Sessions 1-4 Review Flashcards
Hippocampus is found in which lobe of the brain
temporal lobe
Describe the cranial nerves emerging from the ponto-medullary junction
Abducens = ventrally
Facial = laterally
Superior colliculus is part of which structure
Midbrain
Which region is represented most laterally in the primary motor cortex
The face
Describe Homunculus
Damage to the temporal lobe usually presents with
Recognition deficits
From which structure is the cerebellum embryonically developed
Metencephalon (superior division of the rhombencephalon)
Which functional division is responsible for balance
Vestibulocerebellum
The colliculi of the midbrain are separated by which structure
Cruciform sulcus
The interpeduncular fossa separates which two structures
Cerebral peduncles
The raphe nuclei produce which neurotransmitter
Serotonin
A tumour at the level of the inter ventricular foramen might lead to dilatation of what
Lateral ventricles
Which part of the brainstem lies at the level of the tentorium cerebelli
Midbrain (tentorial notch)
Bridging veins traverse which space
Subdural
In the midbrain, which large white matter structures connect the cerebral hemispheres to the brainstem
Crus cerebri
An important source of dopamine for the motor system can be found in which structure
Substantial nigra
Unable to adduct right eye where is problem
Abducens
What level of the brainstem is Mickey Mouse
Midbrain
Name of important region on midbrain
Substantia nigra
tumour compressing left cerebral peduncle effects
Motor fibres only- motor effects
No sensory effects as sensory fibres ascend directly to thalamus via Mickey Mouse ears
At what point do second order neurones of the spinothalamic system decussate and DCML system
At the level of entry of first order neurones = spinothalamic
In the medulla = DCML
Draw the joint position pathway to cerebral cortex
DCML
2nd order in medulla, dorsal column nuclei , then decussate
Amaurosis fugax is caused by
blockage of central retinal artery
which structures do the superior cerebellar arteries supply
midbrain
thalamoperformator arteries are branches of which main artery
posterior cerebral
internuclear ophthalmoplegia can be caused by
damage to medial longitudinal fasciculus
photoreceptor cells synapse with which retinal type predominantly
bipolar cell
homonymous superior quandrantanopia is most commonly seen in lesions to which part of visual pathway
meyer’s loop
tumour arising from right cavernous sinus invading medially towards optic chiasm consequence
right nasal hemanopia
Lateral geniculate nucleus projects to which lobe
occipital- part of thalamus
Medial geniculate nucleus projects to
auditory processing centre
in which part of the retina are cones common
macula
where are there no photo receptors
optic disc
what is at peripheral retina
rods
transient loss of vision in one eye that resolved after 4 hours likely to be
occlusion to ophthalmic artery = amaurosis fugax
