duodenal etymology

Etymology:

  • Latin: duodenum
  • Greek: δωδεκάδακτυλος (dōdekadáktylos), meaning "twelve fingers"

Meaning:

The duodenum is the first part of the small intestine, extending from the stomach to the jejunum. It is approximately 12 finger-widths long (about 25-30 cm) in adults, hence its name "twelve fingers."

Origin:

The term "duodenum" was coined by the ancient Greek physician Herophilus of Alexandria (c. 335-280 BC). He observed that the length of the duodenum is approximately equivalent to the length of twelve human fingers placed side-by-side.

The name "duodenum" has been used continuously since the time of Herophilus, and it is still the standard anatomical term for the first portion of the small intestine in both English and other languages.
