Exam 3: Neurophysiology: the Structure and Functions of the Cells of the Nervous System

Which of the types of cytoskeleton fiber run the length of axons,providing structural support for the cell? 

Extracellular fluid is rich in​ 

Additional action potentials can occur in response to stronger-than-normal stimulation during a neuron's absolute refractory period.

Presynaptic facilitation occurs at a synapse between a presynaptic axon and a postsynaptic dendrite,and leads to more frequent signaling by the postsynaptic cell.

The resting potential of a neuron is primarily dependent on the movement of 

Neurons with short axons that communicate primarily with adjacent cells are known as _________ neurons.​ 

Proteins produced in the cell body are packaged by the 

Abnormalities involving which type of cytoskeleton fibers have been implicated in Alzheimer's disease? 

Protein structures on the postsynaptic neuron that have recognition sites on the extracellular side and G proteins on the intracellular side are known as 

In the resting neuron,sodium is pushed 

What are three major similarities and differences between oligodendrocytes and Schwann cells?

One very active synapse might lead to an action potential in a postsynaptic cell due to 

In vertebrates,unipolar cells are common in the 

In a healthy brain,adjacent microtubules are connected by 

In order to understand the way the brain and nervous system function,it is important to remember that 

Which type of glia actually helps guide the regrowth of axons following injury? 

The tendency for molecules to distribute themselves equally within a medium is known as 

The tendency for molecules with like signs to move apart and molecules with opposite signs to move together is known as 

Ion selectivity is a feature of 

When we find large numbers of mitochondria in a location,what can we infer about the processes that are occurring there?
