What sensory modalities are from Spinothalamic tract?
pain and temperature
What sensory modalities come through Dorsal Column?
soft touch, proprioception, two-point discrimination
what is brown sequard syndrome?
Incomplete spinal cord lesion characterised by:
- ipsilateral upper motor neuron paralysis
- and (ipsilateral) loss of proprioception,
- contralateral loss of pain and temperature sensation.
can be more stuff depending on location and severity
Are Spinothalamic and dorsal column ascending or descending pathways?
Ascending- sensory
Is the descending pathways motor or sensory?
MOTORRRR
Does the descending motor pathway decuss?
Yes. Pyramids.
If there is a lesion below pyramids the effect on motor function would be on which side of the body?
Ipsilateral? (I think)
If there’s a lesion above pyramids, the motor function would be affected on which side of the body (in relation to lesion)?
contralateral (I think?… lemmie know if I’m wrong!!)
What are the two main descending tracts?
- corticospinal tract
- autonomic pathways (esp bladder, bowel, sexual function)
