Tracts Flashcards
(12 cards)
Dorsal Column - Medial Lemniscus Pathway conveys what information?
Mnemonic: PVT 2
Sensations of Vibration, proprioception, 2-point discrimination, and light touch from skin and joints.
Dorsal Column - Medial Lemniscus Pathway decussates where?
Medulla
“Feeling Very Patient” unlike the Spinothalamic tract which is “Not Very Patient”.
What are tests for the Dorsal Column - Medial Lemniscus Pathway?
JPS
Romberg’s
Vibration
Soft touch
Lateral Spinothalamic Tract decussates where?
At the spinal level
Remember that the Lateral Spinothalamic Tract carries Nociception and Temperature. So a way to remember that it decussates straight away is to think they are “Not That Patient.”
Lateral Spinothalamic Tract conveys what information?
Nociception
Temperature
How do you test Lateral Spinothalamic Tract?
Sharp/dull
Hot/cold
Anterior Spinothalamic Tract conveys what information?
Crude touch
How do you test Anterior Spinothalamic Tract ?
Soft touch - cotton ball
Anterior Spinothalamic Tract decussates where?
Spinal level
Dorsal and Ventral Spinocerebellar Tracts decussate where?
They do not
Dorsal and Ventral Spinocerebellar Tracts conveys what information?
Unconscious proprioception
How do you test for Dorsal and Ventral Spinocerebellar Tracts?
Cerebellar tests
