, Question 1. A clinician is conducting an assessment of a male patient suspected of having a disorder of
motor function. Which of the following assessment findings would suggest a possible upper motor
neuron (UMN) lesion? (Points : 0.4)
The patient has decreased deep tendon reflexes.
The patient displays increased muscle tone.
The patient's muscles appear atrophied.
The patient displays weakness in the distal portions of his limbs.
Rationale: UMNs typically produce increased muscle tone, while hyporeflexia, muscle atrophy, and weakness in the
distal portion of the limbs are more commonly indicative of lower motor neuron (LMN) lesions
Question 2. A 51-year-old has been admitted to a rehabilitation center after hospital treatment for
an ischemic stroke. Which of the following aspects of the patient's history would not be considered to
have contributed to his stroke? (Points : 0.4)
He was diagnosed with type 2 diabetes eight years ago
Elevated cholesterol
Blood pressure that is normally 120/80
The patient is an African American Male
History of sickle cell anemia
Question 3. Following a spinal cord injury suffered in a motor vehicle accident, a 22-year-
old male has lost fine motor function of his finger and thumb, but is still able to perform gross
motor movements of his hand and arm. Which of the following components of his white matter
has most likely been damaged? (Points : 0.4)
The inner layer (archilayer)
The middle layer (paleolayer)
The outer layer (neolayer)
The reticular formation
Rationale: Fine manipulation skills are the domain of the outer layer, or neolayer, of tract systems. The inner and
middle layers and the reticular formation are not noted to be responsible for these functions.
Question 4. A 44-year-old female has been diagnosed with major depression. Which of
the following neuroimaging findings is most congruent with the woman's diagnosis? (Points
: 0.4)
Decreased brain activity in the pons and brain stem
Reduced activity and gray matter volume in the prefrontal cortex
Atrophy and decreased blood flow in the amygdala
Enlargement of the lateral and third ventricles and reduction in frontal and temporal volumes
Rationale: In some cases of familial major depressive disorder and bipolar disorder, PET and MRI studies have
