Excessive stimulation of vagus nerve in humans may lead to:

Options

  1. Ahoarse voice
  2. Bpeptic ulcers
  3. Cefficient digestion of proteins
  4. Dirregular contractions of diaphragm.

Correct answer

B. peptic ulcers

Step-by-step solution

Excessive stimulation of vagus nerve in humans may lead to peptic ulcer. Vagal stimulation increases peristalsis which in excess, secretes more HCl and pepsin from stomach. These causes erosion through protective barrier of mucus and muscularis mucosa into the submucosa which leads to peptic ulcer.
