1. A 30 year old man comes into your office complaining of drooping and not being able to move his lower face. Where is the lesion most likely to be? Cranial nerve VII Substantia nigra Nucleus of cranial nerve VII Cerebral Cortex

2. A 55 year old man enters your office. As he walks in you notice that he is slamming his feet on the ground with each step as hard as he can. When you ask him to close his eyes with his feet together he begins to sway and you have to catch him to keep him from falling. Where is the likely lesion? Spinothalamic tract in the spinal cord Posterior Columns in the spinal cord Trigeminal nucleus in the brain stem Lingula of occipital lobe

3. A 45 year old man is brought into your office by his wife who tells you that he became suddenly confused. You ask the patient how he is feeling and he replies, "Tuesday is a great day to chop the purple lettuce, Doc." What kind of aphasia is the man exhibiting? Broca's aphasia Wernicke's aphasia Global aphasia Conduction aphasia

4. A 20 year old woman complains of knocking over garbage cans while driving. Upon further testing you discover that she has bilateral temporal hemianopsia (loss of temporal vision). Upon further questioning you discover that she has not had a period in 4 months. Where would the lesion that causes these symptoms be located? Anterior pituitary Hypothalamus Posterior pituitary Thalamus

5. In a patient with a tumor on the anterior pituitary that causes amenorrhea, what is the likely hormone that is being produced in excess? Oxytocin Prolactin Vasopressin Follicle stimulating hormone

6. A 70 year old man shuffles into your office complaining of uncontrollable shaking of his extremities. After proper evaluation, you diagnose the patient to be suffering from Parkinson's disease. What chemical substance is lacking in this patient? Fluorouracil Acetylcholine Testosterone Dopamine

7. You are making rounds in the hospital one morning and come across a man who was admitted the night before because of a stroke. Your neurologic evaluation yields loss of pain and temperature to the right side of the face, loss of pain and temperature to the left arm and leg, ataxia (loss of proprioception and balance) on the right side, dysphagia (difficulty swallowing), hoarseness and constant hiccupping. Based on this consultation, what artery was likely occluded during this patient's stroke? Left posterior cerebral artery Right posterior cerebral artery Right posterior inferior cerebellar artery Left posterior inferior cerebellar artery

8. A patient enters your office complaining of weakness in the left leg. The patient has a positive Babinski reflex (up-curling of toes when stroking the lateral foot) and is hyperreflexive. You conclude that these are lower motor neuron findings. Are you correct? Yes No

9. A 65 year old woman presents to you with loss of motor capabilities in her left leg and urinary incontinence. Without any further testing, where would you expect the lesion to be? Right precentral gyrus Left cingulate cortex Left precentral gyrus Right paracentral lobule

10. In a patient that experiences simultaneous leg weakness and urinary incontinence, what artery would likely be occluded if the symptoms were attributable to a stroke? Middle Cerebral Artery Anterior Cerebral Artery Anterior Spinal Artery Hypophyseal Capillary Plexus
