- Which of the following would most likely occur if you experimentally depolarise the middle of an axon to threshold using an electronic probe? Question 24 options: an action potential will be initiated and proceed only in the normal direction toward the axon terminal no action potential will be initiated an action potential will be initiated and proceed only back toward the axon hillock two action potentials will be initiated and will proceed in opposite directionsWhat is action and resting potential and how does it work in conducting electrical impulses? Please provide an accurate and onpoint answer.Which of the following is/are true about action potentials? Select all correct asnwers. Group of answer choices always has the same amplitude (amount of depolarization) always has the same duration information is coded through the frequency of action potentials action potentials can sum toge
- Which of the following combinations of spatial summation of postsynaptic potentials (PSP) would result in an action potential in a typical neuron? The voltage given for each PSP is measured as it reaches the axon hillock. Axon A EPSP 25 mV & axon B IPSP 10 mV Axon A IPSP 25 mV & axon B EPSP 10 mV Axon A IPSP 5 mV & axon B IPSP 5 mV Axon A EPSP 5 mV & axon B EPSP 5 mVBecause the long axons of neurons look like electrical wires, and both neurons and electrical wires conduct electricity, it is tempting to equate the two. Compare and contrast the functioning of axons and electrical wires in terms of their structure and the nature of the electrical signals they conduct. Please include references.Can you explain to me why choice E is the correct answer and break down why the other options are false?Select the choice option that is TRUE regarding the absolute and relative refractory periods of the action potential (AP). A. The absolute refractory period occurs when the activation gate of voltage gated sodium channel closes at the peak of the AP B. The relative refractory period occurs when the inactivation gate of voltage gated sodium channels closes at the peak of the AP C. The relative refractory period occurs when the activation gate of voltage gated potassium channels opens at the peak of the AP D. The absolute refractory period may be overcome if enough excitatory stimulation is applied to the neuronal membrane E. All of the choice options are FALSE regarding the absolute and relative refractory periods of the AP
- Summarize the steps in generating an action potential as a flowchart. You can make your flowchart on paper and take a picture of it, or make it electronically. Be sure you’ve included: the location in the neuron and components of the neuron involved, the types of cellular transport and ions involved, how action potentials can be stimulated and inhibited. you can get the information from this: https://youtu.be/HYLyhXRp298I am confused about the process of rod cells in the dark. In the dark, rod cells are unstimulated and therefore the sodium is able to enter and depolarize the cell, stimulating the release of glutamate to the bipolar cell. However, this increase in glutamate in the bipolar cell inhibits the release of action potential from the bipolar cell to the ganglion cell. This doesn't make sense to me because shouldn't there be an increase in action potential since the rod cells are supposed to function in the dark?Which of the following is true regarding the difference between graded and action potentials? a.) Action potential occur only when the surface of the neuron is myelinated, but graded potentials occur in both in both myelinated and non-myelinated neurons. b.) The magnitude of action potential depends on the magnitude of the stimulus, whereas graded potentials are all or none. c.) The magnitude of graded potential depends on the magnitude of the stimulus, whereas action potentials are all or none.
- Which of the following can increase the likelihood of a neuron generating an action potential? tetrodotoxin (TTX) reducing the external concentration of K+ decreased diffusion of K+ through leak channels out of the neuron All of the aboveIn the laboratory, researchers can apply an electrical stimulus at any point along the axon, making action potentials travel in both directions from the point of stimulation. An action potential moving in the usual direction, away from the axon hillock, is said to be traveling in the orthodromic direction. An action potential traveling toward the axon hillock is traveling in the antidromic direction. If we started an orthodromic action potential at the axon hillock and an antidromic action potential at the opposite end of the axon, what would happen when they met at the center? Why?An action potential has reached the axon terminal of a presynaptic cell. As a result of the action potential you would expect the movement of __________ into the presynaptic cell and the movement of __________ out of the presynaptic cell.
