posterior spinocerebellar tract

(redirected from Flechsig tract)

pos·te·ri·or spi·no·cer·e·bel·lar tract

[TA]
a compact bundle of heavily myelinated, thick fibers at the periphery of the posterior half of the lateral funiculus of the spinal cord, originating in the ipsilateral thoracic nucleus (column of Clarke) and entering the cerebellum by way of the inferior cerebellar peduncle. Terminals end as mossy fibers in the granular layer of the cortex of the cerebellar vermis and, via collaterals, in the cerebellar nuclei. The bundle conveys largely proprioceptive information originating from the annulospiral nerve endings surrounding muscle spindles and from Golgi tendon organs.

(pos-tēr'ē-ŏr spī'nō-ser'ĕ-bel'ăr trakt) [TA]
A compact bundle of heavily myelinated, thick fibers at the periphery of the dorsal half of the lateral funiculus of the spinal cord, originating in the ipsilateral thoracic nucleus (column of Clarke) and ascending by way of the inferior cerebellar peduncle. Terminals end as mossy fibers in the granular layer of the cortex of the cerebellar vermis. The bundle conveys largely proprioceptive information originating from the anulospiral nerve endings surrounding muscle spindles and from Golgi tendon organs.

Flechsig,

Paul E., German neurologist, 1847-1929.
Flechsig areas - three divisions (anterior, lateral, posterior) of each lateral half of the medulla as seen on transverse section, marked off by the root fibers of the hypoglossal and vagus nerves.
Flechsig fasciculi - fasciculus anterior proprius and fasciculus lateralis proprius. Synonym(s): Flechsig ground bundles

oval area of Flechsig
semilunar nucleus of Flechsig - the small ventral region of the ventral posteromedial nucleus of thalamus in which the fibers of the gustatory lemniscus and secondary trigeminal tracts terminate. Synonym(s): arcuate nucleus of thalamus
