Question 1 1 pts Using the data provided in the table below for an "average" axon, we found in the previous lab and in the pre-lab questions for this lab) that the membrane resistance and membrane capacitance were about 44MS2 = 44 x 102 and 60pF = 60 x 10-12 F, respectively, for a membrane segment of length 0.73 mm. Typical values for a neuron under average conditions Axon radius (r) 5x10m Membrane thickness (1) 1x10 m Axoplasm resistivity (pa)...

Question 3 1 pts Many nerves, for example, motor neurons used in muscle contraction, are wrapped in myelin, a sheath of repeated units of lipid bilayers and proteins. The effect of myelin is to reduce the amount of ions leaking out the membrane, which therefore reduces the degree of amplification of a signal required during de- and repolarization, and, hence, increases the voltage signal speed. With regard to our model circuit, a myelinated axon simply can be represented by an...

1. An average nerve axon is about 5x10-6m in radius, and the axoplasm that composes the interior of the axon has a resistivity of about 2 Ω ⋅m. What is the resistance of just 2-cm length of this axon? Provide your answer in mega-ohms (1 mega-ohm = 106 ohms or "millions of ohms"). (Note, this value is so large -- it corresponds to the resistance of tens of thousands of miles of the thinnest copper wire normally manufactured(!) -- that it...

12:57 Exit D Question 5 1 pts Myelination occurs quickly in humans during infancy, leading, e.g., to a child's fast motor development (crawling, walking -- those toddlers can move!) as the speed of voltage pulses through their neurons increases with myelination of those nerve fibers. However, there are a number of neurodegenerative diseases, such as multiple sclerosis and Guillain- Barre syndrome (which they mention when you get your flu shot), in which demyelination (loss of the myelin sheath insulating the...

Question 4 1 pts A physics student records the data in the table below during a 1-D motion experiment with constant acceleration. Unfortunately he forgets to properly label the table before emailing it to his lab partners for analysis. As a result, they have to use their knowledge of kinematics to figure out how the table is organized and what the rows and columns represent. Use your knowledge of kinematics to select the correct answer below. Assume that all units...
