c) degree of myelination of the axon
Explanation:
Axon conduction velocity can be defined as the speed at which an electrochemical impulse propagates down an axon.
Factors that determines the rate of conduction velocity are:
- axon diameter-larger diameter axons have a higher conduction velocity
- sheeth-a myelin sheath increases the rate of impulse propagatio
Different types of neurons will have different speed of propagation because of their different properties and because different types of information are sent.
