The dura mater is separated from the walls of the vertebral canal by an epidural space, which contains fat and blood vessels. This space provides cushioning and allows for flexibility within the spinal column. Additionally, the dura mater itself is a tough, outermost layer that protects the spinal cord and its surrounding structures.

What are lateral extensions of pia mater into the vertebrae?

The lateral extensions of the pia mater into the vertebrae are called denticulate ligaments. They anchor the spinal cord to the dura mater within the vertebral canal and help stabilize the spinal cord within the spinal column.

Structures that form an enclosure for the spinal cord?

The boney structures are the Vertebral Foramina. The spine is "divided" into the Cervical Spine (neck), the Thoracic Spine (chest & Ribs), Lumbar spine (lower back) anc Coccyx, or "tailbone".


What is the space in the meninges that is filled with adipose tissue?

The epidural space is the space in the meninges that is filled with adipose tissue. This space is located between the dura mater and the vertebral canal, providing cushioning and support for the spinal cord.

What is the medical term meaning collection of blood above the dura mater?

Epidural is the medical term meaning above the dura mater, or the area between the dur mater and the vertebral body.


Separates dura mater from bone of vertebra?

The epidural space separates the dura mater from the bone of the vertebra. This space is filled with fat and blood vessels and is where epidural injections are commonly administered to deliver medication for pain relief. The dura mater is a tough, fibrous membrane that surrounds the brain and spinal cord, providing protection and support.


What mechanical layer lies above the cord?

The mechanical layer that lies above the spinal cord is the vertebral column, commonly known as the spine. It consists of vertebrae that provide structural support and protect the spinal cord. Additionally, surrounding the spinal cord are protective membranes called meninges, which include the dura mater, arachnoid mater, and pia mater. These structures collectively ensure the integrity and safety of the spinal cord within the vertebral column.


What is the difference between meninges of the spinal cord and the brain?

The dura mater in the brain is fused to the periosteum vs in the spinal cord the epidural space is in between the dura mater and the intervertebral canal.Three fibrous membranes that surround the brain and spinal cord to protect the central nervous system. The pia mater, a very thin membrane, adheres to the surface of the brain and spinal cord. The subarachnoid space, containing cerebrospinal fluid, separates the pia mater from a second membrane, the arachnoid. Around the brain, fine filaments connect these two membranes, which are believed to be impermeable to fluid. The third membrane, the dura mater, is strong, thick, and dense. It envelops the arachnoid, covers the inside of the skull, and surrounds and supports the large venous channels carrying blood from the brain. Several septa divide it and support different parts of the brain. In the spine, the dura mater and the arachnoid mater are separated by the subdural space; the arachnoid and pia mater are separated by the subarachnoid space. The extradural space (between the dura mater and the wall of the vertebral canal) is the site of epidural anesthesia (see anesthesiology).


What separates the cerebral hemispheres?

You have the beautiful partition called as falx cerebri, which separates the cerebral hemisphere incompletely. This partition is made from the folding of the inner layer of the Dura mater. Dura mater is the outer covering of the meninges.
