| heart septal defects, ventricular | Congenital defects in the septum between the cardiac ventricles, most often due to failure of the bulbar septum to completely close the interventricular foramen. (12 Dec 1998) |
|---|---|
| endocardial cushion defects | A spectrum of septal defects associated with persistence of the embryonic atrioventricular canal due to incomplete growth and fusion of the endocardial cushion. (12 Dec 1998) |
| furcation defects | Conditions in which a bifurcation or trifurcation of the molar tooth root becomes denuded as a result of periodontal disease. It may be followed by tooth mobility, temperature sensitivity, pain, and alveolar bone resorption. (12 Dec 1998) |
| artificial neural net | Artificial Neural Nets (ANN) are computer models of biological nerve cell networks. (09 Oct 1997) |
| musculoskeletal, neural, and ocular physiology | Activities and functions of the musculoskeletal system, the nervous system, and the eye and their parts. (12 Dec 1998) |
| neural | 1. Pertaining to a nerve or to the nerves. 2. Situated in the region of the spinal axis, as the neutral arch. Origin: L. Neuralis, Gr. Neuron = nerve (18 Nov 1997) |
| neural arch | The posterior projection from the body of a vertebra that encloses the vertebral foramen; it consists of paired pedicles and laminae; the spinous, transverse, and articular processes arise from the arch. In aggregate, the venous arches-and the ligamenta flava that unite them-form the posterior wall of the vertebral (spinal) canal. Synonym: arcus vertebrae, neural arch. (05 Mar 2000) |
| neural axis | The central nervous system; the brain and spinal cord. Synonym: encephalomyelonic axis, neural axis. (05 Mar 2000) |
| neural canal | The canal within the embryonic neural tube; the primordium of the central canal. (05 Mar 2000) |
| neural cell adhesion molecule | See: NCAM. (18 Nov 1997) |
| neural crest | A group of embryonic cells that separate from the neural plate during neurulation and migrate to give several different lineages of adult cells: the spinal and autonomic ganglia, the glial cells of the peripheral nervous system and nonneuronal cells, such as chromaffin cells, melanocytes and some haemopoietic cells. (18 Nov 1997) |
| neural crest syndrome | <syndrome> Syndrome consisting of loss of pain sensibility, autonomic dysfunction, pupillary abnormalities, neurogenic anhidrosis, vasomotor instability, aplasia of dental enamel, meningeal thickening, hyperflexion, and a degree of albinism; may reflect developmental abnormalities of the neural crest. (05 Mar 2000) |
| neural cyst | A circumscribed distention of some portion of the central canal of the spinal cord or of the cerebral ventricles. Synonym: neural cyst. (05 Mar 2000) |
| neural factor | A protein that can induce the formation of notochord tissue in embryos. (05 Mar 2000) |
| neural fold | A crease that forms in the neural plate during neurulation. (18 Nov 1997) |
