Answer: d. chronic stress could cause sympathetic activation, resulting in peptic ulcers.
Explanation: Parasympathetic activities in the Gastrointestinal tract include gastrointestinal secretions which aid the digestion of food while sympathetic activities inhibits these secretions.
The sympathetic nervous system is activated during the flight or fight response that we display in such situations as when we are stressed. When this happens, the sympathetic system prevents duodenal gland activity which makes the duodenal lining unprepared for the arrival of chyme, a mixture of partially digested food and digestive secretions. This could result in sores in the intestinal tract or peptic ulcers.
Answer:
D
Explanation:
Peptic Ulcer is due to damage to the mucosa lining of the stomach, and the small intestine. if the mucosa lining of the first part of the intestine is damaged the type of ulcer is called Duodenal Ulcer.It is usually characterised with upper abdominal pain, vomiting , weight loss, belching etc.It common causes are due to the effects Bacterial Helicobacter pylori and non-steroid noninflammatory drugs on the mucosa lining of the first part of the intestine.
Evidence had shown that chronic stress induced sympathetic activation, by causing disruption in the pathways of Hypothalamic-Pituitary- Adrenal-Axis(HPA), which may trigger peptic ulcer due to reduction in blood flow to the damaged(from eroding effects of pepsin and gastric acid) mucosa lining, resulting in peptic ulcer.
