Front 4

To get to the spinothalamic tract, 2nd order neurons must cross the:

Back 4

Anterior comissure

Front 5

Both the medial and lateral spinothalamic tracts end in the

Back 5

Thalamus

Front 6

Name the 4 places that 2nd order neurons can terminate at

Back 6

Thalamus, reticular formation, nucleus raphe magnus, periaqueductal gray

Front 7

2nd order neurons link to 3rd order neurons here and lead to cerebral cortex

Back 7

Thalamus

Front 8

2nd order neurons go here and are responsible for the arousal of pain

Back 8

Reticular formation
