Question

Which of the following is a factor that determines the rate of impulse propagation, or conduction velocity, along an axon?a) length of the axon b) the number of axon collaterals extending from a truncated axon c) degree of myelination of the axon d) whether the axon is located in the central nervous system or in the peripheral nervous system

Answer 1

Answer:

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.
