<prompt> All of the following are propeies of local anesthetics EXCEPT:Blockade of voltage dependent Na channelsPreferential binding to resting channelsSlowing of axonal impulse conductionIncrease in the membrane refractory period  <response>: - Local anesthetic receptor is located within the channel in its intracellular half. - LA traverses the membrane in unionized form. - LAs act from within the neuron and are more active when the neuron is rapidly firing i.e., Na channels are open. so it doesnot act in resting form.
