Question

question 13 (2 points)
listen
which of the following is a characteristic of upper motor neuron lesions?
flaccid paralysis
decreased muscle tone
increased deep tendon reflexes
fasciculations
question 14 (2 points)
listen
where do the first - order neurons of the spinothalamic tract have their cell bodies?
spinal cord gray matter
thalamus
dorsal root ganglia
cerebral cortex

Explanation:

For Question 13, upper motor neuron lesions are characterized by increased deep - tendon reflexes. Flaccid paralysis, decreased muscle tone, and fasciculations are more associated with lower motor neuron lesions.
For Question 14, the cell bodies of the first - order neurons of the spinothalamic tract are located in the dorsal root ganglia. The spinal cord gray matter contains second - order neurons, the thalamus contains third - order neurons, and the cerebral cortex is the final destination for sensory information processing.

Answer:

Question 13: C. Increased deep tendon reflexes
Question 14: C. Dorsal root ganglia
