- Inputs Related to the Airway Reflexes to the Larynx
抄録
The glottis closes during not only cough reflex but also sneezing. It indicates that the activity of laryngeal motor neurons within the nucleus ambiguus is influenced by both the superior laryngeal and the trigeminal afferents. In this study, the convergence of inputs originated from the superior laryngeal and the anterior ethmoidal nerves is examined in decerebrate cats. Thirty two neurons are activated orthodromically by ipsilateral stimulation to the superior laryngeal nerve. Fifty eight neurons are activated orthodromically by ipsilateral stimulation to the anterior ethmoidal nerve. These two neuronal groups are overlapped each other in the nucleus reticularis parvicellularis of medulla. However, the neurons receiving afferents from the superior laryngeal nerve tend to exist in the dorso-lateral portion of the nucleus, while the neurons receiving afferents from the ethmoidal nerve tend to exist in the medio-ventral portion. Seven neurons receive afferents from both nerves. Most of these neurons are located in the overlapped area of two neuronal groups, which is apart from the nucleus ambiguus. The projectional pattern that different inputs converge into the reticular neurons outside of the nucleus ambiguus can be useful for evoking the adequate airway reflex related to the larynx.
