meninges: Definition and Much More From Answers.com (2465 words)
The meninges are composed of the dura mater (outer), the arachnoid (middle), and the pia mater (inner).
The outermost, the dura mater, is a tough, fibrous, double-layered structure that is adherent to the skull.
Normally, the dura mater is attached to the skull in the head, or to the bones of the vertebral canal in the spinal cord.
Pia mater - Wikipedia, the free encyclopedia (179 words)
