86. All of the following statementsconcerning the corticospinal tract arecorrect EXCEPT:A. Most of the upper motor neuronshave their cell bodies in the precentralgyrusB. Pyramidal tract axons descendthrough the corona radiataC. Upper motor neurons reach theanterior limb of the internal capsuleD. Pyramidal tract separates intobundles in the midbrainE. Uncrossed pyramidal fibers continueas the ventral corticospinal tract
Most of the neurons from the fasciculus gracilis synapse in the inferior thoraxand enter the spinocerebellar system, whereas most of the neurons fromthe fasciculus cuneatus synapse in the nucleus cuneatus and then continueto the thalamus and cerebrum. Therefore, it can be deduced that most ofthe proprioception from the lower limbs is unconscious and most of theproprioception from the upper limbs is conscious. Explain why this differencein the two sets of limbs is of value.
Melissa had a horrible headache, restricted movement in herright arm, and slight slurring of her speech. After an MRIwas performed, the ER physician suggested that Melissa hadsuffered a CVA (cerebrovascular accident). What structures inthe brain were affected by this incident? What might be thecause of the problem and the expected outcome?
How is it explained that aperson with the spinal cordsectioned at the cervical levelis still able to perform thepatellar reflex?

Shannon felt strange when she awoke one morning. Shecould not hold a pen in her right hand when trying to writean entry in her diary, and her muscles were noticeablyweaker on the right side of her body. Additionally, herhusband noticed that she was slurring her speech, so he tookher to the emergency room. What does the ER physiciansuspect has occurred? Where in the brain might thephysician suspect that abnormal activity or perhaps a lesionis located, and why?
Watch this short video (http://openstaxcollege.org/l/facialnerve) to see an examination of the facial nerve usingsome simple tests. The facial nerve controls the musclesof facial expression. Severe deficits will be obvious inwatching someone use those muscles for normal control.One side of the face might not move like the other side. Butdirected tests, especially for contraction against resistance,require a formal testing of the muscles. The muscles of theupper and lower face need to be tested. The strength testin this video involves the patient squeezing her eyes shutand the examiner trying to pry her eyes open. Why does theexaminer ask her to try a second time?
