Which ascending spinal cord pathway transmits discriminative touch, conscious proprioception, and vibratory sense to the brainstem?
Answer and explanation
Correct answer: C. Dorsal column-medial lemniscal pathway
The dorsal column-medial lemniscal system (fasciculus gracilis and fasciculus cuneatus) carries fine touch, vibration, and conscious proprioception ipsilaterally to the medulla, where second-order neurons decussate to form the medial lemniscus. Spinothalamic carries pain and temperature.
