What Is Cancer Of The Esophagus? The esophagus is a muscular tube that connects the throat to the stomach and carries food into the stomach. The esophagus is usually between 10 to 13 inches long. The normal adult esophagus is roughly 3/4 inch across at its smallest point. The wall of the esophagus has several layers. Cancers of the esophagus start from its inner layer and grow outward. The innermost layer of the esophagus is called the mucosa. The mucosa has two parts. The epithelium forms the lining of the esophagus and is made up of flat, thin cells called squamous cells. The lamina propria is a thin layer of connective tissue right under the epithelium. There is a thin layer of muscle tissue under the mucosa that is called the muscularis mucosae. The next layer is the submucosa. Some parts of the esophagus have mucus-secreting glands in this layer. The layer under the submucosa is a thick band of muscle called the muscularis propria. This layer of muscle contracts in a coordinated, rhythmic way to force food along the esophagus from the throat to the stomach. The outermost layer of the esophagus is formed by connective tissue. It is called the adventitia. The upper part of the esophagus has a special area of muscle at its beginning that relaxes to open the esophagus when it senses food or liquid coming toward it. This muscle is called the upper esophageal sphincter. The lower part of the esophagus connects to the stomach. This connection is called the gastroesophageal junction or GE junction. There is a special area of muscle near the GE junction called the lower esophageal sphincter. The lower esophageal sphincter controls the movement of food from the esophagus into the stomach and it keeps the stomachâ s acid and digestive enzymes out of the esophagus. The stomach has strong acid and enzymes that digest food. The epithelium or lining of the stomach is made of glandular cells that release acid, enzymes, and mucus. These cells have special features that protect them from the stomachâ s acid and digestive enzymes. ...
