The major role of the Na+/K+ pump is to: a. cause a rapid firing of the action potential so the inside of themembrane becomes momentarily positive. b. decrease the resting membrane potential to zero. c. hyperpolarize the membrane above resting value. d. cause an action potential to enter a refractory period. e. maintain the resting membrane potential at a constantnegative value.
How much of a change in the membrane potential is necessary for the summation of postsynaptic potentials to result in an action potential being generated? +30 mV +15 mV +10 mV -15 mV
Watch this video (http://openstaxcollege.org/l/3Dmovies) to learn about the side effects of 3-D movies. As discussed in this video, movies that are shot in 3-D can cause motion sickness, which elicits the autonomic symptoms of nausea and sweating. The disconnection between the perceived motion on the screen and the lack of any change in equilibrium stimulates these symptoms. Why do you think sitting close to the screen or right in the middle of the theater makes motion sickness during a 3-D movie worse?
Which of the following voltages would most likely be measured during the relative refractory period? +30 mV 0 mV -45 mV -80 mv
Please ASAP. Thanks Ion Extracellular Concentration (mM) Intracellular Concentration (mM) Na+ 440 50 K+ 20 400 Cl- 560 52 Ca++ 10 1 What is the effect of the addition of extracellular TTX and TEA on equilibrium potential? TTX blocks K channel, and TEA blocks Na Channels. No change in the equilibrium potentail. TTX blocks Na channel and TEA blocks K Channels. The equilibrium potentials become less positive TTX blocks Na channel and TEA blocks K Channels. The equilibrium potential becomes more positive for both TTX blocks Na channel and TEA blocks K Channels. No change in the equilibrium potentail. TTX and TEA blocks Na channel. No change in the equilibrium potentail.
A muscle cell contains acetylcholine receptors that act as ligand-gated cation channels,and it also contains voltage-gated Na+ channels of the type found in neurons. Intheory, could a muscle cell get away with having only acetylcholine-gated cationchannels, which would serve the dual purpose of receiving neurotransmitter signalsand propagating action potentials? Why or why not?

1.) In an experiment you artificially cut in half (~50% reduction) the number of voltage gated sodium channels that are located on the membrane of the axon hillock. Which of the following is the most likely result of this experimental manipulation? A. Summation of more IPSPs would be required for an action potential to occur B. This change would have no effect on the value required to reach threshold C. Even with a very large number of summating EPSPs it would be impossible for an action potential to occur D. The value to reach threshold would be higher (more positive) making it less likely for an action potential to occur E. All of the above statements are FALSE
