Question

axon conduction unmyelinated axons

- The size or magnitude of APs remains constant but frequency changes AXON COND NO. - Neurons are dynamically the main dendrites and then to the signals , so that information flows from the fine dendrites into where it is converted into APs are relayed to other neurons by the axon, a long wire-like structure. -APs get all along the length of the axon from Na+/K+ pumps and gates - Nat rush into the neurons from the ECF, resulting i a transient change in the voltage difference across the PM. When an AP occurs in an axon the depolarization is axon, restricted to just one region of the - The AP travels like dominos falling from the cell body down the length of the neuron. - The AP enables the neuron to communicate rapidly with other neurons over sizable distances, sometimes more than a meter away with speeds of 20-200 m/sec Unmyelinated Axons - After reaches and fires its Na+ influx depolanizes adjacent regions to threshold and generates a new Ap -Process repeats all along axon (wave) -AP is always same -Increase diameter will ncrease speed

Explanation / Answer

Ans. Neurons are dynamically selective, so that information flows from the fine dendrites into the main dendrites and then to the axon, where it is converted into electrochemical signals.

AP's get transmitted along a myelinated axon, all along the length of the axon from Na/K pumps and gates.
