Answer #1

The intial propagation is happens because of volatage gated Na+ channels and then Na+ ions can flow into cells along with their concentration gradints changing the the charge distribution and cause even bigger depolarigation inturn results in more Na+ channels to mopen incrrasing the Na+ permeability.

So all the option in given in question are right answer for it.

  • The resting membrane potential of a neuronal axon is -70 mV. When an action potential is...

    The resting membrane potential of a neuronal axon is -70 mV. When an action potential is triggered, Na+ ions move into the axon, which reverses the voltage, bringing it towards 0 mV. Which of the following is the correct term for this sequence of events? a. Repolarization b. Hyperpolarization c. Depolarization d. Hypopolarization e. Isopolarization

    During the propagation of an action potential, what would be the effect of a mutation in the voltage-gated Na+-channels that does not allow “inactivation” phase to occur, such that these channels go directly from open to closed conformations? a) The neuron with the mutant Na+ channels will start letting in calcium ions and generate a calcium-based action potential that is stronger than the sodium-based action potential. b) The neuron with the mutant Na+ channel will exhibit a reverse electrochemical gradient...

    In some cases, the excited membrane does not immediately repolarize after depolarization. Instead, the potential remains on a plateau near the peak of the spike potential for some milliseconds, then depolarization begins. This happens in the cardiac muscle fibers (0.2 to 0.3 second delay) due to what type of channels? Explain using the principle of all-or-nothing, absolute refractory period and the directionality of propagation of an action potential.

    8. Indicate whether the following lead to Depolarization OR Hyperpolarization (1) Opening of K+ channels on the post-synaptic membrane. (2) Opening of Cl- channels on the post-synaptic membrane. (3) Opening of Na+ channels on the post-synaptic membrane. 9. Indicate whether the following are Graded OR All-or-None responses. (1) Local potential (2) Action potential (3) EPSP (4) IPSP (5) End Plate Potential 10. True or False: Temporal summation of IPSPs increases the chance of having an action potential.

    QUESTION 35 Which of the following is NOT true regarding the propagation of action potentials O A. All of these statements are true B. The magnitude of the action potential stays the same as it travels down the axon. C. Voltage-gated Na+ channels open only when the threshold potential is reached. OD. Each segment of the axon prevents the adjacent segments from firing, E. The refractory period allows the impulse to travel in only one direction OF. None of these...

    If necessary, refer to Animation: Chemical Synapses. When an action potential reaches the axon terminal: sodium ions are released from the axon terminal, enter the cell body of the postsynaptic neuron through its sodium channels, and may initiate an action potential in that neuron. neurotransmitter molecules are released from the axon terminal and bind to receptors on the postsynaptic neuron, causing either an inhibitory hyperpolarization or an excitatory depolarization. neurotransmitter molecules are released from the axon terminal, bind to and...

    The reason why action potentials are described as "all or none" is: a. because neurotransmitter is released from all axon terminals or none of them. b. an action potential arriving at an axon terminal either causes all the neurotransmitters to be released or none to be released. c. either all ion channels in the axon membrane open or none open. d. if an action potential is generated in a neuron, the amplitude does not depend on the stimulus strength. e....

    ant Score: 10% Resources C Give Up? O Hint Check Answer of 10 Use the Action Potential Transmission tab of the Membrane Potentials interactive to help you answer the question. What would happen to the action potential transmission if voltage-gated sodium (Na+) channels in the initial axon segment were abnormally far apart from one another? The action potential would propagate more quickly than normal because saltatory conduction enables the depolarization signal to jump between voltage-gated Na+ channels. The action potential...
