The Epidural Space Contains
The epidural space contains. In anatomy the epidural space is the potential space between the two layers of the dura mater. In humans the epidural space contains lymphatics spinal nerve roots loose connective tissue adipose tissue small arteries dural venous sinuses and a network of internal vertebral venous plexuses. The upper limit of the epidural space is the foramen magnum which is the point where the spinal cord enters the base of the skull.
The anatomy term epidural space has its origin in the ancient greek language. The epidural veins are a part of the large internal vertebral venous plexus which communicates with the occipital sigmoid and basilar sinuses superiorly in the cranium. The dura is the outermost layer of the covering called the meninges that surrounds the spinal cord.
The fat in the epidural space helps absorb shock which protects the other contents in the area as well as the dura.
