ACH

if it's about salivation then it is controlled by parasym and sympth both but mainly by parasym in which case the neurotransmitter is ACh which I think is acting through phospholipase C .... may be I am totally wrong .... waiting for the answer

Correct Answer Correct answer is F

Stimulation of acid secretion within stomach is separated into three phases: Cephalic, Gastric, and Intestinal.

Cephalic phase - mediated by Cholinergic and Vagal mechanisms, which are triggered by Thought, smell, sight, and taste of food.


Gastric phase - mediated by presence of gastrin, which is triggered by chemical stimulus of food and distension of stomach.


Intestinal phase - initiated when protein - containing food enters the duodenum. Influences down regulating gastric secretion after a meal.



This child's cephalic phase was acting up and it is mediated by Acetylcholine. Remember, in GIT, Vagus nerve and Cholinergic has acetylcholine.
