-
Lateral spinothalamic damage Area 1,2,3
- Left entire body
- Specific/ less specific pain and temp
-
Lateral spinothalamic tract starts at
S5
-
Lateral spinothalamic tract where 1st order meets 2nd
Laminae I-IV
-
What can you perceive on a thalamic level
specific and less specific touch, Pressure, pain, temp, vibration and auditory input
-
BML nuclei
- receives incoming info and relay to area 1 2 and3
- intralaminar nuclei –perceive this info
-
Ventral/ Anterior spinothalamic tract modality
Less specific touch and pressure
-
Ventral/ Anterior spinothalamic tract receptors
Free nerve endings and hair end organs
-
Ventral/ Anterior spinothalamic tract pathways
- Primary neuron: receptor --> DRG --> DH and synapses in laminae I-IV, substancia gelatinosa
- Secondary: crosses to contralateral side in the ventral white commissure --> lateral portion ventral funiculus --> forms bundle and ascends as lateral spinothalamic tract through lateral luminesces and synapses in thalamus (VPL)
- Tertiary: ascends through internal capsule to post central gyrus of cerebral cortex (Areas 1,2,3 then 5 and 7) for interpretation
-
