CCEB - NERO PATHWAYS EXAM QUESTIONS AND
ANSWERS
What type of neuron detects pain? ANSWER: nociceptor
Which neuron crosses the midline in sensory pathways? ANSWER 2nd
Where does acute pain travel? - STT connects the substantia gelitinosa with the
thalamus and cortex.
Where does persistent pain end? - ANSWER Spinoreticular tract connects the
hypothalamus and limbic system.
What does STT transmit? ANSWER Pain
Temp
Light touch.
Where are the first-order neurons of the spinothalamic tract located? - Answer:
DRG
What does the dorsal white column transmit? ANSWER Pressure.
Vibration
Two-point discriminatory touch.
proprioception
Where is the first-order neuron in the DWC located? - ANSWER DRG
, Where is the first synapse in the DWC? ANSWER: Nucleus Gracilis/Cuneatus
Which decussation is lower? Answer: Pyramids or Medial Lemniscus.
The job of descending pain pathways - ANSWER modulate and inhibits pain
transmission.
Where does the descending pain pathway begin - ANSWER Periaqueductal gray
matter
What hormone can suppress pain sensation? ANSWER: Enkephalins
Dorsal spinocerebellar tract - ANSWER The inferior peduncle communicates
temperature, proprioception, and touch sensations from the lower body and legs to
the inferior cerebellum.
ANSWER for ventral spinocerebellar tract Pain sensation and proprioception are
transmitted from the legs and lower trunk to the ipsilateral cerebellum.
decussates at the level of entrance, followed by the superior peduncle.
ANSWER: Olfactory receptor cells receive substances that are interpreted as odors.
Primary olfactory neurons are unmyelinated bipolar neurons.
