17. Which one of the following statement is wrong?
(A)The spinal cord and brainstem nuclei are home to second-order neurons, the first step of centralnervous system (CNS) processing.
(B) A proto-oncogene, c-fos, is activated after potentially tissue-damaging stimuli are applied tomost tissues.
(C) A systematic comparison study of Fos and pERK as markers of spinal nociceptive activationrevealed greater specificity for activity in nociceptive pathways (vs. non-nociceptive activation)using Fos.
(D) The spinal cord is segregated into areas that, on gross examination, appear as white and greymatter and consist of predominantly myelinated nerve fiber tracts and cell bodies, respectively.
(E) Using Rexed’s cytoarchitecture-based classification system, there are at least 10 differentlayers or laminae of neurons—of which the first six (I to VI) are termed the dorsal horn of the spinalcord .
