The exact localisation of the motor pools of anterior horn providing the different nerves of the brachial plexus remains unclear. The data obtained have been furnished by different methods: Nissl methods furnish cytoarchitectonic data -- Golgi methods furnish dendro-architectonic data. The topographical data were obtained by the chromatolytic modifications of the moto-neurons after a peripheral nerve injury. The recently used method of the retrograde transport of HRP permits to get information about the exact localisation and the dendritic extent of the neurons of a motor pool related to a particular nerve. We have studied the localisation of the nerves of the brachial plexus in the cervical enlargement of the spinal cord. We have determined the exact extent of the different motor pools in relation to each nerve. It seems that two different regions may be recognized in the anterior horn: a ventro lateral one in relation with the girdle muscles and a dorso lateral region related with the more distal muscles of the anterior limb.
为臂丛神经不同分支提供神经支配的前角运动神经元池的确切定位尚不清楚。已获取的数据来自不同方法：尼氏染色法提供细胞构筑数据，高尔基染色法提供树突构筑数据。地形学数据是通过周围神经损伤后运动神经元的染色质溶解变化获得的。最近使用的辣根过氧化物酶逆行运输方法能够获取与特定神经相关的运动神经元池的确切定位及其树突范围的信息。我们研究了臂丛神经在脊髓颈膨大处的定位。我们确定了与每条神经相关的不同运动神经元池的确切范围。在前角似乎可以识别出两个不同区域：一个腹外侧区域与带肌相关，一个背外侧区域与前肢更远端的肌肉相关。
