Q

TENS. Which nerve fibers are effected, what theory is it based on?

A

Transcutaneous electrical nerve srimulation
conducted through the skin to eleviate pain.
Uses the gate theory.
A-delta (small myelinated) nerve fibers and C fibers (small unmyelinated), activating A-beta nerves o block pain transmition.

22
Q

When does depolarization of a cell membrane occur?

A

+30mV (millivolts)

23
Q

Can a cell’s action potential be activated after depolarization?

A

No, it will be in the absolute refractory period; unless a greater than usual stimulus is present (relative refractory period.
