Communication with Neurons

Neural communication involves different processes within and between neurons. In this infographic, we follow the electrical action that conveys messages within the neuron, from one end to the other.

1.1 Quiz

1. If you were to measure the electrical potential of a neuron when it is not in a firing state – when it is basically “at rest,” – what sort of charge would you find?

A.
B.
C.
D.

Correct.
Incorrect.

2. Jimmy is standing in line at a nightclub one evening, waiting to get in. He notices that the doorman is letting in all of the women in line, and the men are all being made to wait. After a while, the entire inside of the club is full of women, and the outside has only men. If this situation was analogous to a neuron in its resting state, which of the following would be an accurate statement?

A.
B.
C.
D.

Correct.
Incorrect.

3. Sebastian is taking an Introduction to Psychology course, and is completing some online video simulations to understand how a neuron works. This particular video shows a neuron converting from its resting state to its action potential. It happens when the charge inside the neuron reaches around -55 mv. This boundary between the two states of the neuron is called its ________.

A.
B.
C.
D.

Correct.
Incorrect.

4. What happens to a neuron after it completes its action potential?

A.
B.
C.
D.

Correct.
Incorrect.

5. If you think about an action potential as being similar to running a marathon, it would have a Start line and a Finish line. Which of the following would represent each of those positions?

A.
B.
C.
D.

Correct.
Incorrect.

6. Jared is driving down the highway, and is paying attention to the broken line that separates the different lanes. He thinks “those gaps in the lines create spaces every few feet. That sort of reminds me of the gaps in the myelin sheath that surrounds the axon in a neuron.” What are the gaps in the myelin sheath that Jared is thinking of called?

A.
B.
C.
D.

Correct.
Incorrect.
