| Virchow's corpuscles | Connective tissue cells found between the laminae of fibrous tissue in the cornea. Synonym: Toynbee's corpuscles, Virchow's cells, Virchow's corpuscles. (05 Mar 2000) |
|---|
| Virchow-Hassall bodies | Small spherical bodies of keratinised and usually squamous epithelial cells arranged in a concentric pattern around clusters of degenerating lymphocytes, eosinophils, and macrophages; found in the medulla of the lobules of the thymus. Synonym: Hassall's bodies, Hassall's concentric corpuscle, Virchow-Hassall bodies. (05 Mar 2000) |
|---|---|
| Virchow-Holder angle | An angle formed by the meeting of a line drawn from the middle of the nasofrontal suture to the base of the anterior nasal spine with a line drawn from this last point to the centre of the external auditory meatus. Synonym: Virchow-Holder angle. (05 Mar 2000) |
| Virchow-Robin space | A tunnel-like extension of the subarachnoid space surrounding blood vessels that pass into the brain or spinal cord from the subarachnoid space; the lining of the channel is composed of pia and glial feet of astrocytes; a continuation of the space around capillaries and nerve cells probably does not occur. Synonym: His' perivascular space. (05 Mar 2000) |
| Virchow, Rudolf | <person> German pathologist and politician, 1821-1902. See: Virchow's angle, Virchow's cells, Virchow's corpuscles, Virchow's crystals, Virchow's disease, Virchow's law, Virchow's node, Virchow's psammoma, Virchow-Holder angle, Virchow-Hassall bodies, Virchow-Robin space.

| Virchow's angle | An angle formed by the meeting of a line drawn from the middle of the nasofrontal suture to the base of the anterior nasal spine with a line drawn from this last point to the centre of the external auditory meatus. Synonym: Virchow-Holder angle. (05 Mar 2000) |
| Virchow's cells | The lacunae in osseous tissue containing the bone cell's; also the bone cell's themselves. Synonym: corneal corpuscles. (05 Mar 2000) |
| Virchow's crystals | Yellow-brown, amber, or burnt orange crystal's of haematoidin, frequently observed in extravasated blood in tissues. (05 Mar 2000) |
| Virchow's disease | A condition, either congenital or acquired, in which the head is abnormally large; usually applied to an adult skull with a capacity of over 1450 ml. Synonym: leontiasis ossea, macrocephaly, macrocephalia, megacephalia, megalocephaly, megalocephalia, Virchow's disease. Origin: mega-+ G. Kephale, head (05 Mar 2000) |
| Virchow's law | There is no special or distinctive neoplastic cell, inasmuch as the component cells of neoplasms originate from preexisting forms. (05 Mar 2000) |
| Virchow's node | A firm supraclavicular lymph node, especially on the left side, sufficiently enlarged that it is palpable from the cutaneous surface; such a lymph node is so termed because it may be the first recognised presumptive evidence of a malignant neoplasm in one of the viscera. A signal node that is known to contain a metastasis from a malignant neoplasm is sometimes designated by an old eponym, Troisier's ganglion. Synonym: jugular gland, Virchow's node. (05 Mar 2000) |
| Virchow's psammoma | <tumour> A firm cellular neoplasm derived from fibrous tissue of the meninges, choroid plexus, and certain other structures associated with the brain, characterised by the formation of multiple, discrete, concentrically laminated, calcareous bodies (psammoma bodies); most of these neoplasms are histologically benign, but may lead to severe symptoms as a result of compressing the brain. Synonym: angiolithic sarcoma, sand tumour, Virchow's psammoma. (05 Mar 2000) |
| articular corpuscles | Encapsulated nerve terminations within joint capsules. Synonym: corpuscula articularia. (05 Mar 2000) |
| bulboid corpuscles | Nerve terminals in skin, mouth, conjunctiva, and other parts, consisting of a laminated capsule of connective tissue enclosing the terminal, branched, convoluted ending of an afferent nerve fibre; generally believed to be sensitive to cold. Synonym: corpuscula bulboidea, bulboid corpuscles. (05 Mar 2000) |
| pacchionian corpuscles | Tufted prolongations of pia-arachnoid, composed of numerous arachnoid villi that penetrate dural venous sinuses and effect transfer of cerebrospinal fluid to the venous system. at advanced age these are more numerous and tend to calcify. Synonym: granulationes arachnoideales, arachnoidal granulations, pacchionian bodies, pacchionian corpuscles, pacchionian glands, pacchionian granulations. (05 Mar 2000) |
| pacinian corpuscles | Rapidly adapting mechanoreceptors found in subcutaneous tissue beneath both hairy and glabrous skin. Pacinian corpuscles contain an afferent nerve fibre surrounded by a capsule with multiple concentric layers. They have large receptive fields and are most sensitive to high-frequency stimuli, such as vibration. (12 Dec 1998) |
