GENERAL HISTOLOGY

Detailed explanation-1: -The esophagus is a collapsible muscular tube that serves as a passageway between the pharynx and stomach. As it descends, it is posterior to the trachea and anterior to the vertebral column. It passes through an opening in the diaphragm, called the esophageal hiatus, and then empties into the stomach.

Detailed explanation-2: -The esophagus passes through the diaphragm just before it meets the stomach, through an opening called the esophageal hiatus.

Detailed explanation-3: -In human anatomy, the esophageal hiatus is an opening in the diaphragm through which the esophagus and the vagus nerve pass.

Detailed explanation-4: -The esophageal hiatus is located in the muscular aspect of the diaphragm near the right crus. It is located at the level of T10. The posterior and anterior vagal nerves are also found passing through this hiatus.

Detailed explanation-5: -At the opening of your upper esophagus, there’s a ring-shaped muscle called the upper esophageal sphincter. Your upper esophageal sphincter senses when food or liquid is coming toward it. When it gets the signal, the sphincter relaxes or opens so that food can enter your esophagus.
