Ascending pathways Flashcards
Where is the primary sensory cortex?
Postcentral gyrus
Where does the dorsal column pathway decussate?
Medulla
Where does the dorsal column pathways first order neurone synapse?
Cuneate or gracile nucleus in medulla
What information does dorsal column pathway transmit?
Fine touch, pressure, vibration and proprioception
What information does anterolateral system transmit?
Crude touch, pain, temperature, pressure
What info does anterior spinothalamic tract transmit?
Crude touch, pressure
What info does lateral spinothalamic tract transmit?
Pain, temperature
Where does the anterolateral system decussate?
Spinal cord (tip of dorsal horn)
What does trigeminothalmic pathway transmit?
Fine touch, pressure, vibration and proprioception from the face
Where do sensory neurones from trigeminothalmic pathway enter the brainstem?
Enter pons through trigeminal ganglion
Where do the first order neurones of trigeminothalmic tract synapse?
Trigeminal nucelus
Where does the trigeminothalmic tract decussate?
Pons
What does the pain and temperature system transmit?
Pain and temperature from V
Where do sensory fibres from pain and temperature system of V enter the brainstem?
Pons through trigeminal ganglion
Where do first order neurones from pain and temperature system of V synapse?
Spinotrigeminal complex in medulla
