| circular fibres | The circular fibres of the ciliary muscle. Synonym: fibrae circulares, Muller's fibres, Muller's muscle, Rouget's muscle. (05 Mar 2000) |
|---|---|
| mineral fibres | Long, pliable, cohesive natural or manufactured filaments of various lengths. They form the structure of some minerals. The medical significance lies in their potential ability to cause various types of pneumoconiosis (e.g., asbestosis) after occupational or environmental exposure. (12 Dec 1998) |
| climbing fibres | Nerve fibre's in the cerebellar cortex that synapse upon smooth branchlets of Purkinje cell dendrites. (05 Mar 2000) |
| pilomotor fibres | Nerve fibre's that innervate the erector muscles of hair follicles responsible for piloerection. (05 Mar 2000) |
| Weitbrecht's fibres | One of several longitudinal folds of the articular capsule of the hip joint reflected onto the femoral neck deep to which the retinacular branches of the medial femoral circumflex artery pass to reach the femoral head. Synonym: retinaculum capsulae articularis coxae, Weitbrecht's fibres. (05 Mar 2000) |
| commissural fibres | Nerve fibre's crossing the midline and connecting two corresponding parts or regions of the nervous system. (05 Mar 2000) |
| 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) |
| motor fibres | Nerve fibre's that transmit impulses that activate effector cells, e.g., in muscle or gland tissue. (05 Mar 2000) |
| Muller's fibres | Sustentacular neuroglial cells of the retina running through the thickness of the retina from the internal limiting membrane to the bases of the rods and cones where they form a row of junctional complexes. Synonym: Muller's radial cells, sustentacular fibres of retina. (05 Mar 2000) |
| polar fibres | Those fibres of the mitotic spindle extending from the two poles of the spindle toward the equator. Compare: astral fibres, kinetochore fibres. (05 Mar 2000) |
| corticospinal fibres | The fibres that compose the pyramidal tract (corticospinalis). Synonym: fibrae corticospinales, corticospinal fibres, fibrae pyramidales. (05 Mar 2000) |
| corticothalamic fibres | A general term designating nerve fibres originating from any area of the cerebral cortex and terminating in the nuclei of the thalamus. (05 Mar 2000) |
| postganglionic fibres | A fibre whose cell body is located in an autonomic (motor) ganglion and whose peripheral process will terminate on smooth muscle, cardiac muscle, or glandular epithelium; associated with sympathetic or parasympathetic parts of the autonomic nervous system. (05 Mar 2000) |
| precollagenous fibres | Immature, argyrophilic fibre's. (05 Mar 2000) |
