Message transmission at the end of the axon is dependent upon the functioning of the:

a. terminal button.
b. myelin sheath.
c. dendrite.
d. nucleus.

is it B



The neurobiologist explained to the students, "The neural system is very much like the wires connecting your T.V. and stereo to the electrical outlet. If the wires were not covered with insulation, the signal would short circuit." The neurobiologist was describing the function of the:

a. terminal button.
b. axon.
c. inhibitory system.
d. myelin sheath.

im confused between D and C

No. What word in your choices would essentially mean end?

What is the function of the myelin sheath?

For the first question, the correct answer is B. The functioning of message transmission at the end of the axon is indeed dependent upon the myelin sheath. The myelin sheath is a protective covering made up of fatty substances that wraps around the axon. It acts as insulation, allowing the electrical signals to travel more efficiently along the axon.

For the second question, the correct answer is D. The neurobiologist's analogy of comparing the neural system to wires connecting a T.V. or stereo to an electrical outlet is describing the function of the myelin sheath (answer D). Just like how the insulation on the wires prevents signals from short-circuiting, the myelin sheath insulates the axon, helping to maintain the integrity of the electrical signals traveling through it. The inhibitory system (answer C) is not relevant to the analogy mentioned.
