| visceral cleft | Any cleft between two branchial (visceral) arches in the embryo. (05 Mar 2000) |
|---|---|
| visceral crises | Attacks of severe, spreading epigastric pain that occur in patients with tabetic neurosyphilis. (05 Mar 2000) |
| visceral disease virus | <virology> Probably the most widespread of the Herpetoviridae group. Infected cells enlarge and have a characteristic inclusion body (composed of virus particles) in the nucleus. Causes disease only in utero (leading to abortion or stillbirth or to various congenital defects), although can be opportunistic in the immunocompromised host. Patients who have been exposed to the virus will remain cytomegalovirus IgG positive. Acronym: CMV (30 Sep 1997) |
| visceral disorder | Nomenclature used in reference to psychosomatic disorder. (05 Mar 2000) |
| visceral epilepsy | Epilepsy, usually psychomotor, in which the attacks are initiated by visceral symptoms or sensations; most cases have their focus in the temporal lobe. (05 Mar 2000) |
| visceral inversion | A transposition of the viscera, e.g., the liver developing on the left side or the heart on the right. Synonym: visceral inversion. (05 Mar 2000) |
| visceral larva migrans | A disease, chiefly of children, caused by ingestion of infective ova of Toxocara canis, less commonly by other ascarid nematodes not adapted to humans, whose larvae hatch in the intestine, penetrate the gut wall, and wander in the viscera (chiefly the liver) for periods of up to 18 or 24 months; may be asymptomatic or may be marked by hepatomegaly (with granulomatous lesions caused by encapsulated larvae in the enlarged liver), pulmonary infiltration, fever, cough, hyperglobulinaemia, and sustained high eosinophilia. (05 Mar 2000) |
| visceral layer | The inner layer of an enveloping sac or bursa which lines the outer surface of the enveloped structure, as opposed to the parietal layer which lines the walls of the occupied space or cavity. The visceral layer is usually thin, delicate and not apparent as being separate, but rather appears to be the outer surface of the structure itself. Synonym: lamina visceralis. (05 Mar 2000) |
| visceral layer of serous pericardium | The inner part of the serous pericardium applied directly on the heart. Synonym: epicardium, lamina visceralis pericardii. (05 Mar 2000) |
| visceral layer of tunica vaginalis of testis | The inner part of the tunica vaginalis testis applied directly to the testis and epididymis. Synonym: lamina visceralis tunicae vaginalis testis. (05 Mar 2000) |
| visceral leishmaniasis | A chronic disease, occurring in India, Assam, China, the area formerly known as the Mediterranean littoral areas, the Middle East, India, Pakistan, China, South and Central America, Asia, Africa caused by Leishmania donovani and transmitted by the bite of an appropriate species of sandfly of the genus Phlebotomus or Lutzomyia; the organisms grow and multiply in macrophages, eventually causing them to burst and liberate amastigote parasites which then invade other macrophages; proliferation of macrophages in the bone marrow causes crowding out of erythroid and myeloid elements, resulting in leukopenia, and anaemia, splenomegaly, and hepatomegaly which are characteristic, along with enlargement of lymph nodes; fever, fatigue, malaise, and secondary infections also occur; different strains of leishmaniasis donovani occur; leishmaniasis infantum in Eurasia, leishmaniasis chagasi in Latin America. Synonym: Assam fever, black sickness, Burdwan fever, cachectic fever, Dumdum fever, kala azar, tropical splenomegaly. (05 Mar 2000) |
| visceral lymph nodes | The lymph nodes draining the viscera of the abdomen or of the pelvis. Synonym: nodi viscerales, visceral nodes. (05 Mar 2000) |
| visceral lymphomatosis | See: avian lymphomatosis. (05 Mar 2000) |
| visceral mesoderm | The splanchnic mesoderm or the branchial mesoderm. (05 Mar 2000) |
| visceral muscle | <anatomy, pathology, physiology> Muscle tissue in vertebrates made up from long tapering cells that may be anything from 20-500m long. Smooth muscle is generally involuntary and differs from striated muscle in the much higher actin/myosin ratio, the absence of conspicuous sarcomeres and the ability to contract to a much smaller fraction of its resting length. Smooth muscle cells are found particularly in blood vessel walls, surrounding the intestine (particularly the gizzard in birds) and in the uterus. The contractile system and its control resemble those of motile tissue cells (e.g. Fibroblasts, leucocytes) and antibodies against smooth muscle myosin will cross react with myosin from tissue cells, whereas antibodies against skeletal muscle myosin will not. See: dense bodies. (18 Nov 1997) |
