The soma is the main site of ________ in the neuron.
|
Integration.
|
|
How do neurons communicate with one another?
|
Chemical signals.
|
|
How is an action potential propagated throughout a single neuron?
|
Chemical signals.
|
|
Which is analogous to an electrical capacitor in a cell membrane?
|
Lipid bilayer.
|
|
At rest, a cell’s membrane potential is
|
Negative on the inside of the cell.
|
|
What is the major determinant of the potential of a membrane in a standard electrolytic medium?
|
Selective permeability of different ions across the membrane
|
|
What is an equilibrium potential?
|
The membrane potential at which a solute will be at equilibrium. For each ion, the equilibrium (or reversal) potential is the membrane potential where the net flow through any open channels is 0.

|
If the equilibrium potential for K+ is -58 mV, which is true of K+ at a membrane potential of 0 mV? (assume that the membrane is permeable to K+)
|
K+ should diffuse out of the cell
