The localization of the pools of motoneurones (Mns) to the main hindlimb muscles was performed in the rabbit, using the retrograde transport of HRP from motor end plates. After 48 h survival time, the large alpha Mns were labeled. All the pools were met inside L6-S2 limits and a functional organization was observed: the pools to proximal muscles formed a ventral group of Mns and the pools to distal muscles a dorsal group, with flexor and extensor pools apart. The relative disposition of the different pools fits with that described in the cat and rat.
利用辣根过氧化物酶（HRP）从运动终板逆行运输的方法，在兔身上对支配主要后肢肌肉的运动神经元池进行定位。存活48小时后，大型α运动神经元被标记。所有运动神经元池均在L6 - S2范围内找到，并观察到一种功能组织：支配近端肌肉的运动神经元池形成一个腹侧运动神经元组，而支配远端肌肉的运动神经元池形成一个背侧运动神经元组，屈肌和伸肌运动神经元池分开。不同运动神经元池的相对位置与猫和大鼠中描述的相符。
