What are the neural pathways involved in saliva regulation during vomiting?

During vomiting, the regulation of saliva is primarily controlled by a complex interplay of neural pathways. The process of vomiting is initiated by the brainstem's vomiting center, which receives signals from various parts of the body, including the inner ear, gastrointestinal tract, and chemoreceptor trigger zone. Once activated, the vomiting center sends signals to multiple brain regions, such as the salivary nuclei, which regulates saliva production. These signals cause an increase in parasympathetic activity, leading to enhanced salivary gland secretion. Additionally, the vomiting center may also activate the sympathetic nervous system, resulting in decreased salivary gland activity. The intricate coordination of these neural pathways ensures the appropriate regulation of saliva during vomiting.
