Abdominal functional electrical stimulation (abdominal FES) is the application of a train of electrical pulses to the abdominal muscles, causing them to contract. The abdomen is comprised primarily of the digestive tract and other accessory organs which assist in digestion, the urinary system, spleen, and the abdominal muscles (shown below). stomach that part of the vertebrate gut system which follows the oesophagus, is expanded to form a chamber, and whose walls secrete pepsinogen giving rise to PEPSIN, RENNIN (in young mammals) and hydrochloric acid from the OCYNTIC CELLS.
