P1 EXAM 16. This is called the ‘where’ stream. A. FRONTAL LOBE A. Dorsal B. TEMPORAL LOBE C. OCCIPITAL LOBE 17. This stream is for spatial awareness D. PARIETAL LOBE A. Dorsal E. HYPOTHALAMUS F. PITUITARY GLAND 18. This is for recognition and discrimination of G. BRAINSTEM visual shapes and objects. H. CEREBELLUM B. Ventral I. HIPPOCAMPUS 19. These are Extra striate Visual Areas. 1. This is in charge of your thought processes. C. Both A. Frontal 20. This is also called the ‘What’ Stream. 2. This receives and identify sensory information. B. Ventral D. Parietal I. Layer 1 3. It controls the release of most hormones. II. Layer 2 F. Pituitary Gland III. Layer 3 IV. Layer 4 4. This is in charge of your body temperature, V. Layer 5 hunger, and thirst. VI. Layer 6 E. Hypothalamus A. I and II 5. This lets you perceive things like touch, taste B. III, IV, V, and VI and pain. C. I, VI, and VI D. Parietal D. II, III, and V E. I only 6. This is in charge of your Auditory process. B. Temporal 21. Information from the contralateral eye goes to this layer. 7. It controls your breathing, heartbeat, facial C. I, VI, and VI expressions, etc. G. Brainstem 22. This layer is closest to the hilum. E. I only 8. This interprets visual images. C. Occipital 23. These layers receive signals that travel by the magnocellular pathway. 9. It helps you coordinate when you move. A. I and II H. Cerebellum 24. Information from the ipsilateral eye goes to 10. It helps you make long term memories. these layers. I. Hippocampus D. II, III, and V 11. This is where voluntary motor ability starts. 25. The signals received by these layers travel by A. Frontal the parvocellular pathway. B. III, IV, V, and VI 12. This lobe is in charge for your sensory and motor perception. I. Argyll-Robertson Pupil D. Parietal II. Adie’s Tonic Pupil III. Marcus Gunn Pupil 13. This is where decision making, initiation of IV. Amaurotic Pupil plans and termination of actions takes place. A. Frontal A. I only B. IV only 14. This lobe is in charge of your vision. C. I and II C. Occipital D. III and IV E. None of the Choices 15. This lobe is for language comprehension. B. Temporal 26. It is caused by an incomplete optic nerve lesions or a severe retinal disease. I. Dorsal Stream II. Ventral Stream E (III only RAPD/Marcus Gunn Pupil) A. I 27. Caused by denervation of the postganglionic B. II supply of the sphincter pupillae and ciliary C. Both I and II muscle of unknown etiology. D. None E (II only Adie’s Tonic Pupil) 28. Bilateral, miotic pupil with irregular margins and 46. Large cells pass to through this pathway. are symmetrical. Magnocellular A (Argyll) 47. This is in charge for the movement perception. 29. Caused by a complete optic nerve or retinal Magnocellular lesion leading to total blindness on the affected side. 48. Lesion this part will result to congruous B (Amaurotic) homonymous hemianopia with macular sparing. Visual Cortex 30. Absence of direct light reflex on the affected side and absence of the consensual light reflex 49. Lesions on this part will give rise to incongruous on the normal side. homonymous hemianopia. B (Amaurotic) LGN 31. Afferent Pupillary Pathway Defects. 50. Bitemporal and Binasal hemianopia could be D III and IV (RAPD & TAPD) seen if the patient has a lesion on this part. Optic Chiasma 32. These pupillary pathway defects are non- reactive to light reflex but reacts to near reflex. 51. It is also known as the 'what' stream. C I and II (Argyll and Adie) Ventral 33. Efferent Pupillary Pathway Defects. 52. Pie on the sky type of defect could be seen if C I and II (Argyll and Adie) this area has a lesion. Optic Radiations 34. Also known as TAPD. B (Amaurotic) 53. Baums and Meyers loop are both alternative name of this. 35. Also known as RAPD. Optic Radiations E (III only) 54. These fibers pass above and below as arcuate IDENTIFICATION fibers. Temporal Fibers 36. Facial processing is in this pathway. Parvocellular 55. Lesions of this area will lead to congruous homonymous macular defect. 37. Recognition and discrimination of visual shapes Visual Cortex and objects. Ventral ENUMERATION 38. Spatial awareness. 56. Triad of Horner's Syndrome Dorsal Miosis Ptosis 39. Also known as the 'where' stream. Anhidrosis Dorsal 57. Two major muscles responsible for pupil 40. It is only in this part of the visual pathway that reactions impulses from corresponding points of two Dilator pupillae muscle retinal meet. Sphincter pupillae muscle Visual Cortex 58. Three types of Reflexes 41. Information from the contralateral eye goes to Light reflex what layer? Near reflex Layers 1,4,6 Darkness reflex 42. These layers of LGN receive signals that travel 59. Synkinesis of near reflex by the parvocellular pathway. Accommodation Layers 3-6 Convergence Miosis 43. Flattened structure above pituitary fossa. Optic chiasma 60.
