| fibrillary | 1. Relating to a fibril. 2. <biology> Denoting the fine rapid contractions or twitchings of fibres or of small groups of fibres in skeletal or cardiac muscle. Synonym: filar. (05 Mar 2000) |
| fibrillary astrocytoma | <tumour> Astrocytoma derived from fibrillary astrocytes. (05 Mar 2000) |
| fibrillary chorea | Continuous involuntary quivering or rippling of muscles at rest, caused by spontaneous, repetitive firing of groups of motor unit potentials. Synonym: fibrillary chorea, kymatism, Morvan's chorea. Origin: myo-+ G. Kyma, wave (05 Mar 2000) |
| fibrillary contractions | <physiology> Contraction's occurring spontaneously in individual muscle fibres; they are seen commonly a few days after damage to the motor nerves supplying the muscle, and this type of activity is distinguished from fasciculation, which is related to activation of motor units. (05 Mar 2000) |
| fibrillary neuroma | plexiform neurofibroma |
| fibrillary waves | The waves of atrial flutter usually best seen in ECG leads 2, 3, and AVF. (A small f indicates atrial fibrillation). Synonym: fibrillary waves, fibrillatory waves, flutter-fibrillation waves. (05 Mar 2000) |
| Alzheimer type I astrocyte | Enlarged frequently multinucleated astrocytes, seen in progressive multifocal leukoencephalopathy. (05 Mar 2000) |
| Alzheimer type II astrocyte | Enlarged astrocytes with vesicular nuclei and one or more small basophilic nucleoli, seen in hepatocerebral disease and Wilson's disease. (05 Mar 2000) |
| astrocyte | <pathology> A glial cell found in vertebrate brain, named for its characteristic star like shape. Astrocytes lend both mechanical and metabolic support for neurons, regulating the environment in which they function. See: oligodendrocytes. (18 Nov 1997) |
| Cajal's astrocyte stain | <technique> A method for demonstrating astrocytes by impregnation in a solution containing gold chloride and mercuric chloride. (05 Mar 2000) |
| gemistocytic astrocyte | <cell biology> A round to oval astrocyte cell with abundant cytoplasm containing glial filaments and an eccentric nucleus; may contain two nuclei in the cell hypertrophy of astrocytes. Synonym: gemistocyte, gemistocytic cell, reactive astrocyte, reactive cell. (05 Mar 2000) |
| reactive astrocyte | <cell biology> A round to oval astrocyte cell with abundant cytoplasm containing glial filaments and an eccentric nucleus; may contain two nuclei in the cell hypertrophy of astrocytes. Synonym: gemistocyte, gemistocytic cell, reactive astrocyte, reactive cell. (05 Mar 2000) |
| protoplasmic astrocyte | One form of astrocyte, found mainly in gray matter, having few fibrils and numerous branching processes. (05 Mar 2000) |
| type 2 astrocyte | <pathology> A glial cell found in vertebrate brain, named for its characteristic star like shape. Astrocytes lend both mechanical and metabolic support for neurons, regulating the environment in which they function. See: oligodendrocytes. (18 Nov 1997) |
