Answer

**Step-by-Step Solution:**

1. **Identify the Types of Muscles**: There are three main types of muscles in the human body: skeletal (striated), cardiac, and smooth muscles.

2. **Muscle in the Upper Arm**: The upper arm primarily contains skeletal muscles, which are striated and under voluntary control. These muscles are responsible for movements such as lifting and pushing.

3. **Heart Muscle**: The heart contains cardiac muscle, which is involuntary and striated. It is not classified as smooth muscle.

4. **Muscle in the Intestine**: The intestines are lined with smooth muscle, which is involuntary and non-striated. This muscle type helps in the movement of food through the digestive tract.

5. **Muscle in the Thigh**: The thigh also contains skeletal muscles, which are striated and voluntary. These muscles allow for movements such as walking and running.

6. **Conclusion**: The types of muscle present in the arm are striated (skeletal) muscles, which are voluntary.
