Burdach Tract

BURDACH TRACT, is located in the posterior columns of the spinal cord, where it occupies a position between the medial Goll's tract and the lateral root zone; anteriorly lies the main posterior column tract. The B. tract originates from the cells of the intervertebral ganglia, fibers as part of the posterior root penetrate into the posterior column through Lissauer's zone, where they divide into ascending and descending branches; the ascending branches form the B. tract; as they ascend, the fibers increasingly deviate medially and transition into Goll's tract (see Goll's tract), being replaced by fibers from upper roots. Upon transition

into the medulla oblongata, the B. tract changes its name to funiculus cuneatus and gradually terminates in the nucleus of this tract - nucleus funic. cuneati. By function, the B. tract is a conductor of deep and (partially) tactile sensitivity for the upper extremity and upper parts of the trunk. Being centripetal, the Burdach tract degenerates in the ascending direction when the posterior roots or intervertebral ganglia are affected.
