HUBS1416 Practice Exam Questions and Answers Which of the following would be expected to inhibit the generation of an action potential? a) Inflammation of the myelin sheath b) Stimulating GABA receptors c) Blocking acetylcholine receptors d) Activating adrenalin receptors -Answer-b) Stimulating GABA receptors Which is true about neurons? a) At rest a neuron will have a negative membrane potential, due to it having more open K+ channels than Na+ channels b) Inhibitory neurons will relea...

AQA A Level Biology : Year 2- Nervous Coordination Graded A What is the value of the resting potential of a neurone? Why is the resting potential of a neurone negative? -70mV There are more positive ions outside the cell than inside How is the resting potential maintained? actively transports 3 Na+ out for ever 2 K+ into the neurone (ATP Hydrolysed) Sodium-potassium pump Membrane more permeable to K+ and less permeable to Na+ What happens if the sodium ion channels rema...
