Visceral pain is pain that results from the activation of nociceptors of the thoracic, pelvic, or abdominal viscera (organs). Visceral structures are highly sensitive to distension (stretch), ischemia and inflammation , but relatively insensitive to other stimuli that normally evoke pain such as cutting or burning.

In the abdomen, general visceral afferent fibers usually accompany sympathetic efferent fibers. This means that a signal traveling in an afferent fiber will begin at sensory receptors in the afferent fiber's target organ, travel up to the ganglion where the sympathetic efferent fiber synapses, continue back along a splanchnic nerve from the ganglion into the sympathetic trunk, move into a ...
Abdominal pain can be referred to as visceral pain or peritoneal pain. The contents of the abdomen can be divided into the foregut , midgut , and hindgut . [ 14 ] The foregut contains the pharynx , lower respiratory tract , portions of the esophagus , stomach , portions of the duodenum (proximal), liver , biliary tract (including the ...
Referred pain, also called reflective pain, [1] is pain perceived at a location other than the site of the painful stimulus.An example is the case of angina pectoris brought on by a myocardial infarction (heart attack), where pain is often felt in the left side of neck, left shoulder, and back rather than in the thorax (chest), the site of the injury.
Visceral and viscus (from Latin viscera 'internal organs'): associated with organs within the body's cavities and pertaining to the innermost layer. [57] For example, the stomach is covered with a lining called the visceral peritoneum, as opposed to the parietal peritoneum. Viscus can also be used to mean "organ". [57]
Visceral hypersensitivity In FGID there is poor association of pain with GI motility in many functional GI disorders. These patient often have a lower pain threshold with balloon distension of the bowel (visceral hyperalgesia ), or they have increased sensitivity even to normal intestinal function; Visceral hypersensitivity may be amplified in ...
Visceral fascia (also called subserous fascia) suspends the organs within their cavities and wraps them in layers of connective tissue membranes. Each of the organs is covered in a double layer of fascia; these layers are separated by a thin serous membrane. The outermost wall of the organ is known as the parietal layer
