NUR612 Exam 7 questions and answers
CNS - Correct answer -brain and spinal cord, protected by the skull and vertebral column; "control
center"
PNS - Correct answer -outside structures of the CNS; input-output system for relaying information to
the CNS and transmits output that controls effector organs; "robot- does what control center tells it to do"
Afferent neurons - Correct answer -sensory; located in the lateral columns
Efferent neurons - Correct answer -motor; located in the ventral columns
Myelomeningocele - Correct answer -contents of spinal cord protruding through the skin
Anencephaly - Correct answer -lack of skull closure and brain protruding through the skin
32 or more pairs of spinal nerves - Correct answer -8 cervical, 12 thoracic, 5 lumbar, 5 sacral, and 2 or
more coccygeal (look at page 371 in book)
CN 1 - Correct answer -olfactory (smell)
CN 2 - Correct answer -optic (part of brain, optic & retina)
CN 3 - Correct answer -oculomotor (pupillary constriction)
CN 4 - Correct answer -trochlear (moves eyes down and in)
, CN 5 - Correct answer -trigeminal (facial expression, blink, sneeze, mastication, speech, tense soft
palate, protects ears from loud noise)
CN 6 - Correct answer -abducens (lateral eye deviation)
CN 7 - Correct answer -facial (gag reflex, taste, salivation, facial expression)
CN 8 - Correct answer -auditory/ vestibulocochlear (sense of head position, hearing)
CN 9 - Correct answer -glossopharyngeal (kinesthesia, taste, salivary reflex: mucous secret, assist
swallow)
CN 10 - Correct answer -vagus (parasympathetic efferent, emesis, swallow)
CN 11 - Correct answer -spinal accessory (head, shoulder movement)
CN 12 - Correct answer -hypoglossal (tongue movement, reflexes)
thalamus - Correct answer -relays motor and sensory signals to cerebral cortex; regulates
consciousness, sleep, and altertness
thalamus damage effects - Correct answer -sensory perception issues, motor problems, thalamic pain
syndrome (intense pain from minimal stimuli), cognitive impairments such as memory and attention
issues
cerebrum - Correct answer -higher brain functions such as thought and action; divided into 2
hemispheres with various lobes responsible for different functions
cerebrum damage effects - Correct answer -varies depending on affected lobe
