| Gerdy's fibres | <anatomy> A thickening of the deep fascia in the most distal part of the (base) of the triangular palmar aponeurosis. Synonym: ligamentum metacarpale transversum superficiale, Gerdy's fibres, ligamentum natatorium. (05 Mar 2000) |
|---|---|
| red fibres | Red striated muscle fibre's that are rich in sarcoplasm, myoglobin, and mitochondria; they are smaller in diameter and contract more slowly than white fibre's. (05 Mar 2000) |
| Remak's fibres | A fibre having no myelin covering (CNS); a naked axon; in the PNS represented by all axons lying in troughs in a single Schwann cell (Schwann cell unit); a slow conducting fibre. Synonym: gray fibres, nonmedullated fibres, Remak's fibres. (05 Mar 2000) |
| pectinate fibres | Prominent ridges of atrial myocardium located on the inner surface of much of the right atrium and both auricles. Synonym: musculi pectinati, pectinate fibres. (05 Mar 2000) |
| cerebellohypothalamic fibres | Nerve fibres originating from cells of the cerebellar nuclei and projecting, via the superior cerebellar peduncle, to the contralateral hypothalamus, mainly its dorsal, lateral, and posterior areas and dorsomedial nucleus. (05 Mar 2000) |
| cerebellospinal fibres | Crossed descending fibres originating in the fastigial nucleus of the cerebellum and ending in the spinal cord gray matter at cervical, and possibly lower, levels. (05 Mar 2000) |
| C fibres | Unmyelinated fibre's, 0.4 to 1.2 um in diameter, conducting nerve impulses at a velocity of 0.7 to 2.3 m/sec. (05 Mar 2000) |
| Retzius' fibres | Stiff fibre's in Deiters' cells. (05 Mar 2000) |
| perforating fibres | Bundles of collagenous fibre's that pass into the outer circumferential lamellae of bone or the cementum of teeth. Synonym: Sharpey's fibres. (05 Mar 2000) |
| meridional fibres | The longitudinal fibres of the ciliary muscle. Synonym: fibrae meridionales. (05 Mar 2000) |
| periodontal ligament fibres | The collagen fibre's, running from the cementum to the alveolar bone, that suspend a tooth in its socket; they include apical, oblique, horizontal, and alveolar crest fibre's, indicating that the orientation of the fibre's varies at different levels. (05 Mar 2000) |
| Gratiolet's fibres | The massive, fanlike fibre system passing from the lateral geniculate body of the thalamus to the visual cortex (striate or calcarine cortex, area 17 of Brodmann); the fibres follow the retrolenticular and sublenticular limbs of the internal capsule into the corona radiata but they curve back along the lateral wall of the temporal and occipital horns of the lateral ventricle to the striate cortex on the medial surface and pole of the occipital lobe. Synonym: radiatio optica, geniculocalcarine radiation, geniculocalcarine tract, Gratiolet's fibres, Gratiolet's radiation, occipitothalamic radiation, Wernicke's radiation. (05 Mar 2000) |
| gray fibres | A fibre having no myelin covering (CNS); a naked axon; in the PNS represented by all axons lying in troughs in a single Schwann cell (Schwann cell unit); a slow conducting fibre. Synonym: gray fibres, nonmedullated fibres, Remak's fibres. (05 Mar 2000) |
| periventricular fibres | A heterogeneous system of thin nerve fibres in the periventricular gray matter of the hypothalamus; the dorsal longitudinal fasciculus is a caudal continuation of the system. Synonym: fibrae periventriculares. (05 Mar 2000) |
| cholinergic fibres | Nerve fibres liberating acetylcholine at the synapse after an impulse. (12 Dec 1998) |
