1

Which cranial fossa does the brainstem lie in

Posterior cranial fossa

2

Embryologically which 2 vesicles of the neural tube give rise to the brainstem

Mesencephalon and Rhombencephalon

3

Which cranial nerves can you see emerging from pontomedullary junction

Abducen VI
Vagus V
Facial CN VII
Vestibulochlear CN VIII

4

What Cavities of the ventricular system lie within the brain stem

IV Trochlear

5

The trochlear intracranial course makes it vulnerable to injury by increased intracranial pressure. What would be the consequence of this nerve being injured

Weakness or paralysis of the superior oblique

6

What do the pyramids contain

Efferent corticospinal fibres for muscle movement

7

What produces the decussation of the pyramids

Corticospinal fibres cross the midline to form these

8

What forms the olive

Inferior olivary nucleus lies within the olive

9

Which part of the medulla is the open part

Superior

10

Which part of the medulla is the closed part

Inferior (caudal)

11

Through which foramen does the medulla pass to become the spinal cord

Foramen magnum

12

On the surface of the peons where does the trigeminal nerve originate

Lateral aspect

13

The middle cerebral peduncle is made up of what

Centripetal fibres

14

Which part of the brain lies superior to the midbrain

Diencephalon

15

Which part of the brain lies immediately inferior to the midbrain

Pons

16

The cerebral peduncles, what kind of fibres make up them and what are they destined for

Large ascending (sensory) and descending (motor) nerve tracts that run to and from the cerebrum from the pons

17

Which parts of the brain do the diencephalon lie between

Brain stem and cerebral hemisphere

18

What are the surface projections visible on the surface of the hypothalamus called

Maxillary body

19

What is the name given to the midline structure connecting the 2 cerebellar hemispheres

Corpus callosum

20

To what part(s) of the brain is the vermis anatomically connected to by peduncles

Superior peduncle- midbrain
Middle peduncle- pons
Inferior peduncle- medulla

21

What is the name of the ventricular space that lies immediately anterior to the cerebellum

Fourth ventricle

22

What cranial fossa is the cerebellum in contact with

Posterior cranial fossa

23

What foramen in the skull does the cerebellum sit above

Foramen Magnum

24

What is the name of the part of the cerebellum that sits atop the Forman magnum

Cerebellar tonsils

25

When there is a drop intracranial pressure what can happen

The tonsils may herniate through the foramen magnum

26

What is the name given to the large fissure separating the 2 cerebral hemispheres

Lateral ventricle

27

What type of nerve fibres are most likely to be carried in the corpus callosum

Commisural

28

What lobes contain the primary motor cortex

Pre-central gyrus

29

What lobes contain the primary visual cortex

Occipital (visual cortex)

30

What lobe contains the auditory complex

Superior temoral gyrus
