Proposed merge with Decussation of pyramids

Would be better presented in a single place, would add to clarity & quality, benefit readers, & reduce needless fragmentation LT910001 (talk) 02:33, 25 January 2014 (UTC)  Done[reply]

Corticobulbar Tracts

I do not have access to the Nieuwenhuys et al. text referenced, but Haines' text (Fundamental Neuroscience) does not mention the presence of corticobulbar tracts in the pyramids. Purves et al.'s text (Neuroscience) goes further, and indicates that corticobulbar axons exit the bundle superior to the pyramids to terminate in various regions of the medulla. Furthermore, it is difficult to see how corticobulbar axons could be present in the pyramids, because the pyramids lie at the extreme caudal end of the medulla, just before it transitions to being the spinal cord. The point is important because without the corticobulbar tracts, the statement under Clinical Significance that attributes difficulty swallowing and difficulty speaking to pyramidal damage during whiplash does not make logical sense. Whiplash could cause swallowing and speaking difficulties by damaging other structures present in the medulla. Does any one have access to the Nieuwenhuys et al. text to check the reference, and if the statement is there, to check Nieuwenhuys et al.'s references? I would suggest that the article be rephrased to omit reference to the corticobulbar tracts and to swallowing and speaking.
