viserosenory pathways

Question 1

tell me about the pathway od sympathatetic viscerosensory

Answer 1

receptor from the internal organs of the thoracolumbar region < peripheral sensory neurons in the DRG < terminate in ipsilateral side of spinal cord and from lamina 1 goes contralateral to spinothalamic tract T1 TO L3 < and then terminates in VPM of thalamus < and then, in the end, terminates in posterior insula cortex

Question 2

which tract gives the collateral branch while ascending and y?

Answer 2

sympathetic viscerosensory pathways give it while ascending it gives branch in medulla oblongata for hemostatic control regions

Question 3

pathway of parasympathetic sacral

Answer 3

receptor from the internal organs of the sacral region < peripheral sensory neurons in the DRG < terminate in ipsilateral spinal cord grey matter through the lamina 1 it goes contralateral to spinothalamic tract S2 TO S4 < and then terminates in VPL of thalamus < and then, in the end, terminates in posterior insula cortex

Question 4

where does taste sensation goes?

Answer 4

gustatory cortex in anterior insula and frontal operculum

Question 5

in the cranial parasympathetic tract the sensation ascends through ?

Answer 5

trigeminothalamic tract

Question 6

where is solitary nucleus complex present?

Answer 6

suoerior part of medulla oblongata

Question 7

where does Cranial parasympathetic terminates ?

Answer 7

Question 8

Which nuclei are involved in emotion in response to pain?

Answer 8

Question 9

what are the 3 major termination in spinoreticular tract

Answer 9
