where is the gracile fasciculus located
The fibers that enter the spinal cord below the sixth thoracic segment form the gracile fasciculus (gracile tract), and fibers that enter the cord above the sixth thoracic segment are located laterally and form the cuneate fasciculus (cuneate tract). The gracile fasciculus (historically termed the tract of Goll) is present throughout the length of the spinal cord; it contains afferents from the lower trunk and extremities below the T6 spinal cord segment.
