25
Q

How many pairs of spinal nerves are there ?

A

31

26
Q

At what level doe the internal and external carotid arteries arise ?

A

C4

27
Q

What is the carotid sinus and where is it found ?

A

The terminal part of the common carotid and it monitors blood flow to the head and brain

28
Q

what cranial nerves are associated with the carotid sinus ?

A

Sensory nerves from the carotid sinus run in the glossopharyngeal and vagus nevre.

29
Q

What is the carotid body and where is it found ?

A

An area of the terminal part of the common carotid and it contains chemo receptors which sense low oxygen levels

30
Q

Which cranial nerve/s is associated with the carotid body ?

A

sensory nerves from the carotid body run in the Glossopharyngeal

31
Q

What are the sympathetic motor nerves and where are they found ?

A

These nerves form a plexus around the internal carotid artery and enter the skull with the artery through the carotid canal and follow the the main branches of the internal carotid artery

32
Q

Where does the superior opthalmic vein drain into ?

A

The cavernous sinus

33
Q

What are emissary veins?

A

Veins that connect the cranial venous sinuses with the diploe of the skull which is continuous with the veins of the superficial fascia overlying the scalp

34
Q

Where do the inferior petrosal sinus lie ?

A

Lie at the base of the brain and are connected to each other. The run alongside the petrous part of the temporal bone also.

35
Q

What is the Pterion ?

A

It is an area of the skull where the frontal, parietal, temporal and sphenoid join just behind the temple

36
Q

which important artery is found just below the pterion ?

A

Middle miningeal artery

37
Q

Which artery is the MMA a branch of ? and which skull foramen does it use to enter the brain from this artery ?

A

External carotid -> Maxillary artery -> MMA and it enters through foramen spinosum

38
Q

If the MMA is damaged what can this cause ?

A

Extradural haematoma

39
Q

Which veins drain int the cavernous sinus ?

A

the superior and inferior opthalmic veins through the superior orbital fissure

40
Q

Which nerves run through the cavernous sinus ?

A

III, IV, V (1&2) & VI

41
Q

How does the cavernous sinus drain ?

A

Drains into the petrosal sinuses and ultimately into thre jugular vein

42
Q

Which skull structures is the cavernous sinus closely related to ?

A

Sphenoid bone, pituitary gland and optic chiasm

43
Q

Which arteries run through the cavernous sinus ?

A

Internal carotid arteries

44
Q

What fluid circulates the subarachnoid space ?

A

CSF

45
Q

What is the horizontal sheet of dura which is found in the brain ?

A

Tentorium cerebelli

46
Q

What is the vertical sheet of dura which is found in the brain ?

A

Falx Cerebri

47
Q

What bony structures does the falx cerebri attach anteriorly ?

A

The crista galli of the ethmoid bone and the frontal bone

48
Q

What is the name of the fold that connects the horizontal and vertical sheets of dura within the brain ?

A

Falx Cerebelli

49
Q

Which dural venous sinus runs within the upper border of the flax cerebri ?

A

Superior sagittal sinus

50
Q

Which dural venous sinus runs along the lower border of the falx cerebri ?

A

Inferior sagittal sinus

51
Q

Which venous sinus runs along the attachment if the two dural folds in the brain ?

A

Straight sinus

52
Q

To what bony points does the anterior edge of the of the tentorium cerebelli attach to ?

A

surface of the occipital bone which is where the transverse sinus runs along connectting to the petrous part of the temporal bone which runs along side the petrosal sinuses

53
Q

What is the fold of dura which is found around the pituitary stalk ?

A

Diaphragm Sallae

54
Q

Define a cerebral ventricle

A

Interconnected spaces/cavities that lie within the brain

55
Q

From which embryological structures are cerebral ventrciles formed from ?

A

Ependymal cells

56
Q

What are the names give to the specialized structures that lie in the ventricles and generate CSF ?

A

Choroid plexus

57
Q

How is the CSF reabsorbed ?

A

Arachnoid granulations

58
Q

What are association fibres?

A

Fibres which connect areas within the same cerebral hemisphere

59
Q

What are commissural fibres?

A

Fibres which connect 2 hemispheres of the brain i.e. corpus callosum

60
Q

What are projection fibres?

A

Fibres which unite the cortex with the lower parts of the brain and spinal cords
