Masculine nouns (masculinum)
Certain terms, despite their endings, historically belong to the masculine gender. In anatomical nomenclature, these are fundamental words without which the skeletal, muscular, and vascular systems cannot be described.
Key masculine exceptions include:
- axis, is — axis, and the specific designation for the second cervical vertebra;
- canālis, is — canal;
- dens, dentis — tooth;
- pons, pontis — pons/bridge;
- margo, ĭnis — margin/border;
- sanguis, ĭnis — blood;
- tendo, ĭnis — tendon.
When agreeing with these nouns, adjectives must also take the masculine form.
Feminine nouns (femininum)
This group includes terms denoting vital internal organs and structures.
Main feminine exceptions:
- gaster, tris — stomach.
- mater, tris — a word with two meanings: 1) mother; 2) meninx/mater.
In anatomy, the term mater is actively used to denote the membranes covering the brain and spinal cord. Feminine adjectives agree with it, forming fixed terminological combinations:
- dura mater — dura mater.
- pia mater — pia mater.
- arachnoidea (mater) — arachnoid mater.
Neuter nouns (neutrum)
Neuter words constitute a significant portion of clinical and anatomical vocabulary. The third declension contains a number of short and frequently used exception words.
List of neuter exceptions:
- os, oris — mouth;
- os, ossis — bone;
- cor, cordis — heart;
- tuber, eris — tuber/tuberosity;
- vas, vasis — vessel.
A Greek borrowing that also became a neuter exception in Latin deserves a separate mention: pancreas, ătis — pancreas.
Briefly: answers to topical questions

Which Greek borrowings ending in -ma (e.g., chiasma) belong to the neuter gender of the third declension?
In study guides, the Greek neuter borrowings of the third declension ending in -ma include the following anatomical terms:
- Diaphragm (diaphragma, ătis n)
- Stroma (stroma, ătis n)
- Zygoma (zygōma, ătis n)
- Chiasm (chiasma, ătis n)
- System (systēma, ătis n)
To memorize masculine exceptions, you can use the anatomical mnemonic: "Blood (sanguis) flows through a canal (canalis) into a tooth (dens), while a tendon (tendo) attaches to the margin (margo) of the axis (axis) of the pons (pons)."
