generally speaking, all membranes demonstrate a Na/K pump activity
true
generally speaking, cell membranes demonstrate a resting membrane potential
true
the amplitude of the action spike is a function of the concentration gradient of Na+ across the cell membrane.
true
only excitable cell membranes demonstrate an action potential.
true
the larger diameter of a neuronal axon implies a faster speed of conduction.
true
a myelinated neuron can conduct 50x faster than the fastest unmyelinated neuron
true
tetraethyl ammonium is a Na+ channel poison.
false
a local anesthetic of often one that reversibly blocks the Na+vgc
true
generally speaking, Na+vgc are fast to open and fast to close when compared with K+vgc that open and close slowly
true
when a membrane is in state of absolute refractory, only the strongest of the stimuli (high amplitude, plus high duration) can cause an action potential generation.
