  • Title: [Experimental study of motor nerve innervation of uvala muscle].
    Author: Zhong W, Wang H, Zhang K.
    Journal: Zhonghua Kou Qiang Yi Xue Za Zhi; 2001 May; 36(3):197-8. PubMed ID: 11812341.
    Abstract:
    OBJECTIVE: To investigate the motor nerve innervation of uvala muscle. METHODS: Horseridish peroxidase (HRP) retrograde tracing technique was used in conjunction with selective intracranial severing of cranial nerve rootlets in 8 rabbies. RESULTS: Following HRP injection into uvala muscles, labeled motoneurons were located in the rostral section of nucleus ambiguus. No labeled motoneurons were found in the facial nucleus. Labled motoneurons were ipslaterally abolished after the cranial rootlets of accessory nerve on one side were intracranially severed. CONCLUSIONS: Uvala muscles are innervated by the motoneurons in the nucleus ambiguus. The axons of those motoneurons come out of the cranium through the cranial rootlet of the accessory nerve, then join the vagus, distributed via the pharyngeal branches of vagus.
