Final answer:
The fundus is the dome-shaped region lateral and superior to the esophageal connection with the stomach, located above and to the left of the cardia and beneath the diaphragm.
Step-by-step explanation:
The dome-shaped region lateral & superior to the esophageal connection with the stomach is known as the fundus. The stomach is divided into four distinct regions: the cardia (or cardiac region), which is where the esophagus connects to the stomach, the fundus, the body, and the pylorus. The fundus is located above and to the left of the cardia, and inferior to the diaphragm. The body of the stomach is below the fundus and is the main part of the stomach. The pylorus is the funnel-shaped end of the stomach that connects to the duodenum.
