摘要：

The location of the motoneurons that innervate the main tongue protrusor muscle, genioglossus, was studied in the 1-2 day old, 10-14 day old and adult rat. Following injection of the retrograde axonal tracer WGA-HRP into the genioglossus muscle, labeled neurons were localized to a discrete column within the ventral division of the hypoglossal nucleus in both the neonatal and adult rats. These results demonstrate an adult pattern of genioglossus innervation in the neonatal rat.
