This is an important piece of the puzzle for me. I would like to know a little mor e about it.
When you say the intestines do not have nerve endings, does that mean no sensation in the intestines is possible? When I get gas/cramps of the usual indigestion kind, where does that pain originate? I had imagined it was an irritation/bloating/stretching of the large intestine, but by your claim the pain must originate elsewhere. Can you shed some light?
And just to be sure: the peritoneum is the inner lining of the abdomen, correct? Behind your abdominal muscles?
