| tracheobronchial diverticulum | The endodermal lung primordium which will give rise to the epithelial lining of the respiratory tract. Synonym: lung bud. (05 Mar 2000) |
|---|
| superior tracheobronchial lymph nodes | Several large lymph nodes of the posterior mediastinal group located superior to the bronchi at their union with the trachea; receives lymph from inferior tracheobronchial lymph nodes and bronchopulmonary nodes; drain to paratracheal nodes. Synonym: nodi lymphatici tracheobronchiales superiores. (05 Mar 2000) |
|---|---|
| inferior tracheobronchial lymph nodes | Several large lymph nodes inferior to the tracheal bifurcation; they receive afferents from the bronchopulmonary nodes and the heart, and send efferents to the superior tracheobronchial and tracheal nodes. Synonym: nodi lymphatici tracheobronchiales inferiores, bifurcation lymph nodes, carinal lymph nodes. (05 Mar 2000) |
| tracheobronchial | <ornithology, zoology> Pertaining both to the tracheal and bronchial tubes, or to their junction; said of the syrinx of certain birds. Source: Websters Dictionary (01 Mar 1998) |
| tracheobronchial dyskinesia | Degeneration of elastic and connective tissue of bronchi and trachea. (05 Mar 2000) |
| tracheobronchial groove | The depression in the floor of the caudal end of the pharynx, continued downward on the ventral wall of the foregut; from it are developed the lower part of the larynx and the trachea, bronchi, and lungs. Synonym: tracheobronchial groove. (05 Mar 2000) |
| allantoenteric diverticulum | An endoderm-lined outpouching of the hindgut (in humans, the yolk sac of a very young embryo) representing the primordium of the allantois; in most amniotes, it grows into the extraembryonic celom; in humans, the distal part of the allantoic lumen is rudimentary, not extending beyond the body stalk. Synonym: allantoenteric diverticulum. (05 Mar 2000) |
| allantoic diverticulum | An endoderm-lined outpouching of the hindgut (in humans, the yolk sac of a very young embryo) representing the primordium of the allantois; in most amniotes, it grows into the extraembryonic celom; in humans, the distal part of the allantoic lumen is rudimentary, not extending beyond the body stalk. Synonym: allantoenteric diverticulum. (05 Mar 2000) |
| Rathke's diverticulum | A tubular outgrowth of ectoderm from the stomodeum of the embryo; it grows dorsad toward the infundibular process of the diencephalon, around which it forms a cup-like mass, giving rise to the pars distalis and pars juxtaneuralis of the hypophysis. Synonym: craniopharyngeal canal, hypophyseal pouch, Rathke's diverticulum, Rathke's pocket, Rathke's pouch. (05 Mar 2000) |
| ventricular diverticulum | A congenital outpouching of the right or left ventricle. (05 Mar 2000) |
| vesical diverticulum | A diverticulum of the bladder wall; may be either true or false type. (05 Mar 2000) |
| meckel diverticulum | <radiology> Rule of secondarys, 2 cm wide, 2 feet from I-C valve, males 2:1, 2% of population, antimesenteric (unlike duplication cyst), with or without ectopic gastric/pancreatic tissue see: Meckel scan (12 Dec 1998) |
| meckel's diverticulum | An out-pouching of the small bowel (ileum). Present in about 2% of people and usually occurs about 2 feet before the junction with the colon. Can be lined by stomach-type mucosa and ulcerate, perforate, or cause small bowel obstruction. (12 Dec 1998) |
| cervical diverticulum | A diverticulum in the neck derived from retention of part of one of the pharyngeal pouches (endodermal) or branchial grooves (ectodermal) of the embryo. (05 Mar 2000) |
| metanephric diverticulum | An outgrowth from the caudal portion of the mesonephric duct on either side, which grows cephalodorsally to make contact with the masses of metanephrogenous tissue (nephric blastemas) that give rise to the epithelial lining of the ureter and of the pelvis and the collecting ducts of the kidney.

| Pertik's diverticulum | An abnormally deep recessus pharyngeus. (05 Mar 2000) |
