# HumanBone

> The mapping between a bone in the model and the conceptual bone in the Mecanim human anatomy.

## Definition

* **Type:** Struct
* **Namespace:** [UnityEngine](/engine/6000.7/script-reference/unityengine.md)
* **Assembly:** UnityEngine.AnimationModule

```csharp
public struct HumanBone
```

## Remarks

The names of the Mecanim human bone and the bone in the model are stored along with the limiting muscle values that constrain the bone's rotation during animation.
