Brain :</h3>
It is highly complicated and highly specialized organ of the body.
An adult human brain weighs about 1400gms . in new born babies it is 400gms.
it has a volume of about 1500 c.c.
it is enclosed in a bony case called cranium which protects brain against external injury.
The brain is surrounded by three membranes called meninges. it protects the brain from external shock.
the meninges are outer duramater ,middle arachnoid,and inner piamater.
piamater is a thin, transparent and vascular membrane close to the surface of brain and spinal cord .
At two places the piamater fuses with the thin, dorsal surface of the brain to form choroid plexus.
The space between duramater and arachnoid is the subdural space and the space between arachnoid and piamater is called subarachnoid space.
These spaces surrounding the brain as well as the cavities within the brain are filled with a lymphatic fluid,called cerebrospinal fluid.
Cerebrospinal fluid protects the central nervous system from external shock,helps in exchange of nutrients and waste products between the nervous tissue and blood and maintains a constant pressure in and around the brain.
