The Rexed laminae comprise a system of ten layers of grey matter (I-X), identified in the early 1950s by Bror Rexed to label portions of the grey columns of the spinal cord. Similar to Brodmann areas, they are defined by their cellular structure rather than by their location, but the location still remains reasonably consistent. ==Laminae== * Posterior/dorsal horn: I-VI * * Lamina I: marginal nucleus of spinal cord or posteromarginal nucleus * * Lamina II: substantia gelatinosa of Rolando * * Laminae III and IV: nucleus proprius * * Lamina V: Neck of the dorsal horn * * Lamina VI: Base of the dorsal horn, * Intermediate zone: VII and X * * Lamina VII: intermediomedial nucleus, intermediolateral nucleus, nucleus dorsalis of Clarke in the thoracic and upper lumbar region〔Blumenfeld, Hal (2010). Neuroanatomy through Clinical Cases. Sunderland, MA: Sinauer Associates.〕 * * Lamina X: central gray matter i.e. neurons bordering Central canal; Grisea Centralis〔 * Anterior/ventral horn: VIII-IX * * Lamina VIII: motor interneurons; Commissural nucleus〔 * * Lamina IX: lateral (in limb regions) and medial motor neurons, also phrenic and spinal accessory nuclei at cervical levels, and Onuf's nucleus in the sacral region * Centrally * * Lamina X: Central Zone, grey matter surrounding the central canal 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「rexed laminae」の詳細全文を読む スポンサード リンク
