| syndrome, third and fourth pharyngeal pouch | See syndrome, digeorge. (12 Dec 1998) |
|---|---|
| douglas' pouch | A sac or recess formed by a fold of the peritoneum. (12 Dec 1998) |
| ileoanal pouch | A pouch constructed from the ileum and anastomosed to the proximal anus for restoration of normal continence after proctocolectomy. Kock pouch, a continent ileostomy with a reservoir and valved opening fashioned from doubled loops of ileum. Synonym: Kock ileostomy. (05 Mar 2000) |
| third and fourth pharyngeal pouch syndrome | <syndrome> Also called the digeorge syndrome (dgs), this disorder is characterised by (1) low blood calcium levels (hypocalcaemia) due to underdevelopment (hypoplasia) of the parathyroid glands which control calcium; (2) underdevelopment (hypoplasia) of the thymus, an organ behind the breastbone in which lymphocytes mature and multiply; and (3) defects of the heart involving the outflow tracts more than from the heart. most cases of dgs are due to a microdeletion in chromosome band 22q11.2. A small number of cases have defects in other chromosomes, notably 10p13. Named after the american paediatric endocrinologist angelo digeorge. Another name for dgs is hypoplasia of the thymus and parathyroids. (12 Dec 1998) |
| ultimobranchial pouch | A transient fifth pharyngeal pouch; it is now considered to be incorporated into the caudal pharyngeal complex, the cells of which become the parafollicular cells (C cells) of the thyroid. Uterovesical pouch, a pocket formed by the deflection of the peritoneum from the bladder to the uterus in the female. Synonym: excavatio vesicouterina, cavum vesicouterinum, vesicouterine pouch. (05 Mar 2000) |
| laryngeal pouch | A small diverticulum provided with mucous glands extending upward from the ventricle of the larynx between the vestibular fold and the lamina of the thyroid cartilage; it is a vestigial structure, being a much larger structure interdigitating with the neck musculature in some of the great apes where it serves as a resonating chamber. Synonym: sacculus laryngis, appendix ventriculi laryngis, Hilton's sac, laryngeal pouch. Origin: L. Sacculus (05 Mar 2000) |
| alveolar dead space | The difference between physiologic dead space and anatomical dead space; it represents that part of the physiologic dead space resulting from ventilation of relatively underperfused or nonperfused alveoli; it differs specifically in being placed so as to fill and empty in parallel with functional alveoli, rather than being interposed in the conducting tubes between functional alveoli and the external environment. (05 Mar 2000) |
| anatomical dead space | The volume of the conducting airways from the external environment (at the nose and mouth) down to the level at which inspired gas exchanges oxygen and carbon dioxide with pulmonary capillary blood; formerly presumed to extend down to the beginning of alveolar epithelium in the respiratory bronchioles, but more recent evidence indicates that effective gas exchange extends some distance up the thicker-walled conducting airways because of rapid longitudinal mixing. Compare: alveolar dead space, physiologic dead space. Synonym: anatomical airway. (05 Mar 2000) |
| antecubital space | The fossa in front of the elbow, bounded laterally and medially by the humeral origins of the extensors and flexors of the forearm, respectively, and superiorly by an imaginary line connecting the humeral condyles. Synonym: fossa cubitalis, antecubital space, chelidon, triangle of elbow. (05 Mar 2000) |
| anterior clear space | On lateral chest radiographs, the region dorsal to the sternum and ventral to the ascending aorta. Synonym: anterior clear space. (05 Mar 2000) |
| apical space | The space between the alveolar wall and the apex of the root of a tooth where an alveolar abscess usually has its origin. (05 Mar 2000) |
| axillary space | <anatomy> The underarm area. (16 Dec 1997) |
| Berger's space | The space between the patellar fossa of the vitreous and the lens. (05 Mar 2000) |
| Bogros' space | A triangular space between the peritoneum and the transversalis fascia, at the lower angle of which is the inguinal ligament; it contains the lower portion of the external iliac artery. Synonym: Bogros' space, spatium retroinguinale. (05 Mar 2000) |
| Bottcher's space | The blind pouch at the end of the endolymphatic duct. (12 Dec 1998) |
