What are the 2 sensory pathways and the 1 motor pathway? (+ where do they decussate)
Sensory
1. Dorsal column: fine touch, proprioception & vibration
decussates at medulla
2. Spinothalamic: (anterior - pressure, crude touch) + (lateral - pain, temp)
Decussates at level of entry
Motor
1. Corticospinal: voluntary movement
Decussates at medulla
Mx for encephalopathy
Rifaximin or lactulose
( to regulate BO)
