2. **Myocardium**: This is the middle layer and is primarily made up of cardiac muscle tissue.
3. **Endocardium**: This is the inner layer that lines the heart chambers.

### Step 2: Identify the Location of Cardiac Muscles
Cardiac muscles are specifically found in the **myocardium**. This layer is responsible for the heart's ability to contract and pump blood throughout the body.

### Step 3: Conclusion
Based on the information about the layers of the heart, we conclude that cardiac muscles are found in the **myocardium**.

### Final Answer
