LIFSCI 7B XL - Animation: Reading Phylogenies Copy Questions and Answers Rated A+ What is the role of the axon hillock in neural signaling? The axon hillock integrates incoming signals and determines whether to initiate an action potential. How does myelination affect the speed of action potential propagation along an axon? Myelination increases the speed of action potential conduction by enabling saltatory conduction, where the signal jumps between nodes of Ranvier. Why do vo...
