WebOct 11, 2024 · Since the myelin sheath surrounds the axon, one of its functions is to separate the axon from surrounding extracellular components. Its main function, however, … WebOct 11, 2024 · Its main function, however, is to insulate the axon and increase the velocity of action potential propagation. Myelin has properties of low capacitance and high electrical resistance which means it can act as an insulator. Therefore, myelin sheaths insulate axons to increase the speed of electrical signal conduction. truman thomas truman thompson virginia beach

WebAn action potential is an event that is specific to excitable cells like neurons or muscle fibers. It involves a rapid and short-lasting rise in the electrical potential, immediately … WebApr 21, 2024 · Why does an action potential travel in one direction down an axon quizlet? The refractory period is a crucial feature of neural signaling because it restricts the pace at which action potentials may be produced. Furthermore, the refractory time allows for unidirectional action potential propagation along the axon.
