Step by step
Solved in 3 steps
- 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/HYLyhXRp298Describe the events that occur during action potential ANSWER SHOULD INCLUDE: Explanation of how resting membrane potential works and which ions inside/outside Expiation of how depolarisation membrane occurs and which ions move in/how they move in . Explanation of "threshold" . Explanation of depolarisation and which ions move out and how they move out. Explanation of hyperpoarisation and how it is corrected. ( state membrane potential in mv during each stage )Describe the resting potential for neurons. How is this potential established? Describe the development of the action potential. How does this come about, and what is the function of this phenomenon?

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 togeExplain the time course of the opening and closing of v-g Na+ and K+ channels during the action potential. How does that affect the ionic currents? COMMENTS : answer this question to best of your knowledge to understand the concept wellTemporal summation refers to: summation of action potentials in the temporal cortex. summation of postsynaptic potentials on a neuron occurring closely together in time. summation of postsynaptic potentials at different places on a neuron at the same time. summation of postsynaptic potentials in the temporal cortex.

- What is the difference between an action potential and a synapse? (select all that apply) The action potential moves down the axon and a synapse is between neurons. The synapse travels long distances and the action potential can only travel short distances. The action potential starts at the dendrites and the synapse starts at the ахon. The action potential is always the same and the synaptic potentials vary. the action potential involves only the postsynaptic neuron, but the synapse involves both the pre- and post-synaptic neurons.what is the correct orderMatch the stages of action potential with the appropriate image or description. 1. Resting membrane potential 2. Threshold 3. Depolarization 4. Repolarization 5. Hyperpolarization 6. Refractory period The potential difference that must be met in order for an action potential to be generated When the potential drops below resting level When the potential starts to decrease again after it has reached a maximum Occurs at -77 mV When the membrane is resetting and an action potential cannot yet be produced again When the sodium channels are open Occurs at -55 mV
