| MF | Mossy Fiber |
| mossy fibres | Highly branched nerve fibre's in the cerebellar cortex that terminate in rosette formations and synapse upon granule cell dendrites. (05 Mar 2000) |
|---|---|
| mossy fibres, hippocampal | Axons of certain cells in the dentate gyrus. They project to the polymorphic layer of the dentate gyrus and to the proximal dendrites of pyramidal cells of the hippocampus. These mossy fibres should not be confused with mossy fibres that are cerebellar afferents (see nerve fibres). (12 Dec 1998) |
| mossy | 1. Overgrown with moss; abounding with or edged with moss; as, mossy trees; mossy streams. "Old trees are more mossy far than young." (Bacon) 2. Resembling moss; as, mossy green. Origin: Mossier; Mossiest. Source: Websters Dictionary (01 Mar 1998) |
|---|---|
| mossy cell | One of the two types of neuroglia cell's, consisting of a rather large body with numerous short branching processes. (05 Mar 2000) |
| mossy foot | A profuse velvety papillomatous growth that develops large warty projections; caused by chronic lymphedema and stasis with maceration and associated infection. Synonym: lymphedematous keratoderma, lymphostatic verrucosis. (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) |
