Longitudinal Resistance i. ____ (Inc/Dec) in diameter will increase longitudinal resistance, and therefore _____ (Inc/Dec) conduction velocity. b. Membrane Conductance i. ____ (Inc/Dec) in the amount of myelin will decrease membrane conductance, and therefore ____ (Inc/Dec) conduction velocity. II. Types of Fibers a. A i.

Gamma – primarily used for ___________________________________. iv. Delta – primarily used for _____________________________________. *Not integral to memorize diameter of these, just know how the x-sectional area and conduction affects conduction velocity* b.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
