采用辣根过氧化物酶逆行转运技术研究了支配18条猕猴前肢肌肉的脊髓运动柱的组织结构。以猫后肢为实验对象，对该方法的可靠性进行了评价。支配前臂肌肉的运动柱与手的类似动作似乎在前角重叠。伸肌运动神经元通常位于屈肌运动神经元的腹侧和/或外侧。控制手部运动的运动神经元主要位于C8和T1节段。
The organization of spinal cord motor columns innervating 18 selected macaque forelimb muscles was studied with the technique of retrograde transport of horseradish peroxidase. The reliability of the method was evaluated in the cat hindlimb. Motor columns innervating forearm muscles with similar actions on the hand appear to overlap in the anterior horn. Extensor motoneurons are generally positioned ventral and/or lateral to flexor motoneurons. Motoneurons controlling hand movement are located primarily in segments C8 and T1.
