Chapter 01 The Cellular Foundations of Behavior
True / False
1. Our universe has equal amounts of matter and antimatter.
a. True
b. False
ANSWER: False
RATIONALE: The Big Bang that started the universe contained an as-yet unexplained asymmetry that
caused the development of more matter than antimatter. If matter and antimatter had been
equal, there could be no stars, planets, or anything else.

State the mind–brain problem and contrast monism with dualism.
2. When you see something, you send sight rays out of your eyes.
a. True
b. False
ANSWER: False
RATIONALE: When you see something, the experience is in your head, not “out there.” You do not send
“sight rays” out of your eyes, and even if you did, they wouldn’t do you any good.
DIFFICULTY: Easy
LEARNING OBJECTIVES: BIPS.KALA.24.01.02 - List three points that are important to remember from this text.

system.
7. Santiago Ramón y Cajal used special staining techniques to show that the brain is composed of individual cells.
a. True
b. False
ANSWER: True
RATIONALE: Spanish investigator Cajal used Golgi’s staining method, but he applied it to infant brains, in
which the cells are smaller and easier to examine on a single slide. He came to the
conclusion: Nerve cells remain separate instead of merging into one another.
DIFFICULTY: Easy

mitochondria from your biological mother, who got them from her mother, and so on.
DIFFICULTY: Medium
LEARNING OBJECTIVES: BIPS.KALA.24.01.05 - Describe neurons and glia, the cells that constitute the nervous
system.
11. Dendrites contain the nuclei, ribosomes, mitochondria, and other structures found in most cells.
a. True
b. False
ANSWER: False
RATIONALE: The cell body, or soma (Greek for “body”; plural: somata), contains the nucleus, ribosomes,
and mitochondria.
DIFFICULTY: Medium
LEARNING OBJECTIVES: BIPS.KALA.24.01.06 - Contrast axons with dendrites.
12. Glia have dendrites and axons.
a. True
b. False
ANSWER: False
RATIONALE: Glia (or neuroglia), the other components of the nervous system, perform many functions
(Figure 1.15). The term glia, derived from a Greek word meaning “glue,” reflects early
investigators’ idea that glia served a function like glue, to hold the neurons together.
DIFFICULTY: Medium
LEARNING OBJECTIVES: BIPS.KALA.24.01.05 - Describe neurons and glia, the cells that constitute the nervous
system.
13. Neurons are distinguished from other cells by their shape.

17. It is possible to describe the same axon as both afferent and efferent.
a. True
b. False
ANSWER: True
RATIONALE: Within the nervous system, any neuron is an afferent from one structure and an efferent to
another.
DIFFICULTY: Medium
LEARNING OBJECTIVES: BIPS.KALA.24.01.06 - Contrast axons with dendrites.
18. Astrocytes synchronize the activity of a group of neurons.
a. True
b. False
ANSWER: True
RATIONALE: By surrounding a connection between neurons, an astrocyte shields it from chemicals
circulating in the surround (Nedergaard and Verkhatsky, 2012). Also, by taking up
the ions and transmitters released by axons and then releasing them back, an astrocyte
helps synchronize closely related neurons, enabling their axons to send messages in
waves.

system.
21. Schwann cells and oligodendrocytes produce myelin.
a. True
b. False
ANSWER: True
RATIONALE: Oligodendrocytes (OL-i-go-DEN-druh-sites) in the brain and spinal cord and Schwann cells
in the periphery of the body build the myelin sheaths that surround and insulate certain
vertebrate axons.
DIFFICULTY: Medium
LEARNING OBJECTIVES: BIPS.KALA.24.01.05 - Describe neurons and glia, the cells that constitute the nervous
system.
22. The blood–brain barrier is made up of closely packed glial cells.
a. True
b. False
ANSWER: False
RATIONALE: The blood–brain barrier (Figure 1.17) depends on the endothelial cells that form the walls of
the capillaries (Bundgaard, 1986; Rapoport and Robinson, 1986). Outside the brain, cells
along the capillaries are separated by small gaps, but in the brain, they join so tightly that
they block almost anything from passage.
DIFFICULTY: Medium
LEARNING OBJECTIVES: BIPS.KALA.24.01.07 - Summarize how the blood–brain barrier relates to protection and
nutrition of neurons.
23. The brain uses more energy and oxygen than all other organs combined.

27. Sodium ions are always more concentrated outside a neuron membrane than inside.
a. True
b. False
ANSWER: True
RATIONALE: Sodium ions are more than 10 times more concentrated outside the membrane than inside.
DIFFICULTY: Medium
LEARNING OBJECTIVES: BIPS.KALA.24.01.12 - Discuss how the movement of sodium and potassium ions produces
the action potential and recovery after it.
28. The resting potential of the neuron membrane prepares it to respond rapidly to a stimulus.
a. True
b. False
ANSWER: True
RATIONALE: The resting potential prepares the neuron to respond rapidly. Excitation of the neuron opens
sodium channels, letting sodium enter the cell rapidly. Because the membrane did its work in
advance by keeping so much sodium outside, the cell is prepared to respond vigorously to a
stimulus.
DIFFICULTY: Medium
LEARNING OBJECTIVES: BIPS.KALA.24.01.12 - Discuss how the movement of sodium and potassium ions produces
the action potential and recovery after it.
29. An axon indicates the strength of a stimulus by altering the amplitude or velocity of its action potentials.
a. True
b. False
ANSWER: False
RATIONALE: The all-or-none law constrains how an axon can send a message. To signal the difference
between a weak stimulus and a strong stimulus, all that an axon can change is the frequency
of its action potentials, or their timing.

LEARNING OBJECTIVES: BIPS.KALA.24.01.13 - State the all-or-none law of the action potential.
30. The all-or-none law applies to both axons and dendrites.
a. True
b. False
ANSWER: False
RATIONALE: An action potential starts in an axon and propagates without loss from start to finish.
However, at its start, it “backpropagates” into the cell body and dendrites (Lorincz and
Nusser, 2010). The cell body and dendrites do not conduct action potentials, but they
passively register the electrical event that started in the nearby axon.
DIFFICULTY: Medium
LEARNING OBJECTIVES: BIPS.KALA.24.01.13 - State the all-or-none law of the action potential.
31. Local anesthetic drugs such as Novocain block pain by attaching to sodium gates in the neuron membrane.
a. True
b. False
ANSWER: True
RATIONALE: Local anesthetic drugs, such as Novocain and Xylocaine, attach to the sodium channels of the
membrane, preventing sodium ions from entering. When a dentist administers Novocain
before drilling into one of your teeth, receptors in your teeth scream, “pain, pain, pain!” but
the axons cannot transmit the message to your brain, and you don’t feel it.
DIFFICULTY: Medium
LEARNING OBJECTIVES: BIPS.KALA.24.01.15 - Describe the importance of the refractory period, the myelin sheath,
and local neurons.
32. The sodium–potassium pump enables a neuron membrane to return to its resting potential shortly after an action
potential.
a. True
b. False
ANSWER: False
RATIONALE: The refractory period depends on two facts: The sodium channels are closed, and potassium
is flowing out of the cell.
DIFFICULTY: Medium
LEARNING OBJECTIVES: BIPS.KALA.24.01.15 - Describe the importance of the refractory period, the myelin sheath,
and local neurons.
33. When an action potential starts, it back-propagates into the cell body and its dendrites.
a. True
b. False
ANSWER: True
RATIONALE: An action potential starts in an axon and propagates without loss from start to finish.
However, at its start, it “backpropagates” into the cell body and dendrites (Lorincz and

a. True
b. False
ANSWER: True
RATIONALE: When an action potential back-propagates into a dendrite, the dendrite becomes more
susceptible to the structural changes responsible for learning.
DIFFICULTY: Medium

RATIONALE: To increase the speed still more, vertebrate axons evolved a special mechanism: sheaths of
myelin, an insulating material composed of fats and proteins.
DIFFICULTY: Medium
LEARNING OBJECTIVES: BIPS.KALA.24.01.15 - Describe the importance of the refractory period, the myelin sheath,
and local neurons.
36. Many local neurons do not have an axon.
a. True
b. False
ANSWER: True
RATIONALE: Many tiny neurons, called local neurons, have no axon and communicate only with their
immediate neighbors.
DIFFICULTY: Medium
LEARNING OBJECTIVES: BIPS.KALA.24.01.15 - Describe the importance of the refractory period, the myelin sheath,
and local neurons.
37. People typically use only 10 percent of their brain.
a. True
b. False
ANSWER: False
RATIONALE: You use all of your brain, regardless of how well you are using it.
