| vessel | Water conducting system in the xylem, consisting of a column of cells (vessel elements) whose end walls have been perforated or totally degraded, resulting in an uninterrupted tube. (18 Nov 1997) |
| vessel, afferent | A vessel carrying blood toward the heart. A vein or venule. Afferent hails from the latin ad meaning toward + ferre, to bear. The opposite of an afferent vessel is an efferent vessel, an artery or arteriole. (12 Dec 1998) |

| vessel element | Part of a xylem vessel in a higher plant, arising from a single cell. The end walls are perforated and may completely disappear, giving rise to a continuous tube. The remaining walls are thickened and lignified and there is no protoplast. (18 Nov 1997) |
| chyle vessel | 1. Pertaining to, or resembling, milk; milky; as, the lacteal fluid. 2. <anatomy> Pertaining to, or containing, chyle; as, the lacteal vessels. Origin: L. Lacteus milky, fr. Lac, lactis, milk. Cf. Galaxy, Lettuce. <anatomy> One of the lymphatic vessels which convey chyle from the small intestine through the mesenteric glands to the thoracic duct; a chyliferous vessel.

| pineal region tumours | Type of brain tumours. (12 Dec 1998) |
| pineal tumours | <radiology> SIGNS: aqueductal obstruction most likely to be hydrocephalus, paralysis of upward gaze (due to pressure on quarigeminal plate), precocious puberty, symptoms of hypothalamic, thalamic, cerebellar or pyramidal lesion TYPES: germ-cell (teratoid) tumours, teratoma, germinoma / atypical teratoma, endodermal sinus (yolk sac) tumour, choriocarcinoma, pineal-cell tumours, pineocytoma, pineo---, others, glioma, ganglioneuroma, ganglioglioma (12 Dec 1998) |
| collateral vessel | A branch of an artery running parallel with the parent trunk, a vessel that runs in parallel with another vessel, nerve, or other long structure. Synonym: vas collaterale. (05 Mar 2000) |
| plant tumours | A localised proliferation of plant tissue forming a swelling or outgrowth, commonly with a characteristic shape and unlike any organ of the normal plant. Plant tumours or galls usually form in response to the action of a pathogen or a pest. (12 Dec 1998) |
| containment vessel | <radiobiology> Gas-tight shell or other enclosure around a fusion (or fission) reactor, to prevent accidental leakage of radioactive contents. (09 Oct 1997) |
| coronary vessel anomalies | Defects of coronary arteries or veins including anomalous origin, arteriovenous fistula or aneurysm, myocardial bridging, or other abnormalities of structure or development. (12 Dec 1998) |
| posterior fossa tumours | <radiology> Midline, medulloblastoma (hyperdense, enhances), astrocytoma (hypodense, enhances), 4th ventricle, ependymoma (most common, slow-growing, expands ventricle), medulloblastoma (usually obliterates ventricular cavity), choroid plexus papilloma (more common in lateral ventricles) (12 Dec 1998) |
| primitive neuroectodermal tumours | A type of brain tumour. Prenatal diagnosis: diagnosis before birth. Methods for prenatal diagnosis include ultrasound (of the uterus, placenta and developing foetus), chorionic villus sampling to obtain tissue for chromosome or biochemical analysis, amniocentesis to obtain amniotic fluid for the analysis of chromosmes, enzymes, DNA, etc. A growing number of birth defects and diseases are now amenable to prenatal diagnosis. Also called antenatal diagnosis. (12 Dec 1998) |
| nerve sheath tumours | Tumours arising in the sheath surrounding the axon of some nerve cells and formed by the plasma membrane of schwann cells in the peripheral nervous sytem and by oligodendrocytes in the central nervous system. Neurofibromas and neurilemmomas are the most commonly occurring tumours of this type. (12 Dec 1998) |
