The back strings, a string on hay. and one on the left. side, is that part, the sector of the white matter of the spinal cord which, posteriorly, lies between the entry of the hind roots of hay. and we. side and which forward and to the sides are bounded by the hind horns of the spinal cord. Each hind cord contains important ascending conduction pathways that convey high-resolution (detailed) information about mechanical stimuli from the skin and musculoskeletal system (bones, joints and muscles); so-called backstring qualities.
Calculated from the spinal cord segment T6 upwards, the posterior cord can be divided into an inner part: fasciculus gracilis and an outer part: fasciculus cuneatus. Below the spinal cord segment T6, the posterior cord consists solely of fasciculus gracilis.
