Pain-sensitive neurons conduct action potentials from the skin or teeth to sites in the brain involved in pain perception. To most effectively prevent the perception of pain a dentist would inject [a] near the [b] to [c] the generation of action potentials that would send a signal to the brain.

Activity 7:  The squid utilizes a very large-diameter, unmyelinated axon to execute a rapid escape response when it perceives danger.  Due to the large-diameter, the velocity of the action potential is [a] that of a smaller diameter axon, because the larger fiber has less internal resistance to local current.  This allows a greater flow of ions in a set time bringing adjacent areas of the membrane to threshold, allowing a [b] conduction velocity of action potentials and a rapid escape response. This helps compensate for the lack of myelin.
