OTHER FEATURES:

• Use your finger to Cut - slice skeletal areas for a coronal, sagittal and transverse cut view (where applicable) - use hints to learn how.
• Press the Scalpel - to add or remove up to 4 layers of connective tissue.
• Pins appear in both English and Latin.
• Double Tap again for additional Zooming - useful when there are multiple pins.

The Skeletal System Pro III - includes the most in depth 3D skeleton ever developed, the ability to rotate, cut and get superior/inferior views all with the simple stroke of the finger.

This app’s primary use is as a learning tool but can also be used as a fast and innovative reference tool by utilizing the index function which allows the user to select an item and the app will automatically zoom in and identify it.

Additionally, this app is ideal for physicians, educators or professionals, allowing them to visually show detailed areas of the skeletal system to their patients or students - helping to educate or explain conditions, ailments and injuries.
