esophageal hiatus of the diaphragm
Hernia, hiatus: Protrusion of the stomach up into the opening normally occupied by the esophagus in the diaphragm, the great dome of muscle that separates the thoracic (chest) cavity from the abdomen.
The area where the esophagus passes through the diaphragm is known as the esophageal hiatus. This opening allows the esophagus to connect the throat to the stomach, facilitating the passage of food. The diaphragm muscles surrounding this hiatus help prevent acid reflux by contracting during swallowing. It is located at the level of the tenth thoracic vertebra (T10) in the spinal column.
Esophagus
The spermatic cord passes through the inguinal canal into the abdominal cavity through the inguinal ring, which is an opening in the abdominal wall.
A hiatal hernia is when abdominal contents, like the intestines, protrude through a small hole that is designed for the esophagus to pass through the diaphragm. The herniation referrs to the strangling of the intestines and the hiatus is the name of the opening,
The opening where the esophagus passes through the diaphragm is called the esophageal hiatus or esophageal opening in the diaphragm.
the pharynx
The condition in which a portion of the stomach bulges up through the diaphragm into the thoracic cavity is called a "hiatal hernia." This occurs when the opening in the diaphragm, where the esophagus passes through, becomes enlarged, allowing part of the stomach to protrude. Hiatal hernias can lead to symptoms such as heartburn and acid reflux.
asf
A gullet opening is the opening of the second part of a frogs mouth. This is where this second opening begins.
