I think there are a couple mistakes (some are just spelling mistakes). One I like to point out is that the serratus posterior inferior is attached to T11-L2 not T11-L3. If some of the mistakes can be weeded out this program is great to solely rely on for studying on-the-go. Also just a suggestion, it would be awesome if in the comments section one can add/write his or her own comments. Love the pronunciation feature!
