Definition of crus cerebri in English: crus cerebrinounPlural crura cerebriˈsɛrɪbrʌɪˈkerəˌbrē Anatomy Either of two symmetrical tracts of nerve fibres at the base of the midbrain, linking the pons and the cerebral hemispheres. Example sentencesExamples - This intersecting and mingling is characteristic of association bundles, and contrasts with the orderly formation of projection tracts found in the internal capsule and crus cerebri.
- Descending fibers course through the massive cerebral peduncles (crura cerebri), the most ventral parts of the midbrain (mesencephalon).
- Lateral pressure on the midbrain can, however, compress the opposite crus cerebri against the free edge of the tentorium, forming an indentation in the crus known as Kernohan's notch.
- The DWI-trace maps and the ADC-maps were analyzed in 10 regions of interest bilaterally: centrum semiovale, ventral, occipital and temporal white matter, dorsal limb of internal capsule, globus pallidus, thalamus, crus cerebri, pons and white and grey matter of cerebellum.
- The Posterior Perforated Space corresponds to a whitish-grey substance, placed between the corpora albicantia in front, the pons Varolii behind, and the crura cerebri on either side.
Origin Early 18th century: from Latin, literally 'leg of the brain'.
