The detailed 3D rendering of the young human muscular arm, with its vibrantly colored anatomy, is ideal for studying the structure and function of the muscles in the human arm. Key anatomical parts are colored and numbered for comparison with the anatomy key that is included. The arm itself can be removed from the base and the model also has 5 muscles that can be removed for further exploration of the anatomy underneath the muscles down to the bone (including main nerves and tendons). This model provides a visually and kinesthetically effective method for studying the structure and function of the human child's arm.
