which kind of terms is more frequently used in Anatomy terminology?

i am learning human anatomy now here in china, however, there are mainly two kind of medical terms i come across in our textbooks.

such as:

inferior nuchal line = linea nuchae inferior,
supra clavicular lymphnodes = Nodi lymphatici supraclaviculares,
inferior thyroid artery = A. thyroidea inferior

etc..

to me the former ones look more like english, and the latter ones seems more like Latin or something as it does not follow regular english grammar.

would some body be kind enough to tell me which kind of them are more frequently used internationally, or which of them are more popular in english textbooks used outside of china? should i know both of them, or just the former ones would be enough, as i am planing to further my education in med. schools overseas?
