One purpose of the __________ is to speed up the neural message traveling down the axon.
A) receptor site
B) axon terminal
C) myelin
D) synaptic vesicle
Myelin
A fatty substance that surrounds and insulates the axons of some neurons, enhancing the speed and efficiency of electrical impulse transmission.
Neural Message
Information transmitted within the nervous system, typically in the form of electrical and chemical signals across neurons.
Axon
A long, slender projection of a neuron that transmits electrical impulses away from the neuron's cell body to other neurons or to muscles or glands.

Final Answer :
C
Explanation :
Myelin acts as an insulating sheath around the axon, which speeds up the neural message by allowing it to skip the depolarization and repolarization process at each segment of the axon.
