Study Notes
Protective Membranes of the Brain and Spinal Cord
- The brain in the skull is surrounded by three protective membranes called meninges.
- The three meninges are: • Dura mater • Arachnoid mater • Pia mater
- The spinal cord in the vertebral column is also surrounded by these three meninges.
Layers of the Dura Mater
- The dura mater has two layers.
- The two layers are: • Endosteal layer • Meningeal layer
- The two layers are closely united except where they separate to form venous sinuses.
