168. What are the two divisions of the nervous system?
ANSWER:
The two divisions of the nervous system are the anatomical division and the functional divisions.
The anatomical division is composed of the central nervous system (CNS) and the peripheral nervous system
(PNS). The central nervous system includes the cerebrum, cerebellum, brainstem, spinal cord, thalamus,
subthalamus, and basal ganglia. The peripheral nervous system includes the spinal nerves, cranial nerves,
and sensors.
The functional divisions of the nervous system are composed of the autonomic nervous system (ANS) and
the somatic nervous system. The autonomic nervous system (involuntary component) includes the
sympathetic nervous system and the parasympathetic nervous system. The somatic nervous system is the
voluntary component of the nervous system.

170. What is locked-in syndrome, what causes this disorder, and what impact does this syndrome have on the client?
ANSWER:
Locked-in syndrome is a devastating disorder that may develop following a brainstem stroke or
cerebrovascular accident (CVA). This disorder causes complete paralysis of all muscles with the exception of
the ocular muscles that control movement of the eyes. Usually locked-in syndrome does not impede sensory or
cognitive function. Thus the client is able to think normally, but cannot communicate his or her thoughts,
feelings, or needs. In order to communicate with others, the client usually must learn a system of eye blinks.
171. Which cranial nerve is considered to be the final and also the first cranial nerve, where is it located, and what purpose
might this nerve serve in humans?
ANSWER:
Cranial nerve 0, also called the terminal nerve, is considered by scientists to be the final and also the first
cranial nerve. This nerve is located on either side of the nasal septum. While cranial nerve 0 is definitely
present in sharks and mammals, there is a controversy among scientists as to whether this nerve exists
functionally in humans. Many investigators believe that cranial nerve 0 is present in almost one-half of
humans and that individuals may use this nerve as a subconscious means for selecting their mates.
172. What are the four lobes of the brain that control cognitive and sensory functions?
ANSWER:
The four lobes of the brain that control cognitive and sensory functions are the (1) frontal lobe, which is
essential for cognitive function, contains the speech center, and predominates in planning, as well as the
initiation and inhibition of voluntary motion; (2) parietal lobe, which is responsible for receiving somatic
(body) sense; (3) temporal lobe, which is a vitally important site for auditory and language reception and
processing; and (4) occipital lobe, which is the region that receives visual stimulation and also processes
higher level visual data.
173. The loss of which two areas of sensory function are of particular concern to speech-language pathologists and
auditory specialists?
ANSWER:
Speech-language pathologists and auditory specialists are particularly interested in the areas of sensory
function that are connected with hearing and vestibular function. When there is a failure of sensory systems,
the nervous system loses the valuable information that it needs to function properly. A loss of hearing during
the prenatal period of life can retard the development of speech and language. Severe problems with
communication may arise when hearing loss occurs following the prenatal period. Vestibular dysfunction can
cause vertigo and serious problems with balance. Meniere's disease (endolymphatic hydrops) is an example of
a disorder associated with vestibular dysfunction.
