When you look at the cord coming out of the lamp on your desk, you will notice that there is a protective coating that surrounds and encapsulates the electricity-conducting wire inside. If you were to relate that model to the human neuron, the protective coating would refer to the
A) terminal buttons.
B) synaptic cleft.
C) neurotransmitters.
D) myelin.

Quizplus · Accepted Answer

The protective coating surrounding the wire in a lamp cord is analogous to the myelin sheath that surrounds and protects the axons of neurons. This coating helps to insulate the wire and prevent electrical signals from escaping or interfering with other signals. Similarly, the myelin sheath helps to insulate the axon and increase the speed and efficiency of electrical signals traveling through the neuron. The other options (terminal buttons, synaptic cleft, and neurotransmitters) are all involved in different aspects of neural communication and are not directly related to the protective coating around a wire.
