Localization of the lumbar pools of motoneurones which provide hindlimb muscles in the rabbit.
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.
