Cerebral peduncle

Brain: Cerebral peduncle Superficial dissection of brain-stem. Ventral view. ("Cerebral peduncle" visible in red at center-right.) Section through superior colliculus showing path of oculomotor nerve. (Crus cerebri labeled at lower left.) Latin pedunculus cerebri Gray's subject #188 800 Part of Components Artery Vein = Vein {{{Vein}}} BrainInfo/UW hier-478 MeSH A08. Mainly, the three common areas that give rise to the cerebral peduncles are the cortex, the spinal cord and the cerebellum.[1] The cerebral peduncle, by most classifications, is everything in the mesencephalon except the tectum.[citazione necessaria] The region includes the midbrain tegmentum, crus cerebri and pretectum. By this definition, the cerebral peduncles are also known as the basis pedunculi, while the large ventral bundle of efferent fibers is referred to as the crus cerebri or the pes pedunculi. There are numerous nerve tracts located within this section of the brainstem. Of note, in the cerebral peduncular loop fibers from motor areas of the brain project to the cerebral peduncle and then project to various thalamic nuclei. Important fibers running through the cerebral peduncles include the corticospinal tract and the corticobulbar tract, tra gli altri. This area contains many nerve tracts conveying motor information to and from the brain to the rest of the body.
