This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: Nervous System, Subject name: Physiology
Vibration sense is carried by which pathway? 
Select and explain. 
A. Ventral spinothalamic, B. Lateral spinothalamic, C. Dorsal columns, D. Anterolateral pathway
C: Dorsal columns
Answer: C: Dorsal columns 
Explanation: (C) Dorsal columns > A pattern of rhythmic pressure stimuli is interpreted as vibration.> The impulses responsible for the vibrating sensation are carried in the dorsal columns.> Degeneration of this part of the spinal cord occurs in poorly controlled diabetes, pernicious anemia, some vitamin deficiencies and occasionally other conditions; elevation of the threshold for vibratory stimuli is an early symptom of this degeneration.> Vibratory sensation and proprioception are closely related; when one is depressed, so is the other.
