🥵 HARD
We are starting to focus on tracts, and clinical presentations of their lesions. This can take a few attempts at revision to get right – so don’t be discouraged. Neurophobia is real, but not permanent! Best of luck!

Clinical Neuroanatomy: Part Three
Question 1 |
Stem 1 of 4
A patient has notable MR spine results as follows:T1 MR shows hypodensity region corresponding to syrinx of the central canal at the C5 level only.
What is the inferior-most level of changes to thermoception given this rare, isolated site?
C4 | |
C5 | |
C6 | |
C7 | |
C8 |
Question 2 |
Stem 2 of 4
On which side would you expect theroception to be most attenuated?Left side neck | |
Right side thorax | |
Right side ncek | |
Right sided upper limb | |
None of the above |
Question 3 |
Stem 3 of 4
Study the relevant image below. Given the somatotopic organisation, which coloured pin represents the area of T5 nociceptive fibre afferent flow?
Blue | |
Red | |
Yellow | |
Green | |
None of the above |
Question 4 |
Stem 4 of 4
In regards to the previous schematic, what is the function of the tract marked by the pink pin?Conscious vibrational sense | |
Fine touch | |
Crude touch | |
Pain transmission | |
Unconscious proprioception |
Question 5 |
Ipsilateral stretch receptor information | |
Contralateral stretch receptor information | |
Ipsilateral tendon tension information | |
Contralateral tendon tension information | |
All of the above |
Question 6 |
Ventral spinocerebellar tract | |
Dorsal spinocerebellar tract | |
Anterior spinothalamic tract | |
Dorsal column medial lemniscus system | |
Trigeminothalamic tract |
Question 7 |
One | |
Two | |
Three | |
Four | |
Five |
Question 8 |
A group of interneurons in the middle lamina of the spinal cord grey matter | |
Part of the crude touch transmission pathway | |
The decussation point of the dorsal column | |
The tract through which pain fibres ascend 1/2 levels on entry into the spinal cord before decussation | |
None of the above |
Question 9 |
It does not decussate and remains ipsilateral | |
Once | |
Twice | |
Three times | |
None of the above |
Question 10 |

Which of the following vignettes are most appropriate to describe a classic presentation?
Ipsilateral dorsal column and spinothalamic loss | |
Contralateral loss of crude touch, ipsilateral loss of vibration | |
Contralateral loss of conscious proprioception, contralateral loss of pain | |
Contralateral loss of vibration, ipsilateral loss of pain | |
None of the above |
