Ascending Spinal Tracts

Question 1

Fasciculus Gracilis

Answer 1

Conveys discriminative touch, proprioception, etc. from the ipsilateral LE and lower trunk

Question 2

Fasciculus Cuneatus

Answer 2

Conveys discriminative touch, proprioception, etc. from the ipsilateral UE and Upper Trunk; loss of unconscious proprioception from UEs

Question 3

Lateral Spinothalamic

Answer 3

Conveys pain and temperature info from the contralateral side of the body 2 segments below the level and distally

Question 4

Ventral Spinothalamic

Answer 4

Conveys pain and temperature info both sides of the body

Question 5

Ventral Spinocerebellar

Answer 5

conveys unconscious proprioception bilaterally from the whole limbs, modulates motor activity via descending pathways

Question 6

Spinoreticulothalamic

Answer 6

Bilaterally conveys poorly localized pain, arousal to stimuli

Question 7

Dorsal Spinocerebellar

Answer 7

Conveys ipsilateral unconscious proprioception form individual muscles to the cerebellum

Question 8

Propriospinal

Answer 8

Provides local circuitry to modulate reflexes
