INFORMATION ABOUT IMAGE G FOR QUESTIONS 12-15:
GABAB receptors (GABABRs) are
G-protein-coupled receptors that can be found on both pre- and
postsynaptic neurons. When they are activated by GABA, they can
have a range of effects. For the synapse you are studying in the
following questions, the effects of GABABRs are
indicated in IMAGE G.
You are doing a series of experiments in which you are recording
from the pre- and postsynaptic cell at a synapse. The experiments
described below...

Consider the following for problems 1 through 5: The concept of electric potential difference plays an important role in the human nervous system. A nervous impulse, for example, is an action potential that results from the temporal rising and lowering of the cell membrane potential, which in turn is caused by the equally temporal influx of sodium (Na+) ions into the cell. The sodium ions enter the cell through Hodgkin-Huxley channels, named after English physiologist/biophysicists Alan Hodgkin and Andrew Huxley....

Question 3 1 pts Many nerves, for example, motor neurons used in muscle contraction, are wrapped in myelin, a sheath of repeated units of lipid bilayers and proteins. The effect of myelin is to reduce the amount of ions leaking out the membrane, which therefore reduces the degree of amplification of a signal required during de- and repolarization, and, hence, increases the voltage signal speed. With regard to our model circuit, a myelinated axon simply can be represented by an...
