Anatomy derives from Latin. Physiology, pathophysiology and operational terms derive from Greek.
Other English terms from the Greek root for “cut”: tomography (imaging through a lot of cross-sections); entomology (study of in-sects, critters with sect-ions in their bodies); dichotomy (division into two possibilities); atom (that which cannot be divided).
(Complaints about noun morphology sound a bit hypocritical from a native speaker of Russian, I know, but it is what it is.)
