Medullaris is an adjective used in the field of anatomy to describe structures that pertain to or are located in the medulla, specifically referring to the medulla oblongata or the spinal cord. The term derives from the Latin word "medulla," meaning marrow or pith. In anatomy, the medulla refers to the innermost part or core of a structure.
When medullaris is used to describe the medulla oblongata, it typically indicates its position or its association with this specific region of the brain stem.

It serves as a vital pathway for transmitting sensory and motor information between the brain and the rest of the body.
Therefore, the term medullaris in anatomy serves to identify structures associated with the medulla oblongata or spinal cord, highlighting their location, composition, or functional relevance within these particular parts of the central nervous system.
