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...
