Good app., some detail missing
I use this app. to determine origins and insertions of muscles for targeted Reflexology and Applied Kinesiology. It is very helpful, except that some muscles have multiple divisions that are shown as one instead of as separate divisions. For example, Longus Colli is shown in the app. as one muscle, however, it has three divisions, Superior Oblique, Vertical, and Inferior Oblique, each with distinct origins and insertions, and each with a unique head position for functional testing. There are likely other muscle divisions that are grouped, as well.
