What do the spinal meninges do quizlet?
Provide physical stability and shock absorption while providing oxygen and nutrient to the spinal cord tissue.
What are meninges quizlet?
What are meninges? Membranes of connective tissue that surround and protect the brain and spinal cord (CNS)
How does the epidural space of the spinal cord differ from that surrounding the brain?
Around the spinal cord, the epidural space is a true space, which is usually filled with fat tissue, blood vessels, and nerves. Around the brain, the epidural space is lacking, or represented only as a potential space.
What protects dura mater?
Dura mater is a thick membrane made of dense irregular connective tissue that surrounds the brain and spinal cord. It is the outermost of the three layers of membrane called the meninges that protect the central nervous system….
| Dura mater | |
|---|---|
| TA2 | 5370 |
| FMA | 9592 |

What is the thecal sac quizlet?
Thecal sac. A protective sac surrounding the spinal cord formed by the meninges. It attaches to the rim of the foramen magnum and ends at the second sacral vertebra. Epidural space.
What do spinal meninges do?
The spinal meninges are three membranes that surround the spinal cord – the dura mater, arachnoid mater, and pia mater. They contain cerebrospinal fluid, acting to support and protect the spinal cord.
What is the space within the meninges of the spinal cord that contains the cerebrospinal fluid quizlet?
The subarachnoid space within the meninges contains cerebrospinal fluid.
What is the function of meninges?
The meninges: Protect your CNS (central nervous system) from trauma injury to your brain, such as a blow to your head by acting as a shock absorber. They anchor your CNS and keep your brain from moving around within your skull.
What are the 3 meninges and their characteristics?
Three layers of membranes known as meninges protect the brain and spinal cord. The delicate inner layer is the pia mater. The middle layer is the arachnoid, a web-like structure filled with fluid that cushions the brain. The tough outer layer is called the dura mater.
What are the spinal meninges?
INVESTING MEMBRANES (MENINGES) Three membranes surround the spinal cord: The outermost is the dura mater (dura), the next is the arachnoid, and the innermost is the pia mater (pia) (Figs 6–1 and 6–2). The dura is also called the pachymeninx, and the arachnoid and pia are called the leptomeninges.
