The portions of the neuron that has branches off the soma and receive nerve signals are called the ___________________. Which type of receptor do you find on these structures? If a presynaptic neuron synapses on one of these branches, what do you call that type of synapse (anatomical not chemical)?

State the name of each of the neuroglial cells and their function

When the inside of the neuron reaches ____________ (term and voltage) an action potential will begin. What do we call the changes in membrane potential before it reaches threshold?

Describe what is occurring during repolarization. After repolarization there is a hyperpolarization that occurs. What causes the hyperpolarization?

Define graded potential. List the types of graded potential and the neurotransmitters that create them.

Describe the blood brain barrier. What is the advantage of this barrier?

In the condition multiple sclerosis, myelin is degenerated. Explain what happens to the action potential and why.

Describe how an action potential can be interrupted so neurotransmitter is not released from the presynaptic neuron.

Describe the neuromodulators and what effect they have on a synapse
