The close approximation of labeled terminal arborization and labeled cells signifies direct intersegmental feedback circuit.
标记细胞旁有标记终支说明脊髓节段间有着反馈联系。
In lumbar injection cases a prominent plexus of labeled terminal arborization could be seen in the ventrolateral part of the C_5 ventral horn. Corresponding plexus was not found in the lumbar cord in cervical injection cases.
L注射例在C5腹角的腹外侧可见到明显的丛状终支,而于C注射例在L5则未见到此特殊结构。
Labeled cells were consistently found in region ⅹ which was also the area of dense labeling of terminal arborization, suggesting that this region plays a remarkable role in intersegmental connection.
Ⅹ区标记细胞恒定,标记终支也较密集,提示该区在脊髓节段间的联系方面起着一定的作用。
