40
What nerve innervates most muscle of the soft palate?
CNX - vagus
41
True or False: the uvula of the soft palate deviates to the R = lesion of the R vagus nerve
since the muscles on the lesioned half do not work, elevated soft palate on the L side pulls uvula towards the left = uvula deflects to the unaffected side; therefore right deviation of uvula = left vagus nerve lesion
The correct answer is 'False'.
42
True or False: the tip of protruded tongue deviates to the R = lesion of the R hypoglossal nerve
muscles on the healthy side push the tongue forward while the lesioned half 'wrinkles' and does not move; so tongue deviates towards the side of lesion (this is opposite to the uvula scenario); do not memorize - just try to understand and you always can work it out
The correct answer is 'True'.
