loss of vibratory sense perception from L LE
If in an anesthetized animal you destroy the nucleus solitaries bilaterally, the lesion would be in the _____, and the _____ would be lost.
Medulla and the ability to taste
A person who could not perform rapidly alternating movements w/ L hand and who always leaned toward L for balance probably has a lesion in the:

A neurological exam revealed that the 70 year old woman's R hand would tremble when she put on her glasses. Her speech was also slurred and she could not touch her nose w/ her index finger. Based on the info, where might a lesion exist?
cerebellum
If the L corticobulbar tract were lesioned, which of the following clinical situation is possible?
spastic paralysis of mm of facial expression on R lower side of face
A 56 yr old man was taken to the ER. The next day, a neurological exam showed that Broca's aphasia was evident, that there was spastic paralysis of the lower facial mm on the R side and that reflexes of R UE displayed hyperreflexia. Where might the problem lie?
frontal cortex on left
It was noted that a pt had lost all vision on the R visual field which indicated that the ____ was damaged, as well as spastic paralysis of the R half of the tongue mm, which indicated ___ was damaged.
L optic tract/L internal capsule
If a person's L eyeball deviated medially, and there was loss of pain and temperature perception from R side of face, where might the lesion be?
L side of pons
At the conclusion of a comprehensive eye exam, the optometrist told the pt she has lost vision in her L visual field, this would be due to:
R optic tract
If a person could no longer produce saliva from R parotid gland, had flaccid paralysis of tongue mm on R and loss of pain and temp sensations from L side of body, one might suspect lesion in the:
R side of medulla
If the facial motor nucleus of the R facial cranial N were completely destroyed, which of the following best describes the clinical significance?
flaccid paralysis of all mm of facial expression on R side
Pt told neurologist that he could not seem to focus w/ eyes and that he had trouble chewing food. The exam revealed his mm of mastication were weak and strabismus was present. Based on this info, the lesion was probably in the:
tegmentum of pons
After a thorough neurological exam, the neurologist presents the following info to students:
pt had difficulty touching tip of R index finger to nose
had a tendency to lean to the R when walking
had a fine tremor in her R hand when she tried to pick up a pencil
noted that all mm of facial expression on R side were beginning to weaken
CAT scan revealed tumor mass
Based on this info, where would you expect to find the tumor?
R cerebellar hemisphere w/ involvement of R side of pons
If SC were completely severed at L1 level, can pt still have DTRs?
yes
A pt came to the hospital w/ the following problems:
1. transitory periods of consciousness
2. facial mm on lower half of R side of face exhibited spastic paralysis
3. tongue protrude to R when extended
4. no involvement of eye mm, mm of pharynx or larynx
5. unusual behavior
Based on this info, where was the area of involvement?
Neuro exam revealed that R iris couldn't constrict and R eye couldn't get coordinated (strabismus) w/ L eye. No indication of UMN involved. Where is lesion?
R midbrain
Malignant neoplasm destroyed R crus cerebri, which would be clinical result?
