EXTRAMEDULLARY Meaning and
Definition
-
Extramedullary is an adjective that refers to something occurring or existing outside of the medulla, which is the soft, innermost part of certain anatomical structures. This term is commonly used in medical contexts, particularly in relation to the nervous system and spinal cord.
In the context of the nervous system, extramedullary usually refers to structures or processes that occur or develop outside of the spinal cord. For example, extramedullary tumors are abnormal growths that develop in the tissues surrounding the spinal cord, whereas intramedullary tumors grow within the substance of the spinal cord itself. Similarly, extramedullary hematopoiesis refers to the formation of blood cells outside of the bone marrow, often occurring in response to certain medical conditions or diseases affecting the bone marrow's normal function.
Outside of the nervous system, extramedullary can also refer to structures or processes occurring outside of any other medullary structures found in different organs or tissues. For instance, extramedullary hematopoiesis may also occur in the liver or spleen.
Overall, the term extramedullary describes anything that is situated, occurring, or originating outside of the medulla. Its usage helps to distinguish between different anatomical structures and their respective locations, aiding in accurate medical diagnoses and treatment recommendations.
