A

No clear division sepesrating it

20
Q

Frontal

A

Movement desicion making planning rational thought

21
Q

Pariental lobe

A

Attention and representation of space around us

22
Q

Temporal lobe

A

Process auidory signals memory

23
Q

Occipital lobe

A

Visual process area of brain

24
Q

What 2 nerves filiments does the spinal cord have attached

A

Nerve arising from dorsal and another from ventral

25
Q

What strong protective layer lines the vertebral canal

A

Dura

26
Q

What lines the dura

A

Arachnoid

27
Q

What membrane attaches firmly to the spinal cord

A

Pia

28
Q

What is the name of the space between the arachnoid and oil

A

Subarachnoid space filled with cerebral spinal fluid

29
Q

What is the space between the dura and vertebral canal Called

A

Epidral space filled fat blood vessels loose connective tissue

30
Q

Why does the cord only fill the upper 2/3 of the vertebral canal

A

In embryo it fills all but the canal grows faster than the cord

31
Q

Meninges is what

A

3 membrane s
Dura matter
Arachnoid matter
Pia matter

32
Q

Function of meninges

A

Protect and provide structural support too brain and contain cerebral spinal fluid

33
Q

Dura matter attached to what

A

Attached to skull and arachnoid matter

34
Q

Function of dura

A

Provide extra layer to brain and spinal cord
Attached brain to skull
And spinal cord to vertebral column
To stop them moving
Provide venous drainage so blood can leave brain

35
Q

Arachnoid trabeculae is what and does what

A

Strands of connective tissue between arachnoid and pia

Keep brain in place

36
Q

Pia matter is what and does what

A

Tight membrane around b and sc
Additional barrier
Secrets and contains cerebrospinal fluid

37
Q

Lumbar cistern

A

Region at bottom of vertebral canal

Cerebral spinal fluid filled area with no spinal cord

38
Q

What supplies blood to brain

A

Internal carotid artery bout 80%

Vertebral artery bout 20%

39
Q

What do the internal carotid artery spilt to once entering brain

A

Anterior and middle cerebral arteries

40
Q

What do the anterior cerebral artery supply

A

Medial frontal parietal lobes

41
Q

What does the middle cerebral arteries supply

A

Supply most of lateral surface of cerebral hempsihere

42
Q

What does the vertebral arteries spilt to

A

Posterior inferior cerbellwr artieres

Supply inferior surface of cerebellum

43
Q

What are ventricle

A

Network of cavities that are distributed in brain

44
Q

What are the ventricles lined with

A

Choroid plexus

45
Q

What cells make up the choroid plexus

And their function

A

Ependymal cells

Specialise to secrete cerebrospinal fluid

46
Q

Main roles of ventricles

A

Production and secretion of cerebrospinal fluid

47
Q

Function of csf in brain

A

Protective layer
Reducing strain forces like gravity
Removes toxins
