7.
Regarding the speech centres p458 Lasts
a.
Broca’s area is on the left side in most left handed people T - is on the left side in R handed and MOST L handed
b.
Broca’s area is posterior
F - it is anterior in the inferior frontal gyrus
(wernicke’s is posterior in the superior and middle temporal gyri)
c.
Wernicke’s area controls motor response
F – receptive
d.
Damage to Broca’s area produces motor aphasia
T - (aka expressive) Blitz and Adam reckon this is the better answer
e.
Damage to Wernicke’s area produces expressive aphasia F - receptive
8.
Regarding the medulla oblongata
a.
It is the part of the brainstem between the pons
and spinal cord
T - Midbrain to pons to medulla lasts p 468
b.
Is largely within the middle cranial fossa
F - extends through the foramen magnum to the level of atlas
c.
Is supplied by anterior inferior cerebellar artery
F - Vertebral, basilar, PICA lastsp 475
9.
The dorsal column pathways synapse in the
a.
Thalamus
F
b.
gracile and cuneate nuclei
T - They lie in the medulla. Lasts p485
c.
cerebellum
F
10.
The midbrain
a.
is largely in the middle cranial fossa
F - Most in posterior cranial fossa p469 Lasts
b.
is supplied by the anterior inferior cerebellar artery
F - posterior cerebral and superior cerebellar
c.
lies between pons and upper spinal cord
F - this is the medulla
d.
contains the occulomotor nuclei
T
e.
contains the trigeminal nuclei
F - in the pons
11.
Regarding the lateral ventricles
a.
choroid plexus extends into the canal
T - if they mean it extends into the interventricular foramen (lasts p461)
b.
posterior horn in the temporal lobe
F - Posterior in occipital lobe, anterior in frontal lobe. Inferior temporal lobe
c.
Something about inferior horn
d.
Something about white matter
12.

h.
dural sinuses
F
CSF produced by choroids plexus in lateral, and 3
rd
, and 4
th
ventricles.
Flow: lateral ventricles, through interventricular foramena, to 3
rd
ventricles,
through cerebral aqueduct, to 4
th
ventricles, through median and
lateral apertures, to subarach space
