This is a real-world medical entrance exam question, please give the true answer based on the question and selection. Topic name: None, Subject name: Anatomy
All of the following coical areas contribute fibers to the coicospinal tract, EXCEPT? 
Select and explain. 
A. Primary motor coex (precentral gyrus), B. Premotor coex, C. Inferior temporal coex, D. Primary somatosensory coex (postcentral gyrus)
C: Inferior temporal coex
Answer: C: Inferior temporal coex 
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.
