Q

<p>what do microglia cells do </p>

A

<p>macrophage like cells
immune monitoring and antigen presenting

live inside CNS waiting for infection - when activates processes pull in and they become like macrophages </p>

Q

<p>what are fissures </p>

A

<p>just deep sulci - can press finger in and it disappears lol </p>

20
Q

<p>where is grey matter located in the brain </p>

A

<p>around the outside

| also grey matter cord in middle of brain </p>

21
Q

<p>what makes up grey matter </p>

A

<p>Neuron body cells

| Glial cells </p>

22
Q

<p>where is white matter located in the brain </p>

A

<p>forms the core </p>

23
Q

<p>what makes up white matter </p>

A

<p>ONLY neuron cell processes NOT BODIES

support cells </p>

24
Q

<p>where is the grey matter in the spinal cord </p>

A

<p>on the INSIDE </p>

25
Q

<p>where is the white matter in the spinal cord </p>

A

<p>on the OUTSIDE </p>

26
Q

<p>what shape does the grey matter take on in the spinal cord </p>

A

H shape - made up of 2 posterior and 2 anterior horns

white matter forms columns around this

Frontal
parietal
temporal
occipital

32
Q

where is the demarcation point of the visual cortex

A

Calcarine sulcus

33
Q

what is the corpus callous

A

big band of white matter

communication point between one hemisphere and the other

34
Q

what does the 4th ventricle sit between

A

cerebellum and pons

35
Q

what is the insular lobe

A

a 5th lobe located underneath the temporal lobe - deep to others

important in experience of pain

36
Q

what are the 3 meninges

A

Dura mater
Arachnoid mater
Pia mater

37
Q

where is the 3rd ventricle located

A

between the lateral ventricles

38

between medulla and pons

39
Q

where is CSF made

A

choroid plexus

40
Q

CSF circulation summary

A 
choroid plexus 
two lateral ventricles 
to third ventricle 
to forth ventricle 
to central canal of spinal cord or into subarachnoid space leading to reabsorption by venous system
41
Q

what does CSF travel through to get from the lateral ventricles to the 3rd ventricle

A

inter ventricular foramen

42
Q

what does CSF travel through to get from the 3rd to the 4th ventricle

A

cerebral aqueduct

43
Q

what is the enteric nervous system

A

Gut’s own nervous system - 2 large plexuses in gut

44
Q

what is the arterial blood supply to the brain

A 
Internal carotids 
Basilar artery (runs along base) 
Anterior cerebral arteries 
Middle cerebral arteries 
vertebral arteries

Circle of willis in middle

45
Q

how is blood drained from the brain

A

inter cavernous sinuses

cavernous sinuses

Via the dural venous sinuses which train into the internal jugular vein
