| Question | Answer |
|---|---|
| A person experiences loss of all general sensation in the L leg and loss of voluntary motor control in the L leg. Which artery was likely occluded? | right anterior cerebral artery |
| the primary general sensory area for the foot is supplied by the _____ artery | anterior cerebral artery |
| An occlusion of which cerebral artery would result in loss of all general sensation in the lower extremity | anterior cerebral artery |
| A person presents with abnormal ocular movements and complaints of visual deficits which have developed over the last 2 days. You suspect a slow bleeding aneurysm located _______ | Opthalamic artery or any other artery of circle of wilis (b/c sits in optic chiasm) |
| A person is unable to interpret the meaning of spoken language. an occlusion of which artery would cause this deficit | middle cerebral artery |
| Consider an occlusion of the left middle cerebral artery. Voluntary motor deficits are expeced in the: L mm of mastication, R mm of mastication, R smile, L smile, R eye closure, L eye closure, R leg, L leg. | ?R smile, R eye closure |
| Consider an occlusion of the left middle cerebral artery. Pain deficits are expected in the: R upper face, L upper face, R lower face, L lower face, R leg, L leg | ?R upper face, R lower face |
| Consider an occlusion of the left middle cerebral artery. Are language deficits expected? | yes, because the left middle cerebral aa. supplies the left frontal, parietal, and temporal lobe of motor speech (Area 44,45) and sensory language (Area 22, 41,42) |
| Consider an occlusion of the middle cerebral artery supplying the left lateral temporal and frontal lobes would likely result in deficits in ____ | motor speech (Area 44,45) and sensory language (Area 22, 41,42); prefrontal (Area 9, 10, 11); motor (Area 4,6) |
| the anterior choroidal artery is prone to thrombosis. Which structure does it supply that are especially sensitive to ischemia? | Choroid Plexus or Hippocampus or Globus Pallidus |
| the anterior choroidal artery is notable because it is often occluded and several structures it supplies are especially sensitive to ischemia. what are those two structures? | hippocampus; globus pallidus |
| Hypertension is believed to be a significant contributing factor in ____hemorrhages. | intracerebral |
| Name the artery supplyinig each of the following in the open medulla: Inferior cerbellar peduncle. Answer options: anterior spinal, posterior inferior cerebellar, posterior spinal, none of the above | posterior inferior cerebellar |
| the posterior lateral open medulla receives blood supply from the ________ | posterior inferior cerebellar |
| which blood vessel supplies the posterior lateral aspect of the open medulla | posterior inferior cerebellar artery (PICA) |
| A person has an occlusion of the R posterior inferior cerebellar artery. Explain each of the observations listed below.Loss of pain of the right face. | ?primary neurons carrying pain from the face, descend to the spinotrigeminal nucleus located mid pons to C2 where pica occludes before it can cross over to left side |
| A person has an occlusion of the R posterior inferior cerebellar artery. Explain each of the observations listed below.Loss of pain of the left body. | ?neospinothalamic tract crossed over in spinal cord |
| A person has an occlusion of the R posterior inferior cerebellar artery. Explain each of the observations listed below. normal discriminating touch on the face. | ?b/c pica is at closed medulla level and chief sensory nucleus is above at mid pons |
| Name the arteries that supply the darkened areas (pictures of cross section of medulla from the superior view, ie. with 4th ventricle) | ?anterior spinal; PICA |
| in general, below mid cervical level, the _________ artery supplies blood to the anterior spinal artery | anterior radicular artery |
| Consider an occlusion of the anterior spinal artery at the T3 spinal cord. What areas will have a deficit in pain? What areas will have a deficit in discriminating touch? R arm, L arm, R leg, L leg, None | pain: R leg, L leg; dicscriminating touch: None |
| Name the artery supplyinig each of the following in the open medulla: pyramid. Answer options: anterior spinal, posterior inferior cerebellar, posterior spinal, none of the above | anterior spinal |
| Name the artery supplyinig each of the following in the open medulla: medial lemniscus. Answer options: anterior spinal, posterior inferior cerebellar, posterior spinal, none of the above | anterior spinal |
| Consider an occlusion of the anterior spinal artery at the T10 spinal cord. What areas will have a deficit in pain? What areas will have a deficit in discriminating touch? R arm, L arm, R leg, L leg, None | pain: R leg, L leg; dicscriminating touch: None |
| Consider an occlusion of Anterior spinal artery supplying the C4 spinal cord. Pain and DT deficits? R arm, L arm, R leg, L leg, R cheek, L cheek, No deficit. | Pain: Both arms and legs, DT: No deficit |
| below the cervical cord, the anterior spinal artery receives blood from the ________ | Anterior radicular artery |
| Consider an occlusion of Anterior spinal artery supplying the C4 spinal cord. What deficits are expected in the R arm and L leg? Pain, temperature, crude touch and pressure; discriminating touch; proprioception to the cerebellum; no sensory deficit is ex | R arm: pain, temperature, crude touch and pressure. L leg: pain, temperature, crude toch and pressure |
| The pyramids are supplied by the ________ artery. | Anterior spinal |
| What deficits would likely result from an occlusion of the left posterior spinal artery supplying L2-4? explain your answer | none- efficient anastomosis between left and right posterior spinal arteries at that level |
| nuclei gracilis and cuneatus are supplied by the _________ artery | posterior spinal artery |
| Consider an occlusion of the left posterior spinal artery supplying the T10 spinal cord. Deficits in which modalities are expected. Explain your answer. | None, Anastamosis |
| Consider an occlusion of the left posterior spinal artery supplying the left T12 spinal cord. Deficits in which modalities are expected. Explain your answer. | None, Anastamosis |
| what is the most common site of congenital aneurysm | circle of willis |
| the anterior radicular arteries branch off of the _______ arteries | segmental |
| an expanding aortic aneurysm may result in deficits due to occlusion of the _______- arteries | segmental |
| name the type of hemorrhage described, results from tearing a meningeal artery | Epidural |
| name the type of hemorrhage described, would result from tearing the superior cervical vein as it empties in the superior sagittal sinus | subdural |
| The subdural hemorrhage most commonly results from a blow to the front or back of the head which results in tearing of a ________where it enters the | superior cerebral vein, superior sagittal sinus |
