Spinal cord, posterior

the part, the sector, of the white matter of the spinal cord as posterior, a string on hay. and one on the left. side, located between the entry of the hind roots and the middle line. A back string primarily 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.
