    Action Potential/Myelination

    I have a sort of stupid question. I had this pretty simple question on an exam and it has been bothering me ever since. True or False: Myelination increases the speed of an action potential. Now, if the question stated, “Myelination increases the conduction speed of an action potential”, I...
