## What is 3D Muscle?

This app creates a detailed 3D model using MRI images. It displays a realistic solid model of all the bones and muscles in the upper and lower limbs, which can be rotated freely on the screen.

Features:
- Display the muscles in any combination of your choice, both individually and in groups (Flexors, Extensors).
- Rotate the model 360 degrees, with a swipe of your finger.
- Zoom in/out crystal clear images.
- Text information about the muscles (Origin, Insertion, Innervation, Action).
- Show muscle attachment areas in color.

Add-ons :
- Arm
- Forearm
- Hand
- Upper Limb (include those 3 parts)

- Thigh
- Leg
- Foot
- Lower Limb (include those 3 parts)

Note: If you lost purchased add-ons, please tap the "Restore" button.

About the 3D Model:
Based on high resolution MRI images of an adult male, interprets the contours of each muscles, and then combines all the contour data to build a 3D model. This model provides an accurate 3D positional representation of the muscles in a living body.

### 4/5 — Best app I could find

*2012-11-17, version 1.0.0*

You can single out individual muscles and quickly learn their function from just looking at the model. Same with bones. Multicolors are very convenient. The best app I could find to learn muscle and skeleton anatomy. Only 4 stars out of 5, because there is no connective tissue in the model.
