Which of the following statements regarding postsynaptic potentials is correct? IPSPs are the result of influx of potassium ions and EPSPs are the result of efflux of sodium ions. IPSPs are the result of efflux of potassium ions and EPSPs are the result of influx of chloride ions. IPSPs are the result of efflux of potassium ions and EPSPs are the result of influx of sodium ions. IPSPs are the result of efflux of chloride ions and EPSPs are the result of efflux of calcium ions.

starting with an axon that is maintaining a resting potential, describe the sequence of events that causes the generation of an action potential, including the electrical charges and ions involved.

Nicotinic acetylcholine receptors allow both sodium and potassium to flow across the cell membrane when the receptors are activated. Which statement is true about the flow of ions through nicotinic receptors? Potassium only flows through an open nicotinic receptor only when there is no sodium present. More sodium ions pass through an open nicotinic receptor than pass potassium ions. An equal number of sodium and potassium ions pass through an open nicotinic receptor. O More potassium ions pass through an open nicotinic receptor than pass sodium ions.

Order the following in the correct sequence that results in generation of action potential local potential is generated at axon hillock action potential may or may not result in subsequent post synaptic neuron depending on type of neurotransmitter and receptors etc. stimulus is picked up by dendrites If the potential reaches a threshold, action potential spreads throughout the axon signal then reaches synaptic knob, which releases neurotrasmitters A Moving to another question will save this response. « < Question 51 17 étv 80 DII DD F2 F3 F4 F5 F9 F10 23 24 2 3 4 5 6 7 8. 10 R T Y S.
