- action potentials are conducted through nerve fibers
- action potentials are one-directional
- action potentials are all-or-nothing
- action potential signals are coded by frequency

Action Potential Speed
Initiating an Action Potential
A specific neurotoxin is discovered that alters nerve cell function. When a signal is initiated at one end of a very long nerve cell, the signal's strength significantly decreases as it travels towards the other end. Based on this observation, what is the most likely functional consequence for the organism?
A nerve cell must transmit a signal from the spinal cord to a muscle in the foot, a significant distance. For the signal to arrive at the muscle with the same strength it had when it started, which of the following mechanisms is essential?
