Abstract

The topographical distribution of motoneurons innervating the digastric muscle in the rabbit and guinea pig was re-examined by the retrograde tracing method of HRP (horseradish peroxidase). Motoneurons innervating the anterior belly of the digastric muscle of the rabbit and guinea pig constituted a longitudinal cell column in the ventromedial part of the motor nucleus of the trigeminal nerve. Motoneurons innervating the posterior belly of the digastric muscle were localized in the accessory facial nucleus. No motoneurons supplying the digastric muscle were found within the main facial nucleus.

摘要

采用辣根过氧化物酶（HRP）逆行追踪法，对家兔和豚鼠支配二腹肌的运动神经元的局部定位分布进行了重新研究。支配家兔和豚鼠二腹肌前腹的运动神经元，在三叉神经运动核腹内侧部构成一个纵向细胞柱。支配二腹肌后腹的运动神经元位于面神经副核内。在面神经主核内未发现支配二腹肌的运动神经元。
