There are two properties that affect the conduction speed of an action potential along an axon

There are two properties that affect the conduction speed of an action potential along an axon: the axon's diameter and whether or not the axon is myelinated. Rank the axons from slowest to fastest conduction speed. If two axons have the same conduction speed, place one on top of the other.

Expert Solution

Fastest - myelinated vertebrate axon 30μm

Next - non-myelinated invertebrate axon - 40μm

Next - non-myelinated invertebrate axon - 30μm

Slowest - non-myelinated invertebrate axon -20μm.

The size of the axon and myelin insulation increase the speed of conduction of action potential.

Describe how an action potential propagates along a myelinated and an unmyelinated axon, including how the potential is spread along the membrane. How are these two processes similar and how are they different? What two benefits do myelinated axons have over unmyelinated ones? Provide one way in which a myelinated axon is similar to an electrical wire and one way in which an axon is different than a wire. Why does multiple sclerosis (MS) prevent transmission in myelinated axons (that...

Explain the need for saltatory conduction and how myelination and axon diameter affect rate of conduction – you can do this as an illustration. Make sure in your answer you include: axon, axon hillock, axon terminal, original action potential, new action potential, Schwann cell, myelin, node of Ranvier, depolarization, refractory DO NOT DEFINE THESE TERMS INDIVIDUALLY please type the answer.

When one action potential is traveling along an unmyelinated axon from cell body side and another...

When one action potential is traveling along an unmyelinated axon from cell body side and another action potential is traveling along the axon from synaptic terminal side, these two action potentials are going to collide with each other at the center of the axon. What is going to happen to these action potentials after the collision?
