Chapter 2 - Quick Quiz 2
Answer Key
1.
a
Explanation: Neurotransmitters are chemicals. (Page 41, Factual, LO 2.3)
2.
b
Explanation: The medulla is responsible for breathing. (Page 46, Factual, LO 2.6)
3.
b
Explanation: The loss of dopamine-producing neurons in the substantial
nigra may explain the loss of physical control associated with Parkinson’s disease. (Page
47, Factual, LO 2.7)
4.
d
Explanation: Turning out the light requires voluntary muscle movement. (Page 49,
Factual, LO 2.9)
5.
c
Explanation: The corpus callosum connects the right and left cerebral hemispheres. (Page
51, Applied, LO 2.10)
6.
d
Explanation: Unilateral neglect refers to difficulty paying attention to or
remaining aware of objects in the left visual field after right hemispheric damage. (Page
53, Conceptual, LO 2.11)
7.
a
Explanation: Damage to the frontal lobe can involve Broca’s area, which can
lead to expressive aphasia. (Page 57, Factual, LO 2.12)
8.
a
Explanation: Sound impulses are processed in the temporal lobes. The somatosensory
cortex is in the parietal lobes. (Page 58, Factual, LO 2.13)
9.
b
Explanation: Some studies have found that gray matter loss with aging is a common
neurological event. (Page 61, Factual, LO 2.16)
10. b
Explanation: The SQUID, or superconducting quantum interference device, is
used to show the magnetic changes produced by the electricity in our neurons. (Page 64,
Factual, LO 2.20)
