- Biolaterally labeled motoneurons of uvala muscle were also found in the rostral section of the nucleus ambiguus.
- Labeled motoneurons of levator veli palatini and palatopharyngeus muscle were ipsilaterally located in the rostral part of the nucleus ambiguus.
- Nucleus ambiguus (NA) is an important visceral and somatic motor nucleus which establishes widely connections with the central nervous system and peripheral organs.
- Situs inersus totalis occurs in 50% of PCD patients (Kartagener's syndrome in PCD), and there are a few reports of PCD with heterotaxy (situs ambiguus), such as cardioascular anomalies.
- Labeled motoneurons of palatoglossus muscle were ipsilaterally located in both the rostral half of the nucleus ambiguus and the ventrolateral subdivision of the caudal half of the hypoglossal nucleus.
- Progress in the study on the nucleus ambiguus
