Morphology

os + longum

The compound combines 'os' (bone) with 'longum' (Latin adjective meaning 'long'), so the sense 'long bone' is directly derivable from the constituents. Although the term is technical and Latin in form, a B1 learner who knows both constituent meanings would readily infer the MWE's meaning.

Etymology

Os longum comes from Latin: os means 'bone' and longum means 'long'. So the name describes the long, thin bones in the arms and legs.
