| paracentral artery | <anatomy, artery> The third branch of the pericallosal artery supplying the cerebral cortex of the paracentral lobule and both sides of the medial part of the central sulcus. Synonym: arteria paracentralis. (05 Mar 2000) |
| paracentral fissure | A curved fissure (sulcus) on the medial surface of the cerebral hemisphere, bounding the paracentral gyrus and separating it from the precuneus and the cingulate gyrus. (05 Mar 2000) |
| paracentral lobule | A division of the medial aspect of the cerebral cortex, lying above the singulate sulcus and bounded by the precentral sulcus in front and the marginal part of the cingulate sulcus behind. Synonym: lobulus paracentralis. (05 Mar 2000) |
| paracentral nucleus of thalamus | One of the intralaminar nuclei of the thalamus, medial to the central lateral nucleus. Synonym: nucleus paracentralis thalami. (05 Mar 2000) |
