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.
采用辣根过氧化物酶逆行运输技术，研究了支配18块选定猕猴前肢肌肉的脊髓运动柱的组织情况。在猫的后肢对该方法的可靠性进行了评估。支配对手有相似作用的前臂肌肉的运动柱在前角似乎有重叠。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。
