PERIMEDULLARY Meaning and
Definition
-
Perimedullary refers to any structure or process that surrounds or occurs in the area surrounding the spinal cord. The word perimedullary is derived from the prefix "peri-", meaning around or near, and the term "medullary", which is related to the medulla or the innermost part of a structure. In the context of the spinal cord, perimedullary specifically describes the structures, spaces, or conditions that exist around the spinal cord.
Perimedullary structures can encompass various elements, such as blood vessels, nerves, tissues, or spaces. For example, perimedullary veins are veins that surround or closely follow the course of the spinal cord, facilitating the exchange of blood and nutrients. Perimedullary spaces, on the other hand, are the fluid-filled areas surrounding the spinal cord, which provide protection and cushioning.
Medical conditions or procedures related to the perimedullary region often refer to abnormalities or treatments that involve the area surrounding the spinal cord. This can include perimedullary tumors, which are tumors located around the spinal cord, or perimedullary angiography, a diagnostic procedure that involves injecting a contrast agent into the blood vessels surrounding the spinal cord to visualize their structure and function.
In summary, perimedullary pertains to structures, spaces, processes, or conditions that are situated around or in the vicinity of the spinal cord.
