Q

Role of CSF

A

Cushioning

Lymphatic and extra line of defence against altered homeostasis

17
Q

What is the blood brain barrier

A

Tight basement membrane and tight capillary junction with no openings/gaps

18
Q

What is the role of the blood brain barrier

A

Extra line of defence

prevention of changes in ionic conc. affecting brain excitability

19
Q

When is the BBB permeable to antibodies

A

When it is inflamed the leakage increased

20
Q

Where is there no BBB at

A

Vomiting centre- needs to detect toxins

Hypothalamus - needs to sense osmolality
