After his motorcycle accident 1 year ago, Jim's personality and behavior have changed significantly. He
now has severe short-term memory problems and is disorganized, foul-mouthed, and impulsive. Jim can
neither foresee the consequences of his actions nor does he possess insight into his behaviors. Damage
of which cerebral lobe would largely be responsible for these problems? ANS -frontal

hormonal imbal ances, and is unable to assume a normal sleep-wake cycle. Which neurological structure
is primarily thought to be responsible for these functions? ANS -hypothalamus
After a gunshot wound to the head, Jose has been in a vegetative state. Although he shows no response
to verbal commands, his cough and gag reflex, swallowing reflex, and pupillary response all remain
intact. Which neurological structure is responsible for these reflexive functions? ANS -brainstem
From the time Francis was a young child, he displayed tics and uncontrollable movements (e.g. tongue
protrusion and neck snapping). Although these dyskinesias have improved somewhat as he has aged,
they still remain to a moderate extent as an adult. Which neurological structure is believed to be
responsible for this movement disorder? ANS -basal ganglia
Mr. Jones has been diagnosed with Parkinson disease and displays the festinating gait, intention
tremors, and masked face associated with this disease. Which neurological structure is believed to be
responsible for these symptoms and is often the target of drug and surgical treatment? ANS -basal
ganglia
Alice has been experiencing decreased proprioception; she has difficulty understanding the location of
her limbs in space and in relation to each other. She walks with great clumsiness or motor
incoordination and ataxia. Magnetic resonance imaging has most likely detected a tumor in which
neurological structure? ANS -cerebellum
,Josh, a 7 year old in elementary school, has difficulty interpreting others' emotions through their facial
expressions, verbal tone, and body language. He also has difficulty generating age-appropriate feelings
of empathy for his classmates. Josh has been given a diagnosis of autism spectrum disorder (ASD) by his
pediatrician. Researchers have targeted which one of the below neurological structures as dysfunctional
in ASD? ANS -amygdala
When Mrs. Anderson walked into the hospital to visit her newly born grandson, the scents and odors of
the hospital setting reminded her of the time when, 5 years ago, her husband was a hospital patient
after experiencing cardiac arrest. Which 2 structures are primarily responsible for long-term memory
storage of emotionally laden events associated with a distinct odor? ANS -hippocampus and olfactory
bulb/tract
After a stroke, Ms. Rodriguez displays aphasia, a language disorder in which she has difficulty speaking
and inter preting others' words. Language disorders such as aphasia commonly occur in which
hemisphere? ANS -left

b. normal pressure hydrocephalus; reduced absorption of CSF by the arachnoid villae
c. congenital hydrocephalus; reabsorption of CSF by the arachnoid villae
d. normal pressure hydrocephalus; foramina blockage ANS -congenital hydrocephalus; foramina
blockage, excessive production of CSF, choroid plexus tumors
Mr. Wilson has been diagnosed with normal pressure hydrocephalus. This form of hydrocephalus is
caused by _____ and can result in _____ .

Joshua has been admitted to the emergency room after a severe auto vehicle accident in which he was a
passenger. He is diagnosed with increased intracranial pressure and neural tissue compression resulting
from hemorrhage into the subdural space. Traumatic brain injuries often involve:
a. blockage of the foramen of Magendie, resulting in hydrocephalus
b. rupture of the middle meningeal artery, resulting in hemorrhage ANS -rupture of the middle
meningeal artery, resulting in hemorrhage
Mrs. Greenly has been diagnosed with Parkinson disease. Her physician explains to the family that, while
several pharmaceutical options are available, none are highly effective because such drugs cannot reach
the brain. The neurological structure by which potentially toxic molecules are prevented from reaching
the brain is called the:
a. dura mater
b. cerebral aqueduct
c. blood-brain barrier
d. arachnoid villae ANS -blood-brain barrier
