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.
Chronic visceral pain from vascular mechanisms is caused by changes in the arterial or venous blood vessels that supply blood to the viscera of the thoracic, abdominal, and pelvic cavities and the head or neck region. It can also be caused by a disorder of the vascular system that causes pain in other areas of the body.
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 ...
It is an area that is insensitive to pain due to its association with the lung and innervation by visceral sensory neurons. [8] Visceral pleura also forms interlobular septa (that separates secondary pulmonary lobules). [9] Interlobular septa contains connective tissue, pulmonary veins, and lymphatics. [10]
If a chest pain patient suspects that he is suffering a myocardial infarction, he can calm down, remain in a position that is comfortable, calling emergency medical services and trying any other action of the applicable first aid process. Chest pain is a common symptom encountered by emergency medical services.
The transpyloric plane, also known as Addison's plane, is an imaginary horizontal plane, located halfway between the suprasternal notch of the manubrium and the upper border of the symphysis pubis at the level of the first lumbar vertebrae, L1.
Costochondritis, also known as chest wall pain syndrome or costosternal syndrome, is a benign inflammation of the upper costochondral (rib to cartilage) and sternocostal (cartilage to sternum) joints. 90% of patients are affected in multiple ribs on a single side, typically at the 2nd to 5th ribs.
