3. FEATURE-
●
The brain is a very important delicate organ.
● It is projected by the following covering
1. Bony covering of the cranium.
2. Three membranous covering [MENINGES]
Inner to outer.
1. Pia matter
2. Arachnoid matter.
3. Duramatter.
The arachnoid and pia matter are together knows the laptomaninges and space of manenges.
● Extradural/epidural
● Subdural
● Subarchnoid
● The csf are fills in the space between arachnoid and pia .
● The brain almost flat in the csf.
● The csf help in shock free environment

4. Duramatter-.
The duramatter are made up of two layer outer endosteal layer.
The meningeal layer .it present cranial venous
The meningeal layer form 4 fold .
● Flax cerebri-- scikle shaped
● Tentorium cerebelli-. - tent shap.
● Flax cerebelli-. Small sickele shape.
● Diaphragm sellae - small horizontal fola
ARACHNOID MATTER.
It's thin transparent membrane.
It loosely sorrounds the brain without depping
It inter the sulcus/fissure
● The Stem of lateral sulcus where it is pushed.
● Longitudinal cerebral fissure present.
● It cannot be identifid in the hypophyseal fossa
