Final answer:
The fasciculus gracilis carries sensory information from the lumbar and sacral vertebral levels. These levels correspond to the lower extremity and lower body regions.
Step-by-step explanation:
The fasciculus gracilis is a part of the dorsal column system in the spinal cord, which is responsible for conveying sensory information regarding touch and proprioception from the lower part of the body to the brain. Specifically, the fasciculus gracilis carries information from the lower extremity and the lower body, which corresponds to our lumbar and sacral vertebral levels. As the sensory axons travel up the spinal cord, they remain in the position they entered, which means that axons from lower vertebral levels (i.e., lumbar and sacral) position medially within the fasciculus gracilis, whereas those from higher vertebral levels (i.e., thoracic and cervical) are positioned laterally and form the fasciculus cuneatus.
