|---|---|
| complete the diagram by which the major motor centers influence the motor cortices | wide areas of cerebral cortex, substantia nigra, thalamic nuclei (all 3) to neostratium to paleostratium to ventral lateral nuclei and ventral anterior nuclei (also going to VLN and VAN is globus emboliform and dentate) VLN to Areas 4 & 6 to Lower Motor N |
| a person has a vascular lesion which gives signs and symptoms of both basal nuclear and and pontocerebellar dysfunctions. give the most likely location of the lesion | anterior limb of internal capsule |
| a person has vascular lesion which interrupts the left temporal loop fibers. Darken the expected blind visual areas | darken upper right quarter of both circles |
| what motor deficits is likely with an interruption of fibers in the genu of the left internal capsule? | Deviation of protruded tongue; inability to smile on the right |
| name the motor condition described: characterized by truncal ataxia and nystagmus | flocculonodular syndrome |
| name the motor condition described: violent involuntary flailing movements resulting from a lesion in the contralateral subthalamic nuclei | hemiballismus |
| name the motor condition described: hyperkinetic autosomal dominant genetic disease characterized by widespread destruction of the basal nuclei and the cerebrum | huntington's chorea |
| into which of the two categories of basal nuclear deficits does parkinson's belong? | hypokenisia; hypertonia |
| A person presents with an inability to smile on the L side. If this is accompanied by an inability to close the L eye tightly. Which one is most likely the site of the lesion | L facial nerve |
| receptive aphasia may result from an occlusion in the ______ artery (include side) | L middle cerebral a. |
| A person presents with an inability to smile on the L side. If the ability to close the L eye is normal. other deficits | L tongue, L hand, pain L forehead (NOT L leg, NOT L mastication) |
| A person presents with an inability to smile on the L side. If the ability to close the L eye is normal. general sensory deficit | Left face pain deficit, receptive aphasia |
| A person presents with an inability to smile on the L side. If this is accompanied by an inability to close the L eye tightly. Which general sensory deficits would be expected: R face, L face, R leg, L leg, none of the above | none of the above |
| name the motor condition described: hypokinetic disease characterized by slow movements, increased muscle tone, loss of facial expression, and pill-rolling tremors | Parkinson's disease |
| A person presents with an inability to smile on the L side. If the ability to close the L eye is normal. Where is the likely occlusion | R lateral cerebral cortex |
| a person complains of dizziness and deafness in the right ear. where is the problem | Right vestibulocochlear nerve |
| A person presents with an inability to smile on the L side. If this is accompanied by an inability to close the L eye tightly. Which other deficits are likely: R mastication, salivation, L tongue, taste, Horner's syndrome, receptive aphasia | salivation, taste |
| Parkinson's disease results from pathology in ______ | substantia nigra |
| name the motor condition described: may develop following rheumatic fever | syndenham's chorea |
| name the motor condition described: involuntary movements of the tongue and face induces by anti-psychotic drugs | tardive dyskinesia |
| what may result with disturbances in the vestibular system | truncal ataxia; nystagmus |
| A person develops a dramatic increase in appetite with weight gain and changes in behavior marked by expressions of rage. wht is the likely site of a lesion? | ?Med \ /, limbic |
| Dislocation of the uncus may occlude the ____artery | Anterior Cerebral Artery |
| A person suffers hearing loss due to a vascular lesion. If this also includes deficits in general sensation to the head and body, which artery is affected | posterior inferior cerebellar artery |
| due to a lesion in the contralateral subthalamic nucleus | hemiballismus |
