| duodenojejunal junction | Point along the course of the gastrointestinal tract where the duodenum ends and the jejunum begins; occurs approximately at the level of the L2 vertebra, 2-3 cm to the left of the midline; usually takes the form of an acute angle, the duodenojejunal flexure, and is supported by the attachment of the suspensory muscle (ligament) of the duodenum. (05 Mar 2000) |

| duodenojejunal angle | An abrupt bend in the small intestine at the junction of the duodenum and jejunum. Synonym: flexura duodenojejunalis, duodenojejunal angle. (05 Mar 2000) |
|---|---|
| duodenojejunal flexure | An abrupt bend in the small intestine at the junction of the duodenum and jejunum. Synonym: flexura duodenojejunalis, duodenojejunal angle. (05 Mar 2000) |
| duodenojejunal fold | A fold of peritoneum bounding the superior duodenal recess. Synonym: plica duodenalis superior, plica duodenojejunalis, duodenojejunal fold. (05 Mar 2000) |
| duodenojejunal fossa | A peritoneal recess extending upward behind the superior duodenal fold. Synonym: recessus duodenalis superior, duodenojejunal fossa, duodenojejunal recess, Jonnesco's fossa, superior duodenal fossa. (05 Mar 2000) |
| duodenojejunal hernia | A hernia in the subperitoneal tissues. Synonym: retroperitoneal hernia, Treitz's hernia. (05 Mar 2000) |
| duodenojejunal recess | A peritoneal recess extending upward behind the superior duodenal fold. Synonym: recessus duodenalis superior, duodenojejunal fossa, duodenojejunal recess, Jonnesco's fossa, superior duodenal fossa. (05 Mar 2000) |
| duodenojejunal sphincter | The sphincter supposedly present at the duodenojejunal flexure. (05 Mar 2000) |
| adhering junction | <cell biology> A type of junction between cells forming tissues that are subjected to stretching and pulling, such as the skin. This type of junction provides very tight contact between adjacent cells and allows the cells to fuction as a unit. Belt desmosomes are attachment sites that circle the cell, and spot desmosomes are small points of attachment across the cells surface. (15 Jan 1998) |
| amelodental junction | Amelodentinal junction, rarely used terms for dentinoenamel junction. (05 Mar 2000) |
| amnioembryonic junction | The line of amniotic attachment to the periphery of the embryonic disk. (05 Mar 2000) |
| anorectal junction | Transition from rectum to anal canal; corresponds to the perineal flexure, or the level at which the gut perforates the pelvic diaphragm; here the rectal ampulla narrows abruptly into a narrow slip. (05 Mar 2000) |
| anterior junction line | Radiographic projection of the mediastinal tissue septum between the upper lobes behind the sternum. (05 Mar 2000) |
| A-V junction | Imprecisely defined zone surrounding and including the A-V node and the adjacent atrial and ventricular myocardium. (05 Mar 2000) |
| cardioesophageal junction | The abrupt transition from oesophageal mucosa to that of the cardiac portion of stomach, demarcated internally in the living by the z-line, and approximated externally by the cardiac notch. (05 Mar 2000) |
| gap junction | <cell biology> A junction between two cells consisting of many pores that allow the passage of molecules up to about 900D. Each pore is formed by an hexagonal array (connexon) of six transmembrane proteins (connexins) in each plasma membrane: when mated together the pores open, allowing communication and the interchange of metabolites between cells. Electrical synapses are gap junctions and metabolic cooperation depends upon the formation of gap junctions. (18 Nov 1997) |
