| vitelline | <biology> Of or pertaining to the yolk of eggs; as, the vitelline membrane, a smooth, transparent membrane surrounding the vitellus. Origin: L. Vitellus the yolk of an egg. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| vitelline artery | <anatomy, artery> An artery carrying blood to the yolk sac from the embryo. Synonym: arteria vitellina. (05 Mar 2000) |
| vitelline cord | A persistent yolk stalk in the form of a solid cord of tissue connecting ileum to umbilicus. Synonym: omphalomesenteric cord. (05 Mar 2000) |
| vitelline duct | The narrow tube connecting the yolk sac with the midgut of the embryo; persistence of all or part of it in post-foetal life produces abnormalities, of which the commonest is meckel's diverticulum. (12 Dec 1998) |
| vitelline fistula | A fistula between the umbilicus and the terminal ileum along the course of a persistent vitelline cord. See: Meckel's diverticulum. (05 Mar 2000) |
| vitelline layer of egg | <zoology> The membrane, usually of protein fibres, immediately outside the plasmalemma of the ovum and the earlier stages of the developing embryo. Its structure and composition vary in differing animal groups. (18 Nov 1997) |
| vitelline membrane | <cell biology> The plasma membrane of the egg. (12 Dec 1998) |
| Vitelline pole | <embryology> The vegetative pole of an ovum. (05 Mar 2000) |
| vitelline reservoir | In cestodes and trematodes, a common chamber receiving vitelline (yolk) material from the two vitelline ducts; the yolk material then passes into the ootype to surround the ovum with nutritive vitelline granules that are enclosed by a characteristically formed eggshell. Synonym: vitelline reservoir. (05 Mar 2000) |
| vitelline sac | <embryology, ornithology> One of the set of extra embryonic membranes, growing out from the gut over the yolk surface, in birds formed from the splanchnopleure, an outer layer of splanchnic mesoderm and an inner layer of endoderm. (18 Nov 1997) |
| vitelline vein | <anatomy, vein> A vein returning blood from the yolk sac to the embryo. Synonym: vena vitellina. (05 Mar 2000) |
| vitelline vessels | See: vitelline artery, vitelline vein. (05 Mar 2000) |
| adrenal cyst | <radiology> Same characteristics as renal cysts, but less common, thick wall, septations, calcifications suggests pseudocyst (12 Dec 1998) |
| adventitious cyst | 1. An accumulation of fluid in a cystlike loculus, but without an epithelial or other membranous lining. Synonym: adventitious cyst, false cyst. 2. A cyst whose wall is formed by a host cell and not by a parasite. 3. A mass of 50 or more Toxoplasma bradyzoites, found within a host cell, frequently in the brain; formerly called a pseudocyst, but now considered a true cyst enclosed in its own membrane within the host cell that may rupture to release particles that form new cysts, and apparently is infective to another vertebrate host. See: bradyzoite. Origin: pseudo-+ G. Kystis, bladder (05 Mar 2000) |
| allantoic cyst | Cyst occurring in a persistent portion of the urachus, presenting as an extraperitoneal mass in the umbilical region. It is characterised by abdominal pain, and fever if infected. It may rupture, leading to peritonitis, or it may drain through the umbilicus. (12 Dec 1998) |
| vitelline cyst |
A congenital cyst of the gastrointestinal canal. Lined with ciliated epithelium, it is the remains of the omphalomesenteric duct.
