Definition of jejunum in English:

jejunum

nounPlural jejuna dʒɪˈdʒuːnəmdʒəˈdʒunəm

Anatomy

The part of the small intestine between the duodenum and ileum.
Example sentencesExamples
- The midgut eventually develops into distal duodenum, jejunum, ileum, caecum, appendix, ascending colon, and proximal two thirds of the transverse colon.
- The feathery-appearing bowel distal to the smoother contour duodenum is the jejunum, and it is in the right lower quadrant!
- Small bowel bleeding involving the jejunum and ileum is less common and more difficult to detect scintigraphically.
- The jejunum and ileum, with the exception of the Brunner's glands, are basically similar to the duodenum, although they tend to have more diffuse lymphoid cell aggregates or nodules in their submucosa than does the duodenum.
- Acute cholecystitis may cause the gall bladder to adhere to the adjacent jejunum or duodenum.

Derivatives

jejunal

adjective

Anatomy

Misplacement of the duodenal jejunal junction could be due to displacement from the multiple dilated small bowel loops or a malrotation.
Example sentencesExamples
- A meta-analysis of 45 studies between 1978 and 1989 with a total of 2,976 gastric tubes and 386 jejunal tubes found that aspiration rates were highly variable across different patient populations and studies.
- The patient had 2 notable congenital abnormalities: multiple dissecting pulmonary arterial aneurysms distributed in both lungs and multiple jejunal atresia with apple-peel deformity.
- The distal duodenum and duodenal jejunal junction is especially susceptible to damage because it is fixed in position.
- Ileal and jejunal duplication cysts that contain ectopic gastric mucosa are also rare causes of false positive studies.

Origin

Mid 16th century: from medieval Latin, neuter of jejunus 'fasting' (because it is usually found to be empty after death).
