Please post two discussion questions by our Monday Live Session to cultivate our discussion. ]]> 2021-03-27 06:02:44 UTC https://padlet.com/mdodda/qsj8rnxtifsk5ag6/wish/1359465712 mdodda https://padlet.com/mdodda/qsj8rnxtifsk5ag6/wish/1359466865 Here are the objectives for this chapter, just so everyone knows where we are headed: 

1. Distinguish among the following sets of terms: sensory neurons, interneurons, and motor neurons; membrane potential and resting potential; ungated and gated ion channels; electrical synapse and chemical synapse; EPSP and IPSP; temporal and spatial summation
2. Explain the role of the sodium-potassium pump in maintaining the resting potential
3. Describe the stages of an action potential; explain the role of voltage-gated ion channels in this process
4. Explain why the action potential cannot travel back toward the cell body
5. Describe saltatory conduction
6. Describe the events that lead to the release of neurotransmitters into the synaptic cleft
7. Explain the statement: “Unlike action potentials, which are all-or-none events, postsynaptic potentials are graded”
8. Name and describe five categories of neurotransmitters

Figures 48.7 and 48.11 might help.]]> 2021-04-26 05:53:59 UTC https://padlet.com/mdodda/qsj8rnxtifsk5ag6/wish/1457993465 lmoscola https://padlet.com/mdodda/qsj8rnxtifsk5ag6/wish/1458016123 What are Schwann cells? How do they help organisms react more quickly? I did a bit of research, and found that Schwann cells on the same axon always have very similar widths and lengths, with maximized shape for the diameter of the axon they are on. Why do you think this is, and how do you think it occurs?]]> 2021-04-26 06:02:24 UTC https://padlet.com/mdodda/qsj8rnxtifsk5ag6/wish/1458016123 hschechter1 https://padlet.com/mdodda/qsj8rnxtifsk5ag6/wish/1460163543 Why can neurons only deliver one intensity of an electric pulse?]]> 2021-04-26 15:42:26 UTC https://padlet.com/mdodda/qsj8rnxtifsk5ag6/wish/1460163543 sgutwein https://padlet.com/mdodda/qsj8rnxtifsk5ag6/wish/1460201653 It's really interesting that post-synaptic potentials can build on and detract from one another, especially compared to action potentials. How might this have evolved in an evolutionary sense? As in, what is the evolutionary benefit to this fact?]]> 2021-04-26 15:49:10 UTC https://padlet.com/mdodda/qsj8rnxtifsk5ag6/wish/1460201653 sgutwein https://padlet.com/mdodda/qsj8rnxtifsk5ag6/wish/1460222153 Draw a neuron and label its parts. ]]> 2021-04-26 15:52:54 UTC https://padlet.com/mdodda/qsj8rnxtifsk5ag6/wish/1460222153 hschechter1 https://padlet.com/mdodda/qsj8rnxtifsk5ag6/wish/1460248616 Communication in the brain is dependent on electrical pulses and waves, which can be seen through things like EEGs. Keeping your knowledge of neurons and the brain in mind, how would things like ECT or seizures work?]]> 2021-04-26 15:57:53 UTC https://padlet.com/mdodda/qsj8rnxtifsk5ag6/wish/1460248616
