2 I. PROPAGATION OF A.P. Figure 48.14 A. Propagation • Video action potential propagation I. PROPAGATION OF A.P. B. No back propagation of A.P. because: 1) Voltage-dependent K+ channels 2) A.P. starts from cell body 3) Refractory Period Recovery time for Na+ channel (like dominos, all or none event) C. A.P. Velocity 1) Max. 120 m/sec 2) Saltatory Conduction: A.P. jumps to nodes of Ranvier
