1. For the spinothalamic tract, which of the following statements is FALSE?
The first order neuron is ipsilateral
The first order neuron decussates
The third order neuron is contralateral
The cell body for the 3rd order neuron is located in the thalamus
This tract carries carries pain and temperature sensation
Since I misspoke in lecture concerning this info. You will get 2 points for answering either 1 or 2. But know that the correct answer is 2.

2. Where is his injury? Para or quadriplegic?
C7 – para
C5 – quad
T12 – quad
C 3 – para
L1 – para
Not sure
Go back to previous slide
Reflexes in legs?? Discuss spastic vs flaccid again
Upper or lower motor neuron lesion??

3. Why is the guy in blue “smarter”?
His brain is bigger
He has more brain weight for his body weight
He uses all of his brain
He just thinks he’s smarter
He has more cerebral cortex
Everyone will get credit for this question.

4. Damage to the left ventral horn at spinal cord levels C6 will cause:
Flaccid paralysis in right arm
Spastic paralysis in right arm
Flaccid paralysis in left arm
Spastic paralysis in left arm
Two of the above
I’m going to throw this question out. Know however, that the correct answer is 3. Yes, right after spinal cord damage, the person will have spastic paralysis due to spinal shock and on the exam, I will specify a time line. When ventral horn cells are damaged, it’s only the LMN’s that are damaged which leads to flaccid paralysis just like when you cut a peripheral nerve.

5. Can bacterial meningitis cause brain damage, coma and death?

7. Under normal conditions, what is in the dural sinuses?

“dirty” CSF
None of the above

8. Damage to the left precentral gyrus results in:

Motor problems on the right side of the body
Motor problems on both left and right
Sensory problems on the right side of the body
