| gracile fasciculus | The smaller medial subdivision of the posterior funiculus. Synonym: fasciculus gracilis. (05 Mar 2000) |
|---|---|
| perpendicular fasciculus | A bundle of association fibres running vertically and interconnecting regions of the temporal, occipital, and parietal lobes. (05 Mar 2000) |
| Meynert's fasciculus | A compact bundle of fibres arising in the habenula and passing ventralward to the interpeduncular nucleus at the base of the midbrain; part of its fibres bypass this nucleus and terminate in the raphe nuclei of the caudal mesencephalic tegmentum. Synonym: fasciculus retroflexus, habenulointerpeduncular tract, Meynert's fasciculus, Meynert's retroflex bundle. (05 Mar 2000) |
| round fasciculus | A slender, compact fibre bundle extending longitudinally through the dorsolateral region of the medullary tegmentum, surrounded by the nucleus of the solitary tract, below the obex decussating over the central canal, and descending over some distance into the upper cervical segments of the spinal cord. It is composed of primary sensory fibres that enter with the vagus, glossopharyngeal, and facial nerves, and in part convey information from stretch receptors and chemoreceptors in the walls of the cardiovascular, respiratory, and intestinal tracts; in rostral parts of the tract impulses are generated by the receptor cells of the taste buds in the mucosa of the tongue. Its fibres are distributed to the nucleus of the solitary tract. Synonym: tractus solitarius, fasciculus rotundus, fasciculus solitarius, funiculus solitarius, Gierke's respiratory bundle, Krause's respiratory bundle, round fasciculus, solitary bundle, solitary fasciculus. (05 Mar 2000) |
| wedge-shaped fasciculus | The larger lateral subdivision of the posterior funiculus. Synonym: fasciculus cuneatus, Burdach's column, Burdach's fasciculus, Burdach's tract, cuneate funiculus, wedge-shaped fasciculus. (05 Mar 2000) |
| cuneate fasciculus | The larger lateral subdivision of the posterior funiculus. Synonym: fasciculus cuneatus, Burdach's column, Burdach's fasciculus, Burdach's tract, cuneate funiculus, wedge-shaped fasciculus. (05 Mar 2000) |
| semilunar fasciculus | A compact bundle composed of descending branches of posterior root fibres located near the border between the fasciculi gracilis and cuneatus of the cervical and thoracic spinal cord; it corresponds to the septomarginal fasciculus, Hoche's tract, or oval area of Flechsig in the lumbar, and to the triangle of Philippe-Gombault in the sacral spinal segments; like these, it can be demonstrated only in cases of demyelination resulting from dorsal root lesions. Synonym: fasciculus semilunaris, fasciculus interfascicularis, comma bundle of Schultze, comma tract of Schultze, interfascicular fasciculus. (05 Mar 2000) |
| hooked fasciculus | A band of long association fibres reciprocally connecting the frontal and temporal lobes of the cerebrum, running caudally through the white matter of the frontal lobe, sharply curving ventrally under the stem of the sylvian fissure, and then fanning out to the cortex of the anterior half of the superior and middle temporal gyri. Synonym: fasciculus uncinatus, arcuate fasciculus, frontotemporal tract, hooked fasciculus, temporofrontal tract. (05 Mar 2000) |
| septomarginal fasciculus | Septomarginal fasciculus or tract. Synonym: fasciculus septomarginalis. (05 Mar 2000) |
| slender fasciculus | gracile fasciculus |
| solitary fasciculus | A slender, compact fibre bundle extending longitudinally through the dorsolateral region of the medullary tegmentum, surrounded by the nucleus of the solitary tract, below the obex decussating over the central canal, and descending over some distance into the upper cervical segments of the spinal cord. It is composed of primary sensory fibres that enter with the vagus, glossopharyngeal, and facial nerves, and in part convey information from stretch receptors and chemoreceptors in the walls of the cardiovascular, respiratory, and intestinal tracts; in rostral parts of the tract impulses are generated by the receptor cells of the taste buds in the mucosa of the tongue. Its fibres are distributed to the nucleus of the solitary tract. Synonym: tractus solitarius, fasciculus rotundus, fasciculus solitarius, funiculus solitarius, Gierke's respiratory bundle, Krause's respiratory bundle, round fasciculus, solitary bundle, solitary fasciculus. (05 Mar 2000) |
| subcallosal fasciculus | A bundle of thin nerve fibres running longitudinally beneath the corpus callosum in the angle between the latter and the caudate nucleus; it forms an anterior continuation of the tapetum of the temporal lobe and appears to consist largely of fibres projecting from the cerebral cortex to the caudate nucleus. Synonym: fasciculus subcallosus. (05 Mar 2000) |
| subthalamic fasciculus | Nerve fibres crossing the internal capsule between the subthalamic nucleus and the globus pallidus; this fasciculus contains pallidosubthalamic and subthalamopallidal fibres. (05 Mar 2000) |
| nucleus of cuneate fasciculus | The larger Burdach's nucleus; one of the three nuclei of the posterior column of the spinal cord; located near the dorsal surface of the medulla oblongata at and below the level of the obex, the nucleus receives posterior root fibres corresponding to the sensory innervation of the arm and hand of the same side; together with its medial companion, the gracile nucleus, it is the major source of origin of the medial lemniscus. Synonym: nucleus cuneatus, Burdach's nucleus, nucleus funiculi cuneati, nucleus of cuneate fasciculus. (05 Mar 2000) |
| superior longitudinal fasciculus | Long association fibre bundle lateral to the centrum ovale of the cerebral hemisphere, connecting the frontal, occipital, and temporal lobes; the fibres pass from the frontal lobe through the operculum to the posterior end of the lateral sulcus where many fibres radiate into the occipital lobe and others turn downward and forward around the putamen and pass to anterior portions of the temporal lobe. Synonym: fasciculus longitudinalis superior, arcuate fasciculus. (05 Mar 2000) |
