1. Describe the functions of the cerebrum in relation to wakefulness and
cognitive processes.
The cerebrum is responsible for maintaining wakefulness and is
involved in higher cognitive functions such as thought, speech, and
behavior.
The thalamus relays sensory information but does not control
wakefulness.
The cerebellum coordinates movement and balance but does not
regulate wakefulness.
The brainstem controls basic life functions but is not involved in higher
cognitive processes.
2. What is the Brodmann area associated with the frontal eyelids?
Brodmann area 4
Brodmann area 6
Brodmann area 1
Brodmann area 8
3. If a patient has sustained an injury to the brainstem affecting the Reticular
Activating System, what symptoms might they exhibit?
Enhanced sensory perception
Altered levels of consciousness
Increased motor coordination
Improved memory recall
,4. Where is the Medulla Oblongata located in the brain?
In the cerebellum
In the temporal lobe
In the frontal lobe
At the base of the brain, above the spinal cord
5. In a clinical setting, how might understanding the affective-motivational
system aid in pain management strategies?
By focusing solely on the physical aspects of pain.
By ignoring the emotional responses to pain.
By tailoring interventions that address both emotional and sensory
components of pain.
By using only pharmacological treatments.
6. If a patient is experiencing chronic pain and is treated with a medication that
enhances Enkephalin activity, what physiological effect would you expect?
Increased sensitivity to pain
Reduced perception of pain
Decreased neurotransmitter release
Enhanced motor function
7. Cognitive operations in the brain cannot occur without the effective
functioning of:
Forebrain
Cingulate gyrus
, Peripheral nervous system
Reticular activating system
8. The ______ is the largest part of the diencephalon.
hypothalamus
thalamus
pituitary stalk
9. Describe the characteristics that differentiate acute pain from chronic pain.
Acute pain is caused by psychological factors, while chronic pain is
purely physical.
Acute pain is temporary and resolves quickly, whereas chronic pain is
permanent and unmanageable.
Acute pain is always more intense than chronic pain, which is usually
mild.
Acute pain is characterized by its short duration and direct
association with injury or illness, while chronic pain persists for
longer periods and may not have a clear cause.
10. Describe the significance of Brodmann area 8 in relation to eye movement.
Brodmann area 8 is responsible for sensory perception.
Brodmann area 8 regulates heart rate.
Brodmann area 8 is involved in the control of voluntary eye
movements and is significant for coordinating eye position.
Brodmann area 8 processes auditory information.
, 11. Describe the significance of the corpus callosum in facilitating
communication between brain hemispheres.
The corpus callosum allows for the transfer of information between
the left and right hemispheres, enabling coordinated brain function.
The corpus callosum regulates emotional responses.
The corpus callosum is involved in the formation of memories.
The corpus callosum is responsible for producing cerebrospinal fluid.
12. Approximately how much cardiac output does the brain receive?
7-12%
15-20 %
27-30%
22-25 %
13. How is pain tolerance best described?
Maximum amount of energy a nerve can generate
Maximum a person will allow
Average amount of discomfort a person reports
Minimum amount of pain a person can perceive
14. Which type of receptor do Enkephalins primarily interact with in the nervous
system?
Dopamine receptors
Serotonin receptors
GABA receptors
