KK: /ˈmaɪəˌskoʊp/
A device used to observe how muscles contract.
The scientist used a myoscope to study the muscle movements in the frog.
Myoscope is formed from "myo-" (from Greek "mus" meaning muscle) and "scope" (from Greek "skopein" meaning to look or examine). The word refers to an instrument used to examine or observe muscles.
Think of 'muscle' ('myo-') and 'looking' ('scope') to remember that a myoscope is a device for examining muscles.
