The nurse is teaching a class on the perception of pain. What will the nurse teach as being the second step in processing pain stimuli?
A) Thalamus
B) Reticular system
C) Limbic system
D) Cerebral cortex
Answer: D
The thalamus is the main relay station for sensory information. Pain information is then transmitted to the cerebral cortex as well as the reticular and limbic systems for the processing and interpretation of pain. The cerebral cortex is the second step in processing pain stimuli. The transmission of pain moves through the limbic system after the thalamus. Transmission of pain impulses occurs in the reticular system after traveling though the thalamus as the main relay station.
