Question

The importance of a neuron's structure in action potential propagation Task: To successfully complete this assignment you should read Garrett, B. & Hough, G. (2018). Chapter 2: Communication within the nervous system. In Brain and behavior: An introduction to behavioral neuroscience (5th ed) (pp. 20-30). Los Angeles, CA: Sage., watch the cells of the nervous system video, answer the following questions about the presented material, and type your responses in a document. Your answers should then be uploaded to this assignment on Canvas as a .doc, .docx, or pdf file. Your picture or diagram can be hand-drawn and a photograph or scan of this can be uploaded as a separate document. Two points will be deducted for every calendar day that the assignment is late (past due date). 1. Draw a picture ions during the neuron's resting state. This picture symbolic or cartoonish) and should be more than a copy of a figure from your textbook or a website. or create a diagram of a neuron at rest. Your diagram or picture should reflect the location of diagram does not need to be realistic in nature (can be or 2. Describe what force of diffusion and electrostatic pressure are. 3. We know that ions must move to generate an action potential. We also know where ions are located at rest (see answer 1) and what laws govern the movement of ions across a membrane if movement is not restricted (see answer 2). The other rule here is that the negatively charged proteins are too large to leave the neuron. Based on these rules, which ions do youexpect to move and where in order to generate the depolarization that occurs in the first part of an action potential?
