Previous answers to First question is not right
1. Patient deficient in B12 is showing neuropathy. What part of the spinal cord is SPARED?!
A. Dorsal columns
B. Corticospinal tracts
C. Spinocerebellar tracts
D. All are damaged
All can be damged. additionally cerbellum and optic nerves can be involved. Other answers posted already are correct.

Their are two parts to a gag reflex...the AFFERENT limb by CN IX and the EFFERENT limb by CN X. I asked for the efferent limb specifically in the ?.

Correct Answers 10-12:
10. C
11. B
12. C
Sorry the last few werent too much clinical based but Im making up ?s based on my readings from High Yield Neuroanatomy and all this stuff is bolded. Regarding the last one, it is a definition but I wanted people to realize that aphasia is a DOMINANT hemisphere language hemisphere so I asked you about nondominant instead which is dysprosody. On Q10 make sure you realize that Broca's is more specifically INFERIOR frontal (whereas Wernicke's is SUPERIOR temporal).
That's all for now...hope you enjoyed.

Is there any mnemonics to memerize the dif presentation for the lession of Broca's and Wernicke's?

Think of Broca's as BROKEN SPEECH for example "Me...Tarzan...you...Jane" When you say it out loud you realize it is GOOD comprehension but NONFLUENT. For Wernicke's think of WORDY as in someone saying a bunch of words all in a row real fast, like a speed talker! So if try listening to them you will see that they are speaking FLUENT but POOR comprehension (because you cannot understand them). Both of these also have poor repetition.
Their are more types of aphasia(although not as HY) and High Yield NA has a cool square diagram thingy that is easy to memorize.
