| arteriae gastricae breves | Four or five small arteries given off from the splenic, passing via the gastrosplenic ligament to the fundus of the stomach along the greater curvature, and anastomosing with the other arteries in that region. Synonym: arteriae gastricae breves, vasa brevia. (05 Mar 2000) |
|---|---|
| venae gastricae breves | Small vessels that drain the fundus and left portion of the stomach wall and empty into the splenic vein. Synonym: venae gastricae breves. (05 Mar 2000) |
| gyri breves insulae | Several short, radiating gyri converging toward the base of the insula, composing the anterior two-thirds of the insular cortex. Synonym: gyri breves insulae. (05 Mar 2000) |
| musculi levatores costarum breves | Origin, the transverse processes of last cervical and eleven thoracic vertebrae; insertion ribs immediately below, between angle and tubercle. Synonym: musculi levatores costarum breves. (05 Mar 2000) |
| fibrae arcuatae cerebri | Short association fibres that connect adjacent gyri in the cerebral cortex. Synonym: fibrae arcuatae cerebri. (05 Mar 2000) |
| fibrae arcuatae externae | They include: 1) dorsal external arcuate fibres that arise from cells in the accessory or lateral cuneate nucleus and pass to the cerebellum; 2) ventral external arcuate fibres that arise from the arcuate nuclei at the base of the medulla oblongata and pass around the lateral surface of the medulla; both enter the cerebellum as components of the restiform portion of the inferior cerebellar peduncle. Synonym: fibrae arcuatae externae. (05 Mar 2000) |
| fibrae arcuatae internae | <anatomy> Fibres that arise in the cuneate and gracile nuclei, pass in a curving course across the midline of the medulla oblongata, and form the contralateral medial lemniscus. It also designates other fibres such as those of the olivocerebellar tract that arch through the substance of the medulla and form sensory decussation. Synonym: fibrae arcuatae internae. (05 Mar 2000) |
| fibrae circulares | The circular fibres of the ciliary muscle. Synonym: fibrae circulares, Muller's fibres, Muller's muscle, Rouget's muscle. (05 Mar 2000) |
| fibrae corticonucleares | <physiology> Descriptive term connotating fibres from a cortical structure (cerebral or cerebellar) passing to subcortical cell groups; fibres comprising the tractus corticobulbaris; cerebellar corticonuclear fibres (Purkinje cell axons to the cerebellar nuclei). Synonym: fibrae corticonucleares. (05 Mar 2000) |
| fibrae corticopontinae | <physiology> The fibres that compose the corticopontine tract. Synonym: fibrae corticopontinae. (05 Mar 2000) |
| fibrae corticoreticulares | <physiology> Corticofugal fibres distributed to the reticular formation of the mesencephalon and rhombencephalon. See: corticobulbar fibres. Synonym: fibrae corticoreticulares. (05 Mar 2000) |
| fibrae corticospinales | The fibres that compose the pyramidal tract (corticospinalis). Synonym: fibrae corticospinales, corticospinal fibres, fibrae pyramidales. (05 Mar 2000) |
| fibrae dentatorubrales | Nerve fibres arising in the dentate nucleus of the cerebellum and projecting, via the superior cerebellar peduncle and its decussation, to the contralateral red nucleus of the midbrain. Synonym: fibrae dentatorubrales. (05 Mar 2000) |
| fibrae intercrurales | Horizontal arched fibres that pass from the inguinal ligament across the medial and lateral crura of the superficial inguinal ring. Synonym: fibrae intercrurales, intercolumnar fasciae, intercolumnar fibres. (05 Mar 2000) |
| fibrae lentis | <biology, ophthalmology, physiology> The elongated cells of ectodermal origin forming the substance of the crystalline lens of the eye. Synonym: fibrae lentis. (05 Mar 2000) |
