Many medications introduced into the bloodstream cannot directly affect the neurons of the central nervous system because

Conduction along unmyelinated axons is relatively slow

Neurons in which the dendritic and axonal processes are continuous and the cell body lies off to one side are called

The sodium potassium pump

If the potassium permeability of a resting neuron increases above the resting permeability, what effect will this have on the membrane potential?

The all-or-nothing principle states that

What will occur in a graded potential if there is a continuous supply of neurotransmitter?
