final review pics Flashcards


lesion to the optic nerve
retinal lesion
lesion to the nasal fibers crossing over
lesion where the optic nerve comes into the chiasm
- affecting both central and temporal fibers
lesion to the tract, meyer’s loop or lateral geniculate and these are fibers after crossing over
- pie in the sky
tract lesion leading to complete hemiopoa
lesion to the occipital fibers coming from right next to each other.
visual field deficit is superior and temporal and most likely it is a retinal lession that is inferior and nasal
visual field deficit is inferior thus lesion must be superior. lesion is preventing ganglion cell axons from entering optic nerve
loss of central vision leading to a relative afferent pupillary defect
imaging shows optic nerve inflammation but upon examination retina appears normal. loss of central vision.
temproal field is missing thus probably this a lesion to the chiasm. information from temporal visual field enters nasal retina and must cross in the chiasm
this is a pituitary adenoma that is putting pressure on the chiasm leading to a bi-temporal hemianopia (temporal fields missing
lesion to the optic tract leading to a field defect in both eyes. a nasal on right and temporal on left
demyelinating plaque that is affecting the optic tract
damage to meyer’s loop in temporal fibers
- temporal field vision is not identical
this shows damage to meyer’s loop in temporal lobe usually caused by a tumor or stroke
loss of fibers after crossing over leading to side one eye losing vision on opposite side
infarct in MCA territory leading to all loss of fibers losing vision on opposite side
occipital lobe lesion. alsmost superimposable field defects. left occipital lobe causing right sided visual field defect.
AVM malformation in left occipital lobe causing right sided visual field defect
motor cortex on the left; layers three and five are the pyramidal levels
Number 7. Left homonymous hemianopia with macular sparing
A. Neurons in the lower part of the motor strip give rise to the corticobulbar tract
B. neurons in this region will give rise to axons of the corticospinal tract that will control the muscles of the hand
C. Nerons in this region will receive input from somatosensory pathways from the hand
D. Neurons in this region will receive somatosensory input from the face
E. this is the inferior parietal lobe
X. receives information from?
E. Fornix- part of the Papez circuit
X. receives information from left visual fields in both eyes
Y. Thalamus
Z. anterior lobe of the vermis
- Which controls the autonomu system?
- which is for fear conditioning?
- structure that contains cell bodies that send their axons to VA/VL of the thalamus
- what is X?
- What is Y?
- E; the hypothalamus
- D; amygdala
- C; globus pallidus is the output nucleus of the basal ganglia. receives information from the caudate and putamen and projects to the thalamus
- cingulate gyrus; receives input from the anterior nucleus of the thalamus
- Fornix; originate in the hippocampus
- which is the caudate nucleus
- which is the putamen?
- Thalamus?
- What is X
- What is Y
- D; adjacent to the lateral ventricle
- A; lies lateral to the internal capsule
- C; surrounds the third ventricle
- hippocampal formation; essential for declarative memory
- lateral geniculate nucleus; receives input from ganglion cells of the retina and then projects to primary visual cortex
