| bones of visceral cranium | The facial skeleton, consisting of bones situated between the cranial base and the mandibular region. While some consider the facial bones to comprise the hyoid, palatine, and zygomatic bones, mandible, and maxilla, others include also the lacrimal and nasal bones, inferior nasal concha, and vomer but exclude the hyoid bone.

| general visceral efferent column | A column of gray matter in the hindbrain and spinal cord of the embryo, represented in the adult by the dorsal nucleus of the vagus, the superior and inferior salivatory and Edinger-Westphal nuclei and the visceral motor neurons of the spinal cord.

| visceral | <anatomy> From viscus, pertaining to a viscus. Origin: L. Visceralis (13 Oct 1997) |
| visceral anaesthesia | Loss of sensation in areas of the visceral peritoneum innervated by the splanchnic nerves. Synonym: visceral anaesthesia. (05 Mar 2000) |
| visceral arches | Typically, 6 arch's in vertebrates; in the lower vertebrates, they bear gills; in the higher vertebrates, they appear transiently and give rise to specialised structures in the head and neck. Synonym: pharyngeal arches, visceral arches. (05 Mar 2000) |
| visceral brain | Collective term denoting a heterogeneous array of brain structures at or near the edge (limbus) of the medial wall of the cerebral hemisphere, in particular the hippocampus, amygdala, and fornicate gyrus; the term is often used so as to include also the interconnections of these structures, as well as their connections with the septal area, the hypothalamus, and a medial zone of mesencephalic tegmentum. By way of the latter connections, the limbic system exerts an important influence upon the endocrine and autonomic motor system's; its functions also appear to affect motivational and mood states. Synonym: visceral brain. (05 Mar 2000) |
| visceral cavity | The celom or one of the body cavity's derived from it. Synonym: visceral cavity. (05 Mar 2000) |
| 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) |
