brown squared syndrome

Question 1

what is brown squared syndrome?

Answer 1

anatomical disruption of nerve fibre tracts in one half of the spinal cord.

Question 2

what are clinical features of brown sequard syndrome?

Answer 2

Ipsilateral hemiplegia
Ipsilateral loss of proprioception and vibration
Contralateral loss of pain and temperature sensation

Question 3

what are the lateral corticospinal tracts responsible for?

Answer 3

motor movement- they are descending tracts

Question 4

where do corticospinal tracts deccusate?

Answer 4

the medulla of the brain stem- injury results in ipsilateral loss

Question 5

what are the main sensory tracts?

Answer 5

the dorsal column- responsible for fine touch and proprioception
and
the anterior and lateral spinothalamic tract responsible for pain and temperature sensation

Question 6

where do the dorsal columns decussate?

Answer 6

• the medulla of the brain- so injury results in ipsilateral loss

Question 7

where do the spinothalamic tracts decussate?

Answer 7

at the level of the spine- leading to contralateral loss of pain and temperature sensation if injured
