19 Cerebral palsy may be caused by a temporary lack of oxygen during birth. True False

Correct Answer: True In difficult deliveries, a temporary lack of oxygen may lead to cerebral palsy.

17 Choose the true statement regarding second-order neurons. Second-order neuron cell bodies reside in a ganglion. Second-order neurons conduct impulses to the spinal cord or brain stem, where they synapse. Second-order neuron cell bodies reside in the thalamus. Second-order neuron cell bodies reside in the dorsal horn of the spinal cord.

Second-order neuron cell bodies reside in the dorsal horn of the spinal cord.

3 Choose the true statement regarding pyramidal cells. They are found within the cerebral sulci. They integrate sensory input to produce an understanding of an object being felt. They allow us to control our skeletal muscles. They provide control of our involuntary muscles.

They allow us to control our skeletal muscles.

5 Spatial discrimination is the ability to identify the specific region of the body being stimulated. True False

True

14 Which of the following meninges forms the loose, mid-layer brain covering? casa mater arachnoid mater pia mater dura mater

arachnoid mater

21 Which of the following are located in the lateral horns of the spinal cord gray matter? interneurons that receive input from visceral sensory neurons cell bodies of somatic motor neurons cell bodies of autonomic motor neurons interneurons that receive input from somatic sensory neurons

cell bodies of autonomic motor neurons The lateral horns consist mostly of the cell bodies of autonomic (sympathetic division) motor neurons that serve visceral organs.

11 Which of the following is NOT one of the major regions of the brain stem? midbrain pons medulla oblongata cerebellum

cerebellum

4 What is the main role of the olfactory cortex? detection of odors sight spatial discrimination sound interpretation

detection of odors

12 Which of the following regions acts as an autonomic reflex center of the brain? midbrain medulla oblongata cerebellum pons

medulla oblongata

13 People with __________ lapse abruptly into REM sleep from the awake state. narcolepsy epilepsy sleep apnea insomnia

narcolepsy

1. All of the structures of the CNS originate from the __________. cerebellum telencephalon hindbrain neural tube

neural tube

22 Transection (cross sectioning) of the spinal cord at T3 results in __________. quadriplegia paraplegia paresthesias spinal shock

paraplegia

18 Which of the following conditions results from viral destruction of ventral horn motor neurons? meningitis paraplegia amyotrophic lateral sclerosis poliomyelitis

poliomyelitis Poliomyelitis results from destruction of ventral horn motor neurons by the poliovirus. Early symptoms include fever, headache, muscle pain and weakness, and loss of some somatic reflexes. Later, paralysis develops and the muscles served atrophy.

2 Which of the following is NOT one of the three basic regions of a cerebral hemisphere? the basal nuclei the diencephalon the superficial cortex of gray matter the internal white matter

the diencephalon

15 Which of the following protects the brain from bloodborne metabolic wastes and most drugs? blood brain barrier cerebrospinal fluid dura mater pia mater

blood brain barrier

10 Which of the following regulates body temperature, food intake, and endocrine functions? hypothalamus pineal body epithalamus thalamus

hypothalamus

20 Anencephaly is a result of incomplete formation of the vertebral arches and can be caused by inadequate folic acid in the maternal diet. True False

False

16 Which of the following is a progressive degenerative disease of the brain that ultimately results in dementia? Alzheimer's disease Parkinson's disease mad cow disease Huntington's disease

Alzheimer's disease

6 Which of the following best describes the multimodal association cortex? It allows us to tie information that we receive to previous experience and knowledge and then helps us decide what action to take. It permits the perception of sound stimuli and stores them for future reference. It integrates sensory input to produce understanding of an object being felt. It regulates our heart and other involuntary muscles in response to environmental stimuli.

Correct Answer: It allows us to tie information that we receive to previous experience and knowledge and then helps us decide what action to take. The multimodal association cortex allows us to give meaning to the information that we receive, store it in memory if needed, tie it to previous experience and knowledge, and decide what action to take.

8 __________ is responsible for communication between cerebral areas and between the cerebral cortex and lower CNS centers. Broca's area The cerebral white matter The hypothalamus The thalamus

Correct Answer: The cerebral white matter The white matter deep to the cortical gray matter is responsible for communication between cerebral areas and between the cerebral cortex and lower CNS centers.

9 Which of the following is NOT a part of the diencephalon? epithalamus hypothalamus thalamus perithalamus

Correct Answer: perithalamus The diencephalon consists largely of three paired structures—the thalamus, hypothalamus, and epithalamus.

7 __________ is a division of labor in which each cerebral hemisphere has unique abilities NOT shared by its partner. Hemispherical association Cortical association Lateralization Hemispherication

Lateralization
