| dental fibres | <dentistry> The processes of the pulpal cells, the odontoblasts, which extend in radial fashion through the dentin to the dentoenamel junction and are contained within the dentinal tubules. The intertubular fine collagenous fibre's that with the dentinal ground substance infiltrated with calcium salts constitutes the dentinal matrix. Synonym: Tomes' fibres. (05 Mar 2000) |
|---|
| superior dental branches of superior dental plexus | Branches passing from the superior dental plexus to the roots of the teeth of the upper jaw. Synonym: rami dentales superiores plexus dentalis superioris. (05 Mar 2000) |
|---|---|
| inferior dental branches of inferior dental plexus | Branches passing from the inferior dental plexus to the roots of the teeth of the lower jaw. Synonym: rami dentales inferiores plexus dentalis inferioris. (05 Mar 2000) |
| accelerator fibres | Postganglionic sympathetic nerve fibre's originating in the superior, middle, and inferior cervical ganglia of the sympathetic trunk, conveying nervous impulses to the heart that increase the rapidity and force of the cardiac pulsations. Synonym: augmentor fibres. (05 Mar 2000) |
| adrenergic fibres | Nerve fibres liberating catecholamines at a synapse after an impulse. (12 Dec 1998) |
| afferent fibres | Those that convey impulses to a ganglion or to a nerve centre in the brain or spinal cord. (05 Mar 2000) |
| A fibres | Myelinated nerve fibre's in somatic nerves, measuring 1 to 22 um in diameter, conducting nerve impulses at a rate of 6 to 120 m/sec. (05 Mar 2000) |
| alpha fibres | Large somatic motor or proprioceptive nerve fibre's conducting impulses at rates near 100 m/sec. (05 Mar 2000) |
| anastomosing fibres | Anastomotic fibres, individual fibre's passing from one nerve trunk or muscle bundle to another. (05 Mar 2000) |
| arcuate fibres | Nervous or tendinous fibre's passing in the form of an arch from one part to another. See: arcuate fibres of cerebrum, external arcuate fibres, internal arcuate fibres. (05 Mar 2000) |
| arcuate fibres of cerebrum | Short association fibres that connect adjacent gyri in the cerebral cortex. Synonym: fibrae arcuatae cerebri. (05 Mar 2000) |
| association fibres | Nerve fibre's interconnecting subdivisions of the cerebral cortex of the same hemisphere or different segments of the spinal cord on the same side. Synonym: endogenous fibres, intrinsic fibres. (05 Mar 2000) |
| astral fibres | Fibre's (fibrils) radiating from the centrosphere toward the periphery of the cell as seen with a light microscope; revealed as microtubules under the electron microscope. Compare: kinetochore fibres, polar fibres. (05 Mar 2000) |
| augmentor fibres | Postganglionic sympathetic nerve fibre's originating in the superior, middle, and inferior cervical ganglia of the sympathetic trunk, conveying nervous impulses to the heart that increase the rapidity and force of the cardiac pulsations. Synonym: augmentor fibres. (05 Mar 2000) |
| autonomic fibres, postganglionic | Nerve fibres which project from cell bodies of autonomic ganglia to synapses on target organs. (12 Dec 1998) |
| autonomic fibres, preganglionic | Nerve fibres which project from the central nervous system to autonomic ganglia. In the sympathetic division most preganglionic fibres originate with neurons in the intermediolateral column of the spinal cord, exit via ventral roots from upper thoracic through lower lumbar segments, and project to the paravertebral ganglia; there they either terminate in synapses or continue through the splanchnic nerves to the prevertebral ganglia. In the parasympathetic division the fibres originate in neurons of the brainstem and sacral spinal cord. In both divisions the principal transmitter is acetylcholine but peptide cotransmitters may also be released. (12 Dec 1998) |
