Capable of forming receptor sites to specific antigens based upon a individuals genetic make-up. This is often used to explain that some individuals cannot develop an allergy to something-or-other because they are not genetically predisposed (capable).

Group of nerve cell bodies found in the peripheral nervous system.

The removal of gas or fluid from the stomach (also called venting).

Stomach and intestine.

A disorder in which there is recurrent return of stomach contents back up into the esophagus, frequently causing heartburn, a symptom of irritation of the esophagus by stomach acid. This can lead to scarring and stricture of the esophagus, which can require stretching (dilating).

Death and decay of body tissue, often occurring in a limb, caused by insufficient blood supply and usually following injury, disease or infection.

The two chains of sympathetic ganglia extending along the ventrolateral surfaces of the vertebral column from the upper cervical region to the coccyx. Each trunk consists of a series of sympathetic ganglia connected by a nerve cord. These nerve cords are composed largely of nerve fibers associated with the cell bodies within the ganglia. The right and left sympathetic trunks join, at the ventral surface of the coccyx, to form a single ganglion known as the ganglion impar, or ganglion of Walther. SEE sympathetic trunks.
