Review | Graded A+
1. If a patient experiences sudden weakness on one side of the body and
difficulty speaking, which type of stroke should be suspected, and what
immediate action should be taken?
A hemorrhagic stroke should be suspected, and the patient should be
given aspirin.
No action is needed as these symptoms are not serious.
An ischemic stroke should be suspected, and immediate medical
attention should be sought.
A TIA should be suspected, and the patient should rest.
2. The largest part of the human brain is the:
Diencephalon
Tentorium
Cerebellum
Cerebrum
3. These contain the ganglia for the parasympathetic nervous system that target
the intrinsic eye muscles to change the diameter of the pupil
superiomesenteric ganglion
sympathetic trunk ganglia
intramural ganglia
ciliary ganglion
pterygopalatine ganglion
,4. Jim Bob cannot direct his gaze upward to see the brim of his hat. Which of Jim
Bob's cranial nerves may be injured?
Oculomotor and Trochlear
Oculomotor only
Abducens and Trochlear
Oculomotor and Abducens
Trochlear only
5. What is the primary role of the brain ventricles?
To store neurotransmitters.
To produce and circulate cerebrospinal fluid.
To regulate blood flow in the brain.
To transmit electrical signals between neurons.
6. When you encounter a bear while hiking, which part of your nervous system
triggers an increase in your heart rate and breathing to help you run away?
the central nervous system
the parasympathetic nervous system
somatic nervous system
cranial nerves
the sympathetic nervous system
7. Which of the following is true concerning the cerebellum ?
Cerebellum plans body movements
The anterior lobe receives info from the body trunk
, Internal gray matter and external white matter
The vermis coordinates the trunk and shoulders
8. All of the following are functions of the hypothalamus except:
Filters out unimportant sensory information
Regulates water balance
Regulates sleep
Links the nervous and endocrine systems
9. Which spinal nerves are included in the lumbar plexus?
L01-L04
L04-S04
L01-S01
C01-C05
10. Describe the role of the cerebellum in maintaining gait and balance,
particularly in the context of a stroke.
The cerebellum regulates emotions and decision-making processes.
The cerebellum coordinates voluntary movements and helps
maintain balance, which is crucial for steady gait.
The cerebellum is responsible for producing speech and language.
The cerebellum processes visual information for spatial awareness.
11. What are the two primary outcomes of a spinal cord injury?
Loss of consciousness and paralysis
, Decreased strength and increased sensation
Paralysis and decreased sensation
Increased strength and sensation
12. Which portion of the brain is the largest?
pons
cerebrum
medulla oblongata
hypothalamus
cerebellum
13. Which nerve is responsible for sensation in the posterior thigh?
Common fibular nerve
Saphenous
Sciatic
Femoral
14. Describe the role of the ciliary ganglion in the regulation of pupil size.
The ciliary ganglion mediates parasympathetic signals that control
the intrinsic eye muscles, leading to pupil constriction.
The ciliary ganglion is involved in sympathetic responses affecting
heart rate.
The ciliary ganglion is responsible for sensory input from the eye.
The ciliary ganglion regulates blood flow to the digestive system.
