Question 9 of 10

9. If there was a spinal cord lesion at L1 in the anterolateral spinal cord, where would the symptoms manifest? Hint

Quiz Answer Key and Fun Facts

1. A fast adapting receptor is:

Answer: Pacinican Corpuscles

Pacinian corpuscles, Meisner's corpuscles and hair follicles are fast adapting receptors in the skin. Merkel's and Ruffini's adapt slowly.

2. The dorsal column in the spinal cord becomes the what in the medulla:

Answer: medial lemniscus

3. The medial lemniscus ascends and synapses in what structure in the brain?

Answer: VPL of the thalamus

The VPL is the third synapse in this pathway.

4. The dorsal column pathway carries what types of information to the spinal cord and brain?

Answer: 2-point discrimination

It also carries pressure sensations

5. What information does the anterolateral system pathway NOT carry?

Answer: sound

6. What is the slow pain pathway?

Answer: paleospinothalamic

This carries slow pain to the thalamus, which is basically the dull, aching non-localized pain.

7. What fibers carry pain?

Answer: a-delta and c-fibers

8. Which of the following is a misplaced nucleus in the brain?

Answer: mesencephalic nucleus of 5

It is a misplaced nucleus because it is a peripheral nervous system nucleus found in the central nervous system

9. If there was a spinal cord lesion at L1 in the anterolateral spinal cord, where would the symptoms manifest?

Answer: at L3 and below on the contralateral side

The ALS pathway crosses over to the opposite side of the spinal cord in the anterior white commissure 2 segments above where the specific axon enters

10. If you damaged your cerebellum, which symptoms might you experience?

Answer: dizziness or vertigo

The cerebellum controls balance and this is affected in injury.
