Taxonomic definition A posterior propriospinal fasciculus of spinal cord is a proper tract of origin in spinal cord [tractus proprius originis medullae spinalis ] which contains ascending sensory fibers from the posterior horn [cornu posterius ] as well as descending fibers.
Notes
Nathan and Smith described the Propriospinal fasciculi as Posterior or Dorsal, Lateral, and Anterior or Ventral Ground bundles (Nathan PW, Smith MC 1959 Fasciculi proprii of the spinal cord in man. Brain 82:610-668). The term Fasciculus septomarginalis (Septomarginal fasciculus) is used for: 1) the Oval bundle of Flechsig, present at lumbar levels; and 2) the Triangle of Philippe-Gombault, present at sacral levels (see Schoenen J, Grant G 2004 The spinal cord: Connections. In: Paxinos G, Mai JK, eds: The Human Nervous System, 2nd ed. Elsevier, Amsterdam, pp 236-265). The term Fasciculus interfascicularis is also known as the Comma tract of Schultze, present at cervical and high thoracic levels. According to Nathan and Smith (1959), the Comma tract consists of descending divisions of the cervical and upper thoracic dorsal roots. The Fasciculus cornucommissuralis is present throughout the cord, best developed at lumbar levels; situated along the medial side of the posterior grey column abutting the posterior commissure. It consists of ipsilaterally running propriospinal fibres (see Schoenen and Grant 2004).
