mózgowordzeniowym

Mózgowordzeniowy is an adjective used in Polish to describe relations or pathologies involving both the brain and the spinal cord. In Polish grammar, mózgowordzeniowym is the instrumental singular form of this adjective, used with masculine nouns in contexts such as "system mózgowordzeniowym" (brain–spinal system).

In medical terminology, the more common hyphenated form is mózgowo-rdzeniowy, which clearly links mózg and rdzeń. The fused form mózgowordzeniowy appears in some texts as a condensed variant, especially when used in compounds such as układ mózgowordzeniowy or choroby mózgowordzeniowe. The term derives from the combining forms mózgowo- (brain-related) and rdzeniowy (spinal cord-related).

It is used primarily in neurology, anatomy, and pathology to indicate involvement of both brain and spinal cord; it can describe structures, pathways, or processes that span both regions. In writing, the hyphenated form is often preferred for clarity, while the single-word form may be found in older literature or stylistic shortcuts. In English, the closest equivalent is cerebrospinal, as in cerebrospinal fluid (płyn mózgowo-rdzeniowy).

See also central nervous system. The term remains specialized and predominantly appears in technical or scholarly contexts rather than everyday language.
