QUESTIONS & ANSWERS(RATED
A+)
Which of these does not directly describe the autonomic nervous system? -
ANSWERComposed of sensory neurons
What best describes the Broca's area? - ANSWERBroca's area is a premotor area
for speech sounds.
What is NOT part of the diencephalon? - ANSWERmedulla oblongata
What portion of the brainstem blends with the spinal cord after passing through the
foramen magnum? - ANSWERmedulla oblongata
A patient is unresponsive to sensory stimuli and a brain scan of the cerebrum shows
no cortical activity. During surgery to relieve pressure on her brain, the neurologist
notices damage to part of her diencephalon, explaining her symptoms. What part is
damaged? - ANSWERThe thalamus
Chronic alcohol abuse will not only cause an individual to develop liver damage but
may also lead to cerebellar damage. Damage to the cerebellum will cause the
individual to: - ANSWERappear clumsy and uncoordinated.
A patient enters the ER with loss of muscle function on the right side of her body.
The initial exam indicates she may have suffered a stroke in her: - ANSWERleft
cerebral hemisphere.
What is not part of the cerebrum? - ANSWERBrainstem
The cerebellum functions in __________. - ANSWERthe planning and coordination
of movement
The neurons responsible for hearing, language, memory, and emotions can be found
in the __________ lobe. - ANSWERtemporal
Which statement best describes the circadian rhythm? - ANSWERIn a 24-hour
period of time, we spend a period of time awake and a period of time asleep.
Damage to the cortex of the left cerebral hemisphere can result in inability to
__________. - ANSWERunderstand language and speak
The removal of both the left and right hippocampus will ultimately result in: -
ANSWERthe inability to form declarative memories.
, Your doctor is discussing the side effects of an upcoming surgery to remove your left
and right amygdala. He says that the effects can vary, but you should expect: -
ANSWERemotional abnormalities
In what dura mater fold is the superior sagittal sinus located? - ANSWERfalx cerebri
The meninges are protective membranes that surround the brain. CSF is a liquid
found within the meninges that help to protect and cushion the brain, increasing its
buoyancy. If a tear occurs in the meninges, CSF will begin to leak, leading to: -
ANSWERincreased pressure on the brain
An injury to the spinal cord is not possible below the: - ANSWERsecond lumbar
vertebra.
Visual stimuli that arrive in the thalamus are relayed to the: - ANSWERprimary visual
cortex in the occipital lobe.
How do painkillers relieve pain? - ANSWERBy blocking the transmission and
perception of the pain stimuli in the brainstem
At what point in the brain do upper motor neurons of the corticospinal tracts
decussate? - ANSWERmedullary pyramids
What role does dopamine play in motor control? - ANSWERDopamine binds
receptors on the caudate nucleus and putamen, inhibiting the globus pallidus. The
upper motor neurons are eventually activated.
The basal nuclei are a collection of cell bodies that modify the activity of upper motor
neurons to produce voluntary movements. Damage to any factor of this system
results in a movement disorder. Damage to any of the following will cause difficulty in
initiating movement except the: - ANSWERGlobus pallidus
The two brain structures concerned directly with maintenance of homeostasis
include certain nuclei in the brainstem and the _____. - ANSWERhypothalamus
Nearly all stimuli destined for the cerebral cortex must first pass through the
________. - ANSWERthalamus
The most important part of the brain in terms of our immediate survival is the: -
ANSWERbrainstem.
Integrative functions are carried out by the: - ANSWERcentral nervous system
Which of the following structures connects the brain to the spinal cord? -
ANSWERBrainstem
It is in the medulla oblongata that corticospinal tracts ______, meaning that the
motor fibers originating from the right cerebral cortex descend through the left side of
the spinal cord, and vice versa. - ANSWERdecussate
