[Answer] An axon that is more negative than the resting membrane potential is said to be _______.

Answer: hyperpolarized
An axon that is more negative than the resting membrane potential is said to be _______.
The potassium channels exhibit a delayed reaction to the membrane repolarisation and even after the resting potential is achieved some potassium continues to flow out …
Hyperpolarization is a change in a cell’s membrane potential that makes it more negative. It is the opposite of a depolarization. It inhibits action potentials by increasing the stimulus required to move the membrane potential to the action potential threshold. Hyperpolarization …
Repolarization typically results from the movement of positively charged K + ions out of the cell. The repolarization phase of an action potential initially results in hyperpolarization attainment of a membrane potential termed the afterhyperpolarization …

During the rising phase the membrane potential depolarizes (becomes more positive). The point at which depolarization stops is called the peak phase. At this stage the membrane potential reaches a maximum. Subsequent to this there is a falling phase. During this stage the membrane potential becomes more negative returning towards resting potential.
The refractory period in a neuron occurs after an action potential and generally lasts one millisecond. An action potential consists of three phases. Phase one is depolarization. During depolarization voltage-gated sodium ion channels open increasing the neuron’s membrane conductance for sodium ions and depolarizing the cell’s membrane potential (from typically -70 mV toward a positive potential). In other words the membrane is made less negative…
This difference in charge is called the cell’s membrane potential . In the process of depolarization the negative internal charge of the cell temporarily becomes more positive (less negative ). This shift from a negative to a more positive membrane potential occurs during several processes including an action potential . During an action potential the depolarization is so large that the potential difference across the cell membrane …
Similarly to the resting membrane potentials of plants and animals the peaks correspond in a similar manner: they are commonly more negative . Dionaea’s action potential usually maximizes at -20mV approximately 60mV less than an average nerve cell. Falling Phase and After-hyperpolarization
The voltage clamp is an experimental method used by electrophysiologists to measure the ion currents through the membranes of excitable cells such as neurons while holding the membrane voltage at a set level. A basic voltage clamp will iteratively measure the membrane potential and then change the membrane potential (voltage) to a desired value by adding the necessary current. …
