1. The term neurotransmitter refers to __________
a) a chemical found in the synaptic vesicles that is released into the synapse.
b) any one of a number of chemical compounds that increase the activity of the endocrine system.
c) the chemical substance found in the cell membrane.
d) the DNA contained in the nucleus of every neuron.
2. An auto accident rendered Chris’s nervous system unable to send messages for him to breathe, so he is on a respirator. Which brain structure was damaged in the accident?
a) pons
b) medulla
c) cerebellum
d) reticular formation
3. This midbrain structure plays a central role in the development of Parkinson’s disease.
a) the reticular formation
b) the substantia nigra
c) the thalamus
d) the hypothalamus
4. As she walks out of the living room, Gloriann turns out the light. In this example, Gloriann’s __________ is active.
a) sympathetic nervous system
b) parasympathetic nervous system
c) autonomic nervous system
d) somatic nervous system
5. The thick band of neurons that connects the right and left cerebral hemispheres is called the ___________
a) cortex.
b) cerebrum.
c) corpus callosum.
d) cerebellum.
6. Karla flipped her mountain bike off the edge of a steep trail and fractured the right side of her skull. She now suffers from unilateral neglect, a condition defined by __________
a) a lack of emotional recognition or response.
b) an inability to detect objects in the visual periphery.
c) an inability to detect objects in the right visual field.
d) an inability to detect objects in the left visual field.
7. Difficulty producing the sounds required for speech due to damage in the frontal lobe is termed __________
a) Broca’s aphasia.
b) Broca’s apraxia.
c) Wernicke’s aphasia.
d) Wernicke’s apraxia.
8. Which of the following is NOT registered in the somatosensory cortex?
a) sound
b) pressure
c) temperature
d) pain
9. Many older adults have difficulty with being steady on their feet, having difficulty with their gait, and overall balance issues. Research suggests that this is because as we age we commonly experience a loss of __________
white matter.
gray matter.
substantia nigra cells.
cerebellar lobes.
10. Alisa is directed by her neurologist to have a test that will measure the magnetic fields created by the electricity of the neurons in her brain. Which of the following tests will Alisa be most likely to have?
MRI
SQUID
fMRI
PET scan
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)
