1

Three ligaments which need to be punctured in order to access the CSF in a lumbar puncture

Supraspinous
Interspinous
Ligamentum flavum

2

First palpable vertebra in most people

C7 (vertebra prominens)

3

Level of termination of the spinal cord

L2- conus medullaris

4

Primary sensory cortex

Post-central gyrus

5

Two main sensory pathways

Dorsal columns (fine touch, temperature, proprioception)
Spinothalamic tracts (pain, temperature and crude touch)

6

Decussation/synapse of the sensory pathways

DC- ascends ipsilaterally, crosses at medulla
ST- crosses at level of entry, ascends contralaterally

7

Primary motor cortex is located...

Pre-central gyrus

8

Major motor pathway

Corticospinal tracts (lateral and anterior)

9

Decussation of the CST

Lateral- at the base of the pyramids within the medulla
Anterior-level of entry

10

Where is the dural venous sinus located?

In between the periosteal and meningeal layers of the dura mater

11

Describe the blood supply to the brain
a) posterior
b) anterior

a) the vertebral arteries combining to form the basilar;
b) the internal carotids

12

Where is Broca's area located? What do lesions here result in?

Frontal lobe, expressive aphasia

13

Where is Wernicke's area located? What do lesions here cause?

Temporal lobe;receptive dysphasia

14

The optic tracts carry information about what?

The contralateral visual field

15

Area of the brain responsible for voluntary non-tracking movements of the eye

Frontal eye fields

16

Brain nuclei which direct the consensual pupillary light reflex?

pretectal and edinger-westphal nuclei

17

The visual cortex is locatedin...

The occipital lobe

18

Abducens

19

Cranial nerves which pass through the internal acoustic meatus

Facial nerve
Vestibulocochlear

20

Cranial nerves which pass through the jugular foramen

Glossopharyngeal
Vagus
Accessory

21

V2 and V3 of trigeminal nerve pass through which foraminae?

V2- foramen rotundum
V3- foramen ovale

22

The a) olfactory and b) optic nerves pass through which foraminae?

a) cribriform plate of ethmoid bone
b) optic canal of sphenoid
