Morphology
myosin = myo (opaque) = myo + in
The combining form 'myo-' is a specialised scientific element (not a familiar standalone word like 'muscle'), and the protein suffix '-in' is technical, so the sense is not derivable by an average B1 learner from common vocabulary.
Etymology
The word myosin comes from the Greek beginning myo- meaning 'muscle', a word that also once meant 'mouse' because people thought muscles looked like little mice under the skin, and the ending -in is used for proteins. So, myosin is a protein in muscles that helps them move.
