seminalis

Seminalis is a Latin adjective meaning related to seed or semen. In scientific terminology, it is used to form names and descriptions of structures or features connected with semen, or more broadly with seed-like characteristics. The form appears in phrases such as glandula seminalis (seminal gland) and vesiculae seminales (seminal vesicles), which are terms used in anatomical descriptions across various vertebrate groups.

In anatomy, the term appears most prominently in relation to male reproductive organs. The seminal vesicles, for example, are paired glands that contribute a substantial portion of the seminal fluid, providing nutrients and other substances that support sperm function. The Latin terminology reflects traditional taxonomic and descriptive practices in anatomy and comparative biology, rather than representing a single universal structure.

In taxonomy and nomenclature, seminalis may appear as a species or subspecies epithet in Latinized binomials or trinomials. Its exact meaning in a given name depends on the author's intended reference and is not standardized to a single anatomical feature. Outside of formal anatomical usage, the root also informs the English term seminal, which can mean relating to semen or, in a different sense, influential or pioneering; the latter meaning is not related to the Latin usage.
