Myelinated Axon: A myelinated axon has a fatty substance called myelin surrounding it, which speeds up signal transmission.
Saltatory Conduction: This term refers to how electrical signals "jump" from one node of Ranvier (unmyelinated gap) to another along a myelinated axon, allowing for faster conduction.
Action Potential:The brief electrical impulse that travels down an axon when it reaches the threshold level of excitation.
