function of cerebrospinal fluid

 Function of CSF

Mechanical protection

Chemical protection

Circulation

Prevention.of brain ischemia

Regulation brain function

Blood brain barrier( BBB);  protection

Help in maintaining homeostasis and metabolism of brain (CNS)

Mechanical protection

CSF supports and protect brain and spinal cord 

Shock absorbing between brain and skull 

Maintain uniform pressure

Shock absorber

Coushin brain against skull

Chemical function

Maintaining chemical environment of brain

Regulation brain function

CSF formation and absorption

Circulation

Medium for exchange of nutrients and waste product between blood and nervous tissue.

Act as fluid buffer.

Prevention of brain ischemia 

(in decrease amount of CSF, insufficient blood flow)

Blood brain Protection; BBB

Prevent entry of blood constitutent in brain
