Why does this increase the likelihood of an action potential?  

Myelination in the central nervous system is accomplished by which type of cell? 

Use the given diagram to answer the following question. At which points on the diagram is potassium permeability increased compared to rest?

Damage to white matter would mostly affect _______  while damage to gray matter would affect ________. 

A cell has a total membrane potential of -70mV; Cation A is found in both the ECF and ICF, and has an equilibrium potential of +45mV; Cation B is found in both the ECF and ICF, and has an equilibrium potential of -85mV Identify each statement as true or false.

The patient’s right-sided weakness is most directly explained by damage to which structure? 

Scenario 4 A neuron receives an EPSP on its dendrites and an IPSP near the axon hillock.  

Which additional clinical finding would most likely be associated with this patient’s condition? 

Reflex action is controlled by the: 

Scenario 1 A membrane separates two compartments and is permeable only to potassium (K⁺).   [K⁺] outside = 3.8 mM   [K⁺] inside = 112 mM
