16
Q

An important source of dopamine for the motor system can be found in which structure

A

Substantial nigra

17
Q

Unable to adduct right eye where is problem

18
Q

What level of the brainstem is Mickey Mouse

19
Q

Name of important region on midbrain

A

Substantia nigra

20
Q

tumour compressing left cerebral peduncle effects

A

Motor fibres only- motor effects

No sensory effects as sensory fibres ascend directly to thalamus via Mickey Mouse ears

21
Q

At what point do second order neurones of the spinothalamic system decussate and DCML system

A

At the level of entry of first order neurones = spinothalamic

In the medulla = DCML

22
Q

Draw the joint position pathway to cerebral cortex

A

DCML

2nd order in medulla, dorsal column nuclei , then decussate

23
Q

Amaurosis fugax is caused by

A

blockage of central retinal artery

24
Q

which structures do the superior cerebellar arteries supply

25
thalamoperformator arteries are branches of which main artery
posterior cerebral
26
internuclear ophthalmoplegia can be caused by
damage to medial longitudinal fasciculus
27
photoreceptor cells synapse with which retinal type predominantly
bipolar cell
28
homonymous superior quandrantanopia is most commonly seen in lesions to which part of visual pathway
meyer's loop
29
tumour arising from right cavernous sinus invading medially towards optic chiasm consequence
right nasal hemanopia
30
Lateral geniculate nucleus projects to which lobe
occipital- part of thalamus
31
Medial geniculate nucleus projects to
auditory processing centre
32
in which part of the retina are cones common
macula
33
where are there no photo receptors
optic disc
34
what is at peripheral retina
rods
35
transient loss of vision in one eye that resolved after 4 hours likely to be
occlusion to ophthalmic artery = amaurosis fugax
