| 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) |

| Weitbrecht's cord | A slender band extending from the lateral part of the coronoid process of the ulna distad and laterad to the radius immediately distal to the bicipital tuberosity. Synonym: chorda obliqua, oblique cord, round ligament of elbow joint, Weitbrecht's cord, Weitbrecht's ligament. (05 Mar 2000) |
| Weitbrecht's foramen | An opening in the articular capsule of the shoulder joint, communicating with the subtendinous bursa of the subscapularis muscle. (05 Mar 2000) |
| Weitbrecht's ligament | A slender band extending from the lateral part of the coronoid process of the ulna distad and laterad to the radius immediately distal to the bicipital tuberosity. Synonym: chorda obliqua, oblique cord, round ligament of elbow joint, Weitbrecht's cord, Weitbrecht's ligament. (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) |
