During the pharyngeal phase of swallowing, where do impulses from receptors in the oropharynx travel?

1. Deglutition has a voluntary phase followed by the pharyngeal and esophageal phases. 2. The pharyngeal phase begins when receptors in the oropharynx are stimulated by the bolus. 3. Those impulses travel to the deglutition center, a collection of neurons in the medulla oblongata. 4. The center then sends impulses back that raise the uvula and soft palate to close off the nasopharynx. 5. The salivatory nuclei also sit in the brain stem rather than the cerebral cortex, so that option is wrong twice over. 6. The myenteric and submucosal plexuses are intrinsic gut plexuses and handle motility and secretion locally. _Source: OpenStax Anatomy and Physiology (CC BY 4.0), Ch 23 "The Digestive System", section 23.3 The Mouth, Pharynx, and Esophagus_
