|---|---|
| ventral decubitus | Pressure sores (decubitus ulceration) occurring in ventral locations, such as the abdominal wall or the anterior surface of an extremity. (05 Mar 2000) |
| ventral glands | <entomology> Insect structures that originate from the ectoderm of the ventrocaudal part of the head and serve as a source of ecdysone. Synonym: peritracheal glands, prothoracic glands, thoracic glands, ventral glands. (05 Mar 2000) |
| ventral hernia | An abdominal incisional hernia. (05 Mar 2000) |
| ventral horn | The anterior or frontal division of the lateral ventricle of the brain, extending forward from Monro's interventricular foramen. See: lateral ventricle. (05 Mar 2000) |
| ventral mesogastrium | The primitive midline mesentery extending between future stomach and proximal duodenum and the anterior abdominal wall superior to the umbilicus (umbilical vein). The liver develops within it, and consequently the lesser omentum, coronary and falciform ligaments are derivatives of it. The umbilical vein runs in its caudal free edge, becoming the postnatal round ligament of the liver. (05 Mar 2000) |
| ventral nervous system defective | <molecular biology> A Drosophila gene encoding an integral membrane glycoprotein related to amyloidogenic glycoprotein. (12 Jan 1998) |
| ventral pancreas | That portion of the primordium of the pancreas that develops, together with the hepatic diverticulum, as a ventral bud from the foregut endoderm. (05 Mar 2000) |
| ventral part of pons | The large ventral part of the pons occupied by the nuclei pontis, traversed longitudinally by corticopontine, corticobulbar, and corticospinal fibres, and transversely by pontocerebellar fibres. Pontocerebellar fibres converging laterally form the middle cerebellar peduncle or brachium pontis. Synonym: pars ventralis pontis, anterior part of pons, basilar part of pons, pars basilaris pontis. (05 Mar 2000) |
| ventral plate | Ventral midline thinning of the developing neural tube, a continuity between the basal laminae of either side; opposite of roof plate. Synonym: ventral plate. (05 Mar 2000) |
| ventral plate of neural tube | The ventral division of the lateral walls of the neural tube in the embryo; it contains neuroblasts giving rise to somatic and visceral motor neurons. Synonym: lamina basalis, basal plate of neural tube, lamina ventralis, ventral plate of neural tube. (05 Mar 2000) |
| ventral primary rami of cervical spinal nerves | See: ventral primary ramus of spinal nerve. Synonym: rami ventrales nervorum cervicalium. (05 Mar 2000) |
| ventral primary rami of lumbar spinal nerves | See: ventral primary ramus of spinal nerve. Synonym: rami ventrales nervorum lumbalium. (05 Mar 2000) |
| ventral primary rami of sacral spinal nerves | See: ventral primary ramus of spinal nerve. Synonym: rami ventrales nervorum sacralium. (05 Mar 2000) |
| ventral primary ramus of spinal nerve | <anatomy, nerve> The larger, anterolaterally-directed major terminal branch (with the dorsal primary ramus) of all 31 pairs of mixed spinal nerves, formed at the intervertebral foramen. Most ventral primary rami, especially those involved in the innervation of the limbs, participate in the formation of the major nerve plexuses (cervical, brachial, and lumbosacral) and lose their identities. Most in the thoracic region, however, remain separate from adjacent rami to become the intercostal and subcostal nerves. Ventral primary rami provide innervation to the anterolateral body wall and trunk. Nomina Anatomica lists ventral primary rami as "rami ventrales" for each group of spinal nerves: 1) cervical (nervorum cervicalium ), 2) thoracic (nervorum thoracicorum ), 3) lumbar (nervorum lumbalium ), 4) sacral (nervorum sacralium )m, and 5) coccygeal (nervi coccygei ). Synonym: ramus ventralis nervi spinalis, anterior primary division. (05 Mar 2000) |
