Terms describing bones and skeletal parts
To describe the skeletal framework, a number of basic nouns are used in Latin. The primary term is the word for bone — os, which in the genitive case takes the form ossis and belongs to the neuter gender (n).
Main bone structures:
- cranium, i n — skull;
- costa, ae f — rib;
- vertebra, ae f — vertebra;
- scapula, ae f — scapula;
- ulna, ae f — ulna.
Special mention should be made of the terms designating the jaws. For the upper jaw, the word maxilla, ae f is used, and for the lower jaw — mandibula, ae f. Both of these nouns are feminine.
Relief elements and anatomical structures
Anatomical structures rarely have a flat surface. Specialized terms are used to describe their complex relief. Prominent parts include the crest (crista, ae f), spine (spina, ae f), and horn (cornu, us n).
Depressions, openings, and cavities are described by the following words:
- cavĭtas, ātis f — cavity;
- incisūra, ae f — notch;
- sulcus, i m — sulcus;
- orbĭta, ae f — orbit;
- meātus, us m — meatus or passage;
- concha, ae f — concha.
To designate parts of various structures, the words corpus, oris n (body), caput, itis n (head), angulus, i m (angle), arcus, us m (arch), lamĭna, ae f (lamina), and ala, ae f (wing) are used. Boundaries and divisions are designated by the terms linea, ae f (line) and septum, i n (septum).
Soft tissues, vessels, and internal organs
General anatomical terminology also includes words for designating soft tissues, the vascular bed, and individual organs.
| Latin term | Genitive case | Genus | Translation |
|---|---|---|---|
| muscŭlus | i | m | muscle |
| ligamentum | i | n | ligament |
| aorta | ae | f | aorta |
| arteria | ae | f | artery |
| vena | ae | f | vein |
| ductus | us | m | duct |
| lingua | ae | f | tongue |
| brachium | i | n | arm |
| tympănum | i | n | drum |
This group contains nouns of all three genders: masculine (m), feminine (f), and neuter (n).
Features of nouns of Greek origin
Anatomical nomenclature includes words borrowed from the Greek language that retain their grammatical features. An important rule concerns nouns ending in the nominative case with the letter -e.
Such Greek terms belong exclusively to the feminine gender (f), and in the genitive singular (Gen. sing.) they acquire the ending -es. The only example of such a word in this list is raphe, es f, which translates as "raphe" (denoting a junction of soft tissues, tendons, or muscles, as opposed to bone sutures).
Briefly: answers to topical questions
What Latin terms are used to designate various types of openings and canals in bones?
To designate openings, canals, passages, and clefts, the sources provide the following Latin terms:
- Opening — foramen.
- Canal — canalis.
- Canaliculus — canaliculus.
- Passage, meatus — meatus, us m.
- Cleft — fissura; hiatus is also found.
- Aperture (opening) — apertura.
What is the dictionary form of the Latin terms designating internal organs (heart, lung, liver, kidney)?
The dictionary forms of the Latin terms designating the listed internal organs are as follows:
- Heart (cor, cordis n).
- Lung (pulmo, ōnis m).
- Liver (hepar, ătis n).
The dictionary form for the kidney is not given in full in the sources (only the forms ren and renis are encountered).
How does the usage of the terms sutura and raphe differ in anatomical terminology?
The terms sutura and raphe in anatomical terminology are translated as "suture", but they differ significantly in the type of tissues they connect.
| Term | Significance | Administration |
|---|---|---|
| sutura, ae f | suture (bone) | Used to designate the connection of bones (e.g., serrate and flat sutures of the skull). |
| raphe, es f | raphe | Denotes the site of fusion of soft tissues, tendons, and muscles (e.g., perineal raphe). |
How are the main parts of a vertebra (body, arch, processes) translated into Latin?
The main parts of a vertebra (vertebra, ae f) are translated into Latin as follows:
- Vertebral body (corpus vertebrae).
- Vertebral arch (arcus vertebrae).
- Process (processus, us m).
Sources also mention specific types of processes: transverse process (processus transversus), articular process (processus articularis), and spinous process (processus spinosus).
Which Latin terms are used to denote joints and their elements (cartilage, capsule)?
The following Latin terms are used to denote joints and their elements:
- Joint (articulatio, onis f).
- Cartilage (cartilago).
- Capsule (capsula).
Terms used to describe joint elements also include: articular surface (facies articularis), articular fossa (fovea articularis), and articular meniscus (meniscus articularis).
To remember the rule regarding Greek terms: if a word ends in an unusual -e (like raphe), it means we add -s in the genitive case (raphe -> raphes), and it is always feminine.
Class and exam questions
What is the grammatical feature of the term raphe?
The word raphe (seam) is of Greek origin. It ends in -e, belongs to the feminine gender, and in the genitive singular takes the ending -es (raphe, es f).
How are the jaws designated in Latin?
In Latin, the term mandibula, ae f is used for the mandible. The maxilla is denoted by the word maxilla, ae f.
What gender is the word os (bone) and how does it decline?
The term os translates as "bone" and belongs to the neuter gender (n). In the genitive case, it takes the form ossis.
