More about these tools

The ear follows in one section from the auricle to the cochlea, with 17 numbered rings. Maps of the brain and the nerves join the list one at a time, each when its drawing has been checked against its part list.

Every page is one drawing. Find it names a part for you to tap, Name it lights a ring for you to name, and Study shows every label with a line about the part. After a round, one press replays the parts you missed, and each drawing prints blank or labeled. These pages teach names and places and give no medical advice.
