stuck please help I'm so lost on these things

The size or magnitude of APs remains constant but frequency changes AXON CONDUCTION: - Neurons are dynamically the main dendrites and then to the signals - APs are relayed to other neurons by the axon, a long wire-like structure. - APs get so that information flows from the fine dendrites into where it is converted into all along the length of the axon from Na+/K+ pumps and gates - Nat rush into the neurons from the ECF, resulting in a transient change in the voltage difference across the PM. When an AP occurs in an axon the depolarization is restricted to just one region of the axon. 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 its Na+ reaches and fires - After influx depolarizes adjacent regions to threshold and generates a new AP - Process repeats all along axon (wave) -APis always same - Conduction is - Increase diameter will increase speed

Explanation / Answer

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

Aps get generated all along the length of the axon Na+/K+ pumps and gates.

Unmyelinated axons

After action potential reaches at synapse and fires neurotransmitter release(stimulus), its Na+ influx depolarizes adjacent regions to threshold and generates a new Ap.

AP generation is always same.

Conduction is slower in unmyelinated axons.
