A. heart is involuntary and unstirated smooth
B. intestine is striated and involuntary
C. thigh is striated and voluntary
D. upper arm is smooth muscle and fusiform in

Answer

### Step-by-Step Solution:

1. **Understanding Muscle Types**: There are three main types of muscle tissues in the human body: voluntary (striated), smooth (involuntary), and cardiac (involuntary but striated).

2. **Voluntary Muscles**: These muscles can be controlled consciously. They are also known as striated muscles due to their appearance under a microscope, which shows alternating light and dark bands. These muscles are primarily associated with the skeletal system, hence they are often referred to as skeletal muscles.

3. **Smooth Muscles**: These muscles are involuntary and cannot be controlled consciously. They do not have striations and are found in the walls of internal organs, which is why they are also called visceral muscles.

4. **Cardiac Muscles**: Found exclusively in the heart, cardiac muscles are striated like voluntary muscles but function involuntarily. This means we cannot consciously control the heartbeat.

5. **Analyzing the Options**:
- The first option states that the muscles present in our heart are involuntary but describes them as unstriated smooth muscles. This is incorrect because cardiac muscles are striated.
- The second option states that the muscles in our thigh are striated and voluntary. This is correct as these are skeletal muscles.
- The third option claims that the muscles in our upper arm are smooth. This is incorrect; upper arm muscles are striated and voluntary.
- The fourth option states that the muscles in the intestine are voluntary and striated. This is incorrect as intestinal muscles are smooth and involuntary.

6. **Conclusion**: The only correct statement is that the muscles in our thigh are striated and voluntary.

### Final Answer:
The type of muscle present in our thigh is striated and voluntary.
