Question

practice it
which nervous system is responsible for stimulating the cephalic phase of digestion?
parasympathetic nervous system
sympathetic nervous system
central nervous system
enteric nervous system
autonomic nervous system

Explanation:

The cephalic phase of digestion is the initial stage where the body prepares for food intake. The parasympathetic nervous system plays a crucial role in stimulating digestive processes such as salivation, gastric acid secretion, and enzyme release. The sympathetic nervous system is more associated with the "fight - or - flight" response and inhibits digestion. The central nervous system is the brain and spinal cord, which are involved in the cephalic phase but not the direct stimulator. The enteric nervous system controls the gastrointestinal tract but is not the main stimulator for the cephalic phase. The autonomic nervous system includes both sympathetic and parasympathetic, but the specific one for this phase is parasympathetic.

Answer:

Parasympathetic nervous system.
