parasympathetic efferent information from the brainstem to the GI tract that stimulates
gastrointestinal activity
- the cephalic reflexes of digestion, such that the sight and smell of food stimulate GI
activity
The first hormone identified and named ... - Answers - - is produced by cells lining the
duodenum in response to acid coming from the stomach
