The other two meningeal layers are the arachnoid mater and the pia mater.
2.
The cerebrospinal fluid that surrounds the spinal cord is contained by the arachnoid mater.
3.
The arachnoid mater is the middle protective layer.
4.
Most meningiomas grow from the arachnoid mater inward applying pressure on the pia mater and therefore the brain or spinal cord.
5.
In contact with the inner surface of the dura is another membrane called the arachnoid mater ( " arachnoid " ).
6.
They are called ( from the outside to the inside ) the dura mater, the arachnoid mater and the pia mater.
7.
Sandwiched between the dura and arachnoid maters lie some veins that connect the brain's venous system with the venous system in the dura mater.
8.
Other patients have seen the onset of bobble-head doll syndrome from the presence of a suprasellar cyst in the arachnoid mater of the meninges.
9.
The CSF occupies the subarachnoid space ( between the arachnoid mater and the pia mater ) and the ventricular system around and inside the brain and spinal cord.
10.
The arachnoid mater and dura mater are very close together throughout the cranium all the way to S2, where the two layers fuse into one layer and terminate.
