Role of glossopharyngeal nerve on the control of pigeon cervical esophagus motility.
The effects of i) glossopharyngeal section on the occurrence of the primary peristalsis and ii) electrical efferent stimulation of glossopharyngeal nerve on the EMG activity were studied in the pigeon cervical esophagus. The results pointed out that glossopharyngeal nerve is an indispensable requirement for the primary peristalsis occurrence and that motor sequence is centrally programmed.
