The secretion of the exocrine pancreas is increased by the following except:

  • A. Vagal stimulation
  • B. Acetylcholine
  • C. Secretin
  • D. CCK
Correct Answer: A

Rationale: The correct answer is A: Vagal stimulation. Vagal stimulation does not directly increase the secretion of the exocrine pancreas. Acetylcholine, Secretin, and CCK are known to stimulate pancreatic secretion through various mechanisms. Acetylcholine acts through muscarinic receptors, Secretin is released in response to acidic chyme in the duodenum, and CCK is released in response to fat and proteins in the duodenum, all leading to increased pancreatic enzyme secretion. Vagal stimulation plays a role in the parasympathetic nervous system but does not directly stimulate pancreatic secretion.
