical reactivity orbit around the nucleus of an atom
- 7. a residual electromagnetic field created by two unlike charged
- 9. the maximum distance that the pulse rises above the baseline
- 11. one billionth of a second
- 13. a measure of acidity or alkalinity bases
- 14. stimulation is an intensity that produces a visible muscle contraction without causing pain
