TRANSPYLORIC PLANE Meaning and
Definition
-
The transpyloric plane is a term used in anatomy to describe an imaginary horizontal plane that passes through a specific anatomical landmark known as the "pylorus."
The pylorus is the narrowest part of the stomach, located at the junction between the stomach and the small intestine, known as the duodenum. It serves as a muscular valve that controls the release of partially digested food from the stomach into the small intestine for further digestion and absorption.
The transpyloric plane is strategically positioned in relation to the pylorus. It is defined as a horizontal line that intersects the body exactly halfway between the anterior superior iliac spine (ASIS) and the pubic symphysis in humans. In other words, it is an imaginary line at the level of the L1 vertebra or the first lumbar vertebra.
The transpyloric plane is an essential reference point in clinical practice, especially in surgery and radiology. It helps healthcare professionals locate and describe specific anatomical structures or assess the position of organs during physical examinations, radiographic imaging, or surgical procedures. For example, it is commonly used to guide the placement of nasogastric tubes, which are inserted through the nose, down the throat, and into the stomach for various diagnostic or therapeutic purposes. Overall, understanding the transpyloric plane aids in precise anatomical identification and facilitates communication among healthcare professionals.

Etymology of TRANSPYLORIC PLANE
The word "transpyloric" is derived from two root components: "trans-" and "pyloric".
1. "Trans-" is a prefix that originates from Latin, meaning "across" or "beyond". It is commonly used in medical terminology to describe something that goes or extends across or beyond a particular location or structure.
2. "Pyloric" refers to the pylorus, which is a narrowed opening between the stomach and the small intestine. It is derived from the Greek word "pylōros" (πύλωρος), consisting of "pylē" (πύλη) meaning "gate" or "door" and "oros" (ὅρος) meaning "guardian" or "warder".
