All of the following coical areas contribute fibers to the coicospinal tract, EXCEPT?
High-Yield Explanation
Coicospinal and coicobulbar tract neurons are pyramidal shaped and located in layer V of the cerebral coex. About 31% of the coicospinal tract neurons are from the primary motor coex. The premotor coex and supplementary motor coex account for 29% of the coicospinal tract neurons. The other 40% of coicospinal tract neurons originate in the parietal lobe and primary somatosensory area in the postcentral gyrus. The inferior or ventral temporal coex does not contribute fibers to the coicospinal tract.
