MEDULLARY Meaning and
Definition
-
Medullary is an adjective that refers to anything related to or situated in the medulla, which is the innermost part of an organ or structure. The term is commonly used in reference to the medulla oblongata, which is the lower portion of the brainstem responsible for regulating vital functions such as breathing, heart rate, and blood pressure.
In the context of anatomy, medullary can also describe tissues that resemble or are associated with the medulla. For example, medullary bone is a type of spongy bone found inside the shafts of long bones, which is distinct from the harder cortical bone that surrounds it. Medullary tissue can also refer to the soft, inner part of certain organs or glands, such as the medullary region of the adrenal gland.
In the field of medicine, medullary is a term often used to describe certain types of tumors or cancers that originate in the medulla or medullary tissue. One well-known example is medullary carcinoma of the thyroid, a rare type of thyroid cancer that typically has a poorer prognosis compared to other forms.
Overall, the term "medullary" denotes a connection to the innermost part of an organ or structure, particularly the medulla oblongata in the brainstem, but can also be used to describe tissues, tumors, or conditions associated with the medulla.
