Nervous system question

[virtualmaster999]

Hey all!

Can someone tell me if I'm getting this down right?

So for action potentials: inc the stimulus results in an increased frequency of action potentials, while the size/ speed is constant.

For a nerve impulse, the movement of an AP along a nerve fiber, increasing the diameter, or myelinating the axon increases the speed.

Is this all right?

Thanks in advance!

Looks correct to me.

from the article:
2) The larger the diameter of the nerve fiber, the faster the conduction velocity.

I believe action potentials and nerve impulses are the same thing. But you are right. The intensity of the stimulus affects the frequency of the action potential while the characteristics of the axon (diameter, myelination/nodes, etc) affect the speed of the action potential.
