rdzeniowemu

Rdzeniowemu is the dative singular form of the Polish adjective rdzeniowy, which means related to the spinal cord or to a medullary/central spine in anatomical and medical contexts. The base rdzeniowy derives from rdzeń, meaning core, kernel, or spinal cord, and the -owy suffix forms adjectives used to describe nouns.

In grammar, rdzeniowemu is used when the modified noun is masculine or neuter and in the dative case. The masculine/neuter dative form is rdzeniowemu, while feminine forms appear as rdzeniowej (dative feminine). As with other adjectives, the form must agree with the gender, number, and case of the noun it modifies. In practice, rdzeniowemu appears in constructions such as rdzeniowemu odcinkowi kręgosłupa (to the spinal segment) or rdzeniowemu elementowi układu nerwowego (to the spinal/medullary element of the nervous system).

Usage notes: rdzeniowy is commonly employed in medical and anatomical terminology to denote relation to the spinal cord or to elements associated with it. Although rdzeniowemu is most often encountered as part of longer noun phrases, speakers rely on context to determine whether it references spinal features or, more broadly, medullary attributes.
