Cataphoresis is the process of fusing an acidic (positive) product into deeper tissues using galvanic current from which pole toward which pole?

Cataphoresis is the process of fusing an acidic (positive) product into deeper tissues using galvanic current from which pole toward which pole?

• A. From the positive pole toward the negative pole
• B. From the negative pole toward the positive pole
• C. From the neutral pole toward the charged pole
• D. From the positive pole toward the neutral pole

Answer: (A)

Cataphoresis uses direct current to push positively charged ions from the site of the positive electrode into deeper tissues. An acidic product is made of positive ions, so under the electric field these cations migrate toward the negative electrode (the cathode). Since the current flows from the positive pole toward the negative pole, the positive ions move along that path—from the positive pole toward the negative pole—and into the tissues. The ions would not move toward the positive pole, and only a negatively charged ion would migrate toward the positive pole.
