ESOPHAGEAL HIATUS Meaning and Definition

  1. The esophageal hiatus refers to a specific anatomical structure located within the diaphragm, a muscular sheet separating the chest from the abdomen. It is a passageway through which the esophagus, a long muscular tube connecting the throat to the stomach, passes from the chest to the abdomen.

    More specifically, the esophageal hiatus can be defined as a hole or an opening in the diaphragm where the esophagus penetrates through. It is positioned at the level of the tenth thoracic vertebra, which is commonly referred to as T10.

    The esophageal hiatus is essential for the proper functioning of the digestive system as it enables the passage of food and liquids from the throat to the stomach. It also plays a crucial role in preventing the reflux of stomach acid back into the esophagus, a condition known as gastroesophageal reflux disease (GERD). The diaphragm muscles surrounding the esophageal hiatus contribute to the closure of the esophagus, preventing this reflux.

    In certain situations, the esophageal hiatus may become weakened or enlarged, resulting in a condition called hiatal hernia. This occurs when a section of the stomach protrudes upward into the chest through the hiatus. Hiatal hernias can cause symptoms such as heartburn, regurgitation, and difficulty swallowing.

    Overall, understanding the esophageal hiatus is important for appreciating the anatomy and functions of the diaphragm and the gastrointestinal system.

Etymology of ESOPHAGEAL HIATUS

The word "esophageal hiatus" is composed of two parts: "esophageal" and "hiatus".

1. "Esophageal" refers to the esophagus, which is the muscular tube that connects the throat (pharynx) to the stomach. The term "esophageal" is derived from the Greek word "oesophagos" (οισοφάγος), which is a combination of "oeso" (οὖσο) meaning "gullet" and "phagos" (φάγος) meaning "eat" or "swallow".

2. "Hiatus" refers to an opening or a gap. It comes from the Latin word "hiatus", which means "gap" or "break". The Latin term is derived from the verb "hiare", meaning "to gape" or "to open wide".
