epidural space
The epidural space is the area between the outermost layer of the spinal meninges and the inner walls of the vertebral canal. It contains areolar connective tissue, which provides flexibility and support, as well as adipose tissue, which serves as a cushioning layer and energy reserve. This combination of tissues helps protect the spinal cord and spinal nerves, while also allowing for movement within the vertebral column.
Adipose tissue is fat, while lymphedema is a swelling of tissues due to obstructed lymphatic drainage from a part of the body.
Adipose cells, or adipocytes, appear empty under a microscope because they are primarily composed of large lipid droplets that occupy most of the cell's interior. During the preparation of tissue samples, the lipids are often dissolved away, leaving behind a clear space that gives the cells their empty appearance. This characteristic is a hallmark of adipose tissue, which serves as a major energy storage site in the body.
Deep to the arachnoid layer of the meninges is the pia mater.
Adipose tissue surrounds and cushions the kidney, providing protection against physical damage. However, excessive adipose tissue (obesity) can have negative effects on kidney function as it can lead to inflammation and contribute to the development of kidney disease.

subarachnoid space
The meninges (from the Greek meninx, meaning "membrane") cover and protect the brain and spinal cord. The meninges have three layers: 1) the dura mater, 2) the arachnoid, and 3) the pia mater. The dura mater is the outermost layer covering the central nervous system. The arachnoid (from the Greek arachne, meaning "spider") is a web-like network of collagen and elastic fibers. The innermost layer of the meninges is the pia mater. The pia mater is firmly attached to the neural tissue of the spinal cord and brain. Cerebrospinal fluid fills the space between the pia matter and the arachnoid membrane. Most of the blood vessels that supply blood to the central nervous system are in the pia mater.
The five regions of space between the outer layer of the meninges and the cerebral cortex are the epidural space, subdural space, arachnoid mater, subarachnoid space, and pia mater. The epidural space is located between the dura mater and the skull, while the subdural space lies between the dura mater and arachnoid mater. The arachnoid mater is a web-like structure, followed by the subarachnoid space filled with cerebrospinal fluid, and finally, the pia mater directly covers the cerebral cortex. These layers protect the brain and provide cushioning, nutrients, and waste removal.
When the original tissue has been completely decomposed and the space filled in by mineralization.
