Document Summary

From leaking out action potential conduction or velocity at which the depolarization is pushing forward / rate is controlled myelinated sheets wrapped around axon. Ap will be regenerated a t each node. Saltatory conduction : the ap ships / jumps from node +0 node. Internodial myiination by the amount of nat channels ( the more nat that flows in and bounces off kt gives a higher rate and faster they will push forward. Review : nat / tht pomp two forces that determine conduction velocity conduction velocity : the rate. * bi = thveiocity the lower the resistance the faster the velocity (cid:8869) how low the resistance is determined by the diameter of the axon. * the larger the axon the lower the internal resistance. * the larger the axon the faster the conduction velocity ( in invertebrates like squid ) Pam : membrane resistance 4 rm = av.
