Exam 4: How Do Neurons Use Electrical Signals to Transmit Information 

What are voltage-sensitive ion channels?

What are nodes of Ranvier, and what role do they play in the conduction of nerve impulses?

The repolarization of the neuronal membrane is largely due to the:

The patch technique involves:

An action potential is:

Which technology is used to observe the plaque that forms at sites of myelin loss in patients suffering from multiple sclerosis?

A change in the resting potential from -70 mV to -65 mV is called:

An action potential usually goes only in one direction in an axon because:

What is a voltmeter?

Voltage-sensitive sodium channels are active:

What are the two primary reasons refractory periods are important for the conduction of nerve impulses?

Channels in the cell membrane are formed by:

The _____ acts in a way similar to a democracy in that it "counts votes" from incoming EPSPs and IPSPs, and if there is enough excitation, an action potential will fire.

Tetrodotoxin (puffer fish poison) mainly influences the role of:

_____ may play a role in the neural plasticity that is associated with learning.

At rest, the concentrations of _____ are higher inside of a neuron, whereas the concentrations of _____ are higher outside of a neuron.

The resting potential of the inside of an axon, relative to the outside:

Lou Gehrig disease is also known as:

How does the nerve impulse travel from the axon hillock to the end of the axon without degrading in magnitude?

Depolarization is primarily linked with _____, whereas hyperpolarization is mainly linked with _____.
